Keep Your Pet Healthy During the Winter Months

As we approach the colder months and the Holiday season, it is important to remember some dangers pets face during this time of year.
Antifreeze
Most antifreeze contains ethylene glycol as an active ingredient which is toxic to animals. Antifreeze has a sweet taste. Because of this, dogs and cats will drink it. Antifreeze can be lethal, causing permanent, fatal kidney damage. Keep pets away from any spilled antifreeze or containers of antifreeze. Even antifreeze that has been diluted in the car's radiator can have enough toxic ethylene glycol to be fatal to your pet. If you suspect your pet has ingested antifreeze, call your veterinarian immediately.

Dietary Indiscretion and Pancreatitis

We all like to include our pets in Holiday meals along with the rest of the family. However, keep in mind that sudden, rich, high fat diet changes are likely to upset your pet's stomach. In general, any food your pet is not accustomed to eating has the potential to trigger intestinal upset. Foods too rich, too fatty or too spicy can all be the culprit. For some animals, the snack you sneak can trigger a serious, life-threatening illness called pancreatitis or inflammation of the pancreas.
No Bone about this One
Even the largest and heartiest of bones can splinter and irritate the intestinal lining of your favorite pet. While most of us know that poultry bones are unsafe, knuckle bones do tend to stand to vigorous gnawing. Regardless, always, always, always supervise your dog's chewing!!
And, for those pooches who prefer to eat bones rather than just chew on them.....you guessed it.....your safest bet is to avoid bones all together!

Chocolate
With leftover Halloween candy and Thanksgiving and Christmas around the corner, many of us have more chocolate around the house than at other times. The first problem with chocolate is the fat. Remember, in the case of pancreatitis, it is the fat that causes the problem. This can lead to severe vomiting, diarrhea, dehydration and abdominal pain. In the case of chocolate toxicity, theobromine is the toxic ingredient. Theobromine can cause vomiting, diarrhea, hyperactivity, tremors, seizures and cardiac arrythmias which can be fatal. Clinical signs usually occur within 6 to 12 hours of ingestion. The more chocolate liquor there is in a prodcut, the more theobromine is present. This makes baking chocolate the worst for your pet, followed by semisweet and dark chocolate, followed by milk chocolate, followed by chocolate flavored cakes and cookies. The effects of chocolate are proportional to the amount of chocolate ingested versus your pet's body weight. Remember, it takes nearly 4 days for the chocolate to work its way out of a dog's system. If the chocolate was just eaten, call your veterinarian immediately. If is possible to induce vomiting to rid the stomach of the toxic effects of chocolate.

O Christmas Tree

The Christmas tree is full of dangers for both dogs and cats. Tinsel, along with yarn, ribbon or string is certainly an appealing play toy for any pet. When ingested, it can twist and tie up the intestines. Ornaments, too, are extremely dangerous in the mouths and stomachs of pets. The water at the base of the Christmas tree can contain secretions of fertilizer and nasty bacteria that can cause serious health problems for our pets. Light strings and electrical cords are dangerous when chewed. So, use common sense when you are decorating and make sure your pet is supervised when around these items.

One of the most important parts of winter and Holiday preventative care is knowing what to do in an event of an actual emergency. Be sure and have on hand the after-hours or emergency number for your veterinarian. Also, the ASPCA (Animal Poison Control Center has a hotline: 866-426-4435 for questions and concerns about toxins or poisons your pet many ingest.

Umbilical Hernias in Puppies

A hernia is defined as a protrusion of tissue or an organ through the wall that contains it. Hernias can occur at different locations on a dog's body. An umbilical hernia is a hernia at the umbilicus which is where the umbilical cord attached to the fetus or newborn puppy. To relate to people, your umbilicus is your belly button. Because of a genetic defect, the body wall fails to close at the site of attachment of the umbilical cord, resulting in an opening in the body wall and outpouching of the skin.

An umbilical hernia can vary in size to very small (2-3mm) or very large where a large defect or hole can be felt in the body wall. For the most part, the outpouching of skin contains fat from the abdomen. However, if the hernia is large, the outpouching can contain intestines.

This is a picture of a small umbilical hernia in a puppy. This hernia contains abdominal fat.

