Interesting Facts : Ticks And Diseases Caused by Them in Dogs

Ticks, fleas and mites are the most common external parasites found on the body of dogs. However,  ticks are perhaps the most notorious of the three as they are responsible for causing a number of debilitating diseases.  

Actually, ticks kind of lay an ambush hiding in vegetation waiting for prospective hosts to pass by whereupon guided by their body heat, they attach themselves to the body. Thereafter, the tick utilizes its specialized mouth parts to pierce the skin and starts its blood meal.

A tick does not detach itself till its meal is complete. Apart from being blood suckers, ticks are also responsible for transmitting a large number of diseases to their hosts. Interestingly, these diseases are caused by other microbes and not by ticks themselves. As a matter of fact, the ticks harbour these microbes and transmit it to the host. That is why the ticks are referred to as vectors of various diseases.

2.	Brown Dog Tick (Rhipicephalus sanguineus)	Vector for 02 diseases viz. Ehrlichiosis – caused by an organism called Ehrlichia & Babesiosis – caused by an organism called Babesia	Yes (for both diseases)

COPING WITH CANINE PANCREATITIS

If your dog is suffering from marked loss of appetite, vomition, diarrhoea, fever, lethargy, dehydration and has a painful abdomen, it might be suffering from Pancreatitis. 

The pancreas is an inverted “V” shaped, pink colored glandular structure located just below the stomach adjacent to the duodenum. Duodenum is a part of the small intestine. The Pancreas has two functions. Firstly, it secretes insulin and glucagon – hormones that are responsible for sugar metabolism in the body. An abnormality in this function leads to Diabetes mellitus. Secondly, the pancreas also secretes digestive enzymes (amylase, protease, lipase) through an opening in the duodenum where in partially digested food coming down from the stomach is further digested with the help of these enzymes.

Simply put, an inflammation of the pancreas is referred to as Pancreatitis. In this condition, the pancreas greatly swells up and the mechanism by which these digestive enzymes normally get liberated in a calibrated way gets disturbed and these enzymes start destroying the pancreatic cells. This triggers a vicious cycle and the cascading effect goes on. In severe cases, the kidneys and liver may also get affected. Thus the disease progresses and if timely remedial measures are not instituted it may lead to shock and death.   

  

Causes

Trauma due to accidents, post – surgery, tumours, certain medicines (chemotherapy agents, antibiotics, anti- epileptics), high fat, low carb diet, sudden gorging on high fat diet, obesity etc are often attributed to Canine Pancreatitis. Breeds like Miniature Schnauzer, Miniature Poodle are more predisposed to the ailment.

Diagnosis

Traditionally, diagnosis is based on the clinical signs and by measuring the levels of two enzymes viz amylase and the lipase in the serum. Higher levels are suggestive of Pancreatitis. However, it is worth noting that the levels of these enzymes will also be found high in conditions other than Pancreatitis viz kidney diseases, prolonged use of corticosteroids etc.  

To circumvent this problem a new approach is to measure the level of pancreas specific lipase. Pancreas specific lipase, as the name suggests, is an enzyme that is only secreted by the pancreas and the detection of it in the serum or the blood confirms that that the pancreas specific lipase has been leaked by the pancreas. This test is referred to Specific Canine Pancreatitis Lipase Test and today is the most definitive diagnosis of Canine Pancreatitis. It is a rapid test and results can be obtained within 10 minutes.  However, other techniques like Ultrasound and X-rays are also employed with varying success.

Treatment

The approach towards the treatment is primarily symptomatic. Generally, in cases where the vomition is very severe, feed and water are not offered to the dog for 24 -48 hours. Instead, the dog is administered intravenous fluid to negate dehydration, meet energy requirements, facilitate blood circulation. Anti vomition drug, appropriate pain killers are also administered intravenously / intra muscularly to make the dog comfortable and manage the vomition. The traditional approach towards withholding the feed and water orally is primarily aimed towards making the irritated digestive system settle down.

When the feeding eventually commences, care should be taken to offer a fat free or a low fat diet. As a matter of fact, it is actually advisable to manage the dog on a fat free diet for its life to prevent re-occurrence of the condition. 

7 TIPS FOR ENSURING A COMFY TIME FOR YOUR DOG THIS WINTER

It’s that time of the year when the days are becoming chillier and there is  just a  hint of fog in the mornings and late nights. Indeed, your woolens have started coming out! However, are your things in place so that your pooch has a comfy time this winter? Here are seven tips that will help you take care of your dog this winter.

1.         Preliminary Check up

Schedule an appointment with your vet especially if you have an old dog at home. He will examine the dog for arthritis and other ailments and suggest what needs to be done. Remember that dogs with long hair and furry coats fare better in winters as compared to their small haired cousins.

2.         Sort out the Sleeping arrangements

Ensure that there is a rug, a small dog – bed, suitable bedding available for your dog especially during the night when the temperature dips sharply. The extent of sleeping arrangements made for the dog should be in consonance with the severity of the winter.  In no case, the dog should be allowed to sleep on the floor as it will not only be uncomfortable for the dog but may also predispose it to other ailments.  The dog’s bed should be carefully placed so that it is not exposed to wind / draft.

3.         Watch the calories intake  

In winters, a dog spends more energy in keeping itself warm. It is therefore a good idea to increase the quantity of feed just a little during the winters to enable it to compensate for the energy loss. However, take care that your dog doesn’t become overweight. 

4.         Walking the dog

After walking the dog, wipe the paws clean and ensure that there is no moisture or dirt in between the toes as these predispose the dog to pododermatitis – a painful skin infection. Remember, that the grass is wet in winters and the moisture and the dirt rapidly lead to pododermatitis. Applying a bit of Vaseline on the paws before commencing the walk and after cleaning the paws subsequent to the walk is a good idea to keep the paws healthy. 

5.         Invest in a Dog Coat

Buy a dog coat of the correct size and a nice color. Gradually, make your dog acquainted with it by making it wear for small periods of time. Slowly, it will get accustomed to it and actually start enjoying wearing it. Besides, a  dog with a smart coat at heels walking with its dashing owner is a wonderful sight on wintry mornings and can bring a smile on the most reticent souls in your block.  

6.         Beware of the heating arrangements  

Take adequate precautions that the dog doesn’t come to any harm due to the fireplace, electric / kerosene heaters and the quaint little bukharis still very much in vogue in the quaint little hilly towns of India.

7.         Monitor the water intake  

Often indoor heating arrangements make our premises extremely dry and lower the humidity to such a level that the dog may become dehydrated. Ensure that your pooch has easy access to clean drinking water at all times.

Implement these tips and be assured of a great time this winter with your healthy and happy dog!