Most umbilical hernias are congenital which means present at birth. And, in dogs, umbilical hernias are thought to be hereditary.....meaning passed to the offspring from parent's genes. While most umbilical hernias are not life-threatening and do not cause symptoms, large defects which contain intestinal contents should be surgically repaired to prevent damage to the intestines. If the hernia is small and contains only abdominal fat, it can be surgically repaired when the pet is neutered.
Because umbilical hernias are hereditary and undesirable, puppies born with hernias should be spayed or castrated and not used for breeding.

Sweeney in Horses

Sweeney is the common name for shoulder atrophy (shrinkage or wasting) in the horse. The muscle atrophy is caused by damage to the suprascapular nerve which innervates to the infraspinatus and supraspinatus muscles. These muscles are found on the scapula or shoulder blade of the horse, on either of the spine or bony ridge of the scapula. When these muscle atrophy, the shape of the scapula becomes noticeable by the hollowing on each side of the spine of the scapula. The pictures below illustrates the loss of muscle on the shoulder blade and the distict spine of the scapula.



The nerve damage is commonly caused by horses colliding with other horses or objects.....ie stall doors, trees...etc. Nerve damage is also caused by ill fitting work collars putting pressure on the nerve. This is seen in horses which are used to pull wagons, carts and freight.


Pain may or may not be present in the affected limb. As the muscles atrophy worsens, the horse may have difficulty extending the forelimb. Also, horses may swing their shoulder out due to instability or loosening of the shoulder joint from lack of muscle and ligament tone.


Treatment of sweeney involves anti-inflammatories and physical therapy. Nerves can heal and possibly even regenerate if the injury is not too extensive and enough time is allowed. Muscle massage and electrical stimulation has been used. For cases with extensive scarring, surgery can be performed to release the nerve and hopefully regain function. In the case of a poorly fitted collar, rest and a properly adjusted collar is indicated.

The Wonderful World of Draft Horses Part II

In the last blog, I discussed some general characteristics of draft horses and the Belgian breed. This blog, I will discuss the other two major draft breeds: Percherons and Clydedales.
Percherons


The Percheron horse originated from France in the province of Le Perche, located about 50 miles southwest of Paris. Traditionally, the Percheron breed was a breed of greys. Used as a war horse, the French Knight is almost always seen on a grey or white horse. When the day of the war horse was over, Percherons were used to pull heavy stage coaches in France. These horses could trot 7-10 miles per hour with the endurance to perform day in and day out. The light colored greys and whites were easily seen at night and thus preferred. When the railroad replaced the stage coaches and horses began to replace oxen in agriculture, the need for a heavier draft horse grew. The breeders of Le Perche complied. From war horse to light draft coach to heavy draft, the Percheron breed was developed.
This picture belows show two teams in exhibition. Note the one team is a team of black Percherons and the other team is a team of greys.

Just as other European draft horses, the Percheron breed was heavily imported into the US in the 1870s and 80s. The current Percheron Horse Association of America was formed in 1905. The number of registrations grew until the 1940s and WWII. The low point in Percheron registrations came in 1954 when just 85 head were recorded. Just like the Belgian breed, a handful of breeders persisted and Americans rediscoverd the usefulness of the draft horse. Since then, the Percheron breed has seen a resurgence in its numbers and value.

While greys and dapples are still commonly seen, the Percheron breed is noted for its coal black color. The picture below is a grey Percheron mare.


Clydesdale
The Clydesdale breed originated from Scotland in the district of Lanarkshire. As with the other European draft breeds, these horses were originally developed for use in warfare to carry knights into battle. A heavier breed was needed to carry armor-clad warriors to war. When the need for war horses declined, the Clydesdale horse was bred not only for agriculture but for heavy haulage in the coalfields of Lanarkshire. The Clydesdale breed flourished in the late 19th century leading to large numbers of exports into Australia, New Zealand, Canada and the United States. Today, the Clydesdale is virtually the only draft breed in its native Scotland. The picture above is "Samurai" owned by Dr. Linda-first place gelding and 1st place American Bred Gelding at the National Clydesdale show.

The modern Clydesdale stands between 16 and 19 hands, weighing in from 1600 to 2200 pounds. The Clydesdale has a very distinctive look with its most common color being bay. A large amount of white on the face and four white stockings with the long white "feathered" legs create a vivid picture. The feather is the long silky hair on the legs that flow to the ground. Other colors in the Clydesdale breed include black and roan. The Clydesdale Breeders of the United States incorporated in 1879 to register and preserve the pedigree of the Clydesdale Breed.
So, now you know about the characteristics of the three major draft breeds: Belgians, Percherons and Clydesdales. If you are interested in seeing more of the draft breeds or perhaps even owning a draft horse, I encourage you to seek out breeders and exhibitors in your area.
More information can also be found on each of these breed registeries websites:

The Wonderful World of Draft Horses




As you can tell if you've read this blog, we are draft horse enthusiasts here at the Arthur Veterinary Clinic. I was raised with Belgians on a farm near Arcadia, Indiana. Dr. Linda breeds and shows Clydesdales and Dr. Scott and his brother, Gary (my husband) have bred and shown Clydesdales, Percherons and Belgians. The Arthur Veterinary Clinic has a large client base of draft horse owners.


August and September are busy months if you show draft horses since many state fairs in the Midwest have large draft horse shows. And, the Indiana State Fair has one of the largest. On a personal note, I have just returned from spending 15 days at the Indiana State Fair helping run the draft horse show. I am the third generation of Ellers to be on the show committee. My grandfather, my father and my brother have all been involved with the show continuously since the 1950s. And, my other brother has been an announcer and I have two nephews which also help with the show.

The five major breeds which make of draft horses are Belgians, Percherons, Clydesdales, Shires and Suffolks. I will limit this discussion to Belgians, Percherons and Clydesdales which each have their individual breed registries. This blog will focus on Belgians and I will follow up with Percherons and Clydesdales on the next blog.

The draft breeds originated from Europe. They are known for their gentle disposition and drafty size which allows them to excel at farm work, pull large wagons and freight. With the advent of mechanization after World War II and the introduction of the small, rubber tired tractor, the draft breed numbers declined significantly. However, over the decades, long time breeders have persisted despite the use of tractors. Other equine lovers discovered the usefulness of the draft horse, using them on non-farm tasks. Horse shows and state fairs began to welcome the gentle giants and the draft horse industry has continued to flourish. Artificial insemination, cooled transported semen and embryo transfer are used frequently in draft horse breeding.
While the majority of draft horses are located in the Midwest and east central Canada, they are popular throughout the US. A major driving force behind the draft horse industry are the draft horse shows. A draft horse show usually consists of two parts: the halter or conformation classes for purebred draft horses and the hitch or performance classes. Most large shows have separate classes for each breed while the smaller shows and county fairs may combine all breeds in a class.

Halter classes are shown by age....for example, all the yearling mares will compete against each other. Typically, the show will crown a junior champion stallion and mare (2 years and under) and a senior champion stallion and mare (3 years and over). From these winners a Grand Champion mare and a Grand Champion stallion will be awarded. Most shows then go on to choose a Best of Breed.

Hitch classes involved horses in harness pulling either a show cart or a wagon. A show cart is usually pulled by one horse, whereas the classes pulling a wagon are teams, unicorns (three horses), four and six. Occasionally, an event will host an eight horse hitch class. Over the years, geldings have been commonly used in the hitch classes. However, the last 10-15 years has seen an increase in the number of all mare hitches which has resulted in separate classes for gelding hitches and mare hitches. If you have never been to a draft horse show, I encourage you to attend a hitch show. Watching these hitches thunder around a ring, decked out in show harness and a show wagon will give you goose bumps.....I guarantee it!!!

Belgians
The Belgian horse originated from the country of Belgium. Belgians are typically sorrel colored with a light or white mane and tail, varying amounts of white on their legs and a stripe on their forehead. They can also be blonde or chestnut. Today's Belgian is a big, powerful horse that retains the drafty middle, a deep, strong foot, a lot of bone, the heavy muscling and amiable disposition possessed by the early Belgians. His qualities as an easy keeper and a willing worker make the Belgian a favorite. The modern Belgian possesses an animated gait and hitch horses must be up headed and high stepping. At this time, Belgians outnumber all the other draft breeds combined.

The is a picture of Dr. Scott and Gary showing the first place aged yeld mare at the NABC VI. Notice that Dr. Scott is on the lead and Gary is the whipman. When the horse is lead before the judge in a halter class, the whipman trails the horse. In this picture, he is seen in front of the horse to help with the headset when standing before the judge. In halter classes, mares have their tails tied up but not their manes braided. Stallions and geldings have their tails tied up and their manes braided with rosettes. Mares manes are braided for hitch classes.

Mites, Mange and Creepy Crawly Things

When we refer to "mange" in dogs and cats, we are usually referring a mite infestation of the skin. The two most common skin mites found in dogs are Demodex canis (canine demodicosis) and Sarcoptes scabiei (canine scabies). I am going to limit this blog to these two types of mites.

Canine Demodicosis
Demodex mites live and fed in the hair follicle and oil glands of the skin. Many dogs have small numbers of Demodex mites in their skin without causing any problems or clinical signs. Demodex mites can cause clinical signs when the host dog is immunocompromised and the mites can reproduce into large numbers. Clinically, demodicosis can present in two form: localized and generalized.
Localized demodicosis occurs in dogs less then two years of age who show signs of irregularly shaped, mildly irritated areas of hairloss. For the most part, the skin is usually not inflammed and only mildly pruritic (itchy). Many cases of localized demodicosis will resolve spontaneously without treatment. Prognosis for this form is good. In contrast, generalized demodicosis is a severe disease. Dogs with the generalized form usually have secondary bacterial infections with systemic disease including lymphadenopathy (enlarged lymph nodes), lethargy, fever and cellulitis. Generalized demodicosis is usually seen in adult dogs with an underlying immune or systemic disease. The underlying disease must be diagnosed for treatment to be effective. Unfortunately, these cases can be difficult to cure.

For the most part, Demodex mites are not considered contagious. However, if a mother has Demodex mites present on her skin, the mites can invade the newborn puppy immediately after birth. If the pup has a normal, healthy immune system, the pup should be able to eliminate the mites. Because of this, young dogs showing clinical signs of demodicosis may have a hereditary predisposition for demodicosis and should not be used for breeding.
Diagnosis
Diagnosis of canine demodicosis is made by perfoming a skin scraping on the affected areas and identifying the demodex mite under a microscrope. This is a picture of a demodex mite.
Note the elongated, cigar-shaped mite with eight legs. Demodicosis is rare in cats but can occur.
Treatment
Canine demodicosis has been successfully treated with whole body dips. Some of these dips are no longer on the market. Oral ivermectin is successful in treating demodectic mange but should be used cautiously and under the supervision of a veterinarian. Antiparasitic therapy must be continued for 2 consecutive negative skin scrapings.
Canine Scabies
In contrast to Demodex mites, Sarcoptes mites are highly contagious by direct contact between dogs. These mites burrow tunnels into the skin to lay eggs, causing intense pruritis (itching), inflammation and hairloss. The Sarcoptes mite is round, without a distinctive head and they have four pairs of short legs. Sarcoptic mites can infest people causing intense pruritis in pet owners!Dogs with Sarcoptic mites may have raised papules on their skin which develop into thick crusts. Secondary bacterial and yeast infections may result leading to chronic, generalized disease with severe skin thickening if left untreated.

Here is a picture of a dog with Sarcoptic mites. Note the reddened, scabby appearance of the skin especially on the pinna (ear flap) of the ears. Sarcoptic mites commonly inhabit the ear flaps of affected dogs.
This pup was very itchy!

Diagnosis
Unlike Demodex mites, Sarcoptic mites can be difficult to diagnose from a skin scraping. These mites can be elusive leading to misdiagnosis. Treatment for Sarcoptic mites should be instituted if the history and clinical signs are suggestive.
Treatment
As with canine demodicosis, Sarcoptic mange can be treated successfully with parasitical whole body dips. Oral ivermectin is also successful in treating Sarcoptic mites but should be used cautiously and under the supervision of a veterinarian. A topical parasitical, called Revolution, is approved for the treatment of Sarcoptic mites. Secondary bacterial and yeast infections must also be treated.
So, now you know the difference between the common skin mites that cause mange in dogs. If you are like me, just the thought of these little guys make me itch!
