Bacterial and Viral Infections:

Diseases such as rabies and parvo can be prevented by means of vaccine.

Parasites:

Your dog can be infected with all kinds of worms and bugs such as ticks d and fleas as well as mites. Some of these parasites can be transmitted to you. Your vet can talk about preventive medication.

Bloat:

Gastric Dilatation and Volvulus, commonly referred to as bloat often occurs in dogs with deep chests.

The stomach twists and fills with gas,and blood to the stomach is cut off. Left unattended to, your dog can die, sometimes within half an hour. His stomach is hard and swollen, requiring immediate veterinary attention.

Your Parson Jack Russell can live to be between 12 and 15 years but nonetheless he does have some breed-related health issues to watch for.

Eye Disorders:

Eye conditions which can affect this dog include primary lens luxation,cataracts, corneal dystrophy and progressive retinal atrophy. With cataracts the lens of the eye develops a cloudy look resulting in poorer vision and sometimes blindness. Cataract surgery is available for dogs.

Obesity:

Your Parson Jack Russel should be lean and muscular and always full of energy. Avoid feeding him unhealthy treats which can lead to obesity and other health problems.

Parasites:

All kinds of parasites such as ticks, fleas and worms can invade your dog’s body. Roundworms, hookworms and tapeworms can cause havoc with their health and some of these parasites can even be transmitted to humans. It’s why it is important to get your puppy to the vet to be de-wormed and to get his first injections.

Liver Problems:

A liver disorder known as portosystemic shunt can mean that some of the blood supply doesn’t get to the liver and it doesn’t function properly. This will mean the liver can’t remove toxins from the bloodstream effectively.

Spay or Neuter:

Have your pet spayed or neutered if you don’t want puppies. Spaying or neutering also decreases the likelihood of certain types of cancers.

Diet:

Nothing but a top quality diet is good enough for your pet. Commercially manufactured dog foods are a convenient means to feed your pet, and there are some excellent brands.

Look out for the ones for extra large dogs and avoid the ones with low quality ingredients. The dry kibble you give your big pet can be made more tasty when you add some homemade food to it about twice a week.

Dogs thrive on simplicity, so boiled chicken, sweet potatoes, brown rice or pasta, carrots and spinach will be wonderful for him when you chop the food up and add it into the dry kibble. Its such a tasty, wholesome treat for your pet.

Some raw meat added in occasionally will contribute to your pet’s heath. Make sure he is never without a constant supply of fresh, cool water.

Grooming:

Brush his coat at least twice a week. Check inside his ears for redness which could indicate an ear infection.

He’s an intelligent pet with lots of energy, so you will need to keep his mind and body active by ensuring he enjoys walks every day. He isn’t a dog that requires running with you on your jogs or cycles.

The Parson Russell Terrier has different coat types – the smooth and rough and both will require regular brushing. Rough coats will require plucking or clipping to avoid matting.

Check his eyes and ears regularly. Look inside his ears for excess wax and dirt which could lead to an ear infection. His nails should also be trimmed.

No Puppies – Spay or Neuter:

The best thing you can do for your Parson Russell Terrier if you don’t want your pet producing puppies is to have it spayed or neutered. Spaying for females or neutering for males decreases the likelihood of certain types of cancers too so it can be beneficial.

Diet:

Diet is hugely important for a Parson Russell Terrier and the food you decide for him can impact his health. Many time those ‘treats’ you feed your pet do nothing more but give him a stomach ache.

It's tempting to pop chocolates, popcorn, nuts and ice cream into your pets mouth when he is so adorable but in the long run it is shortening his life. All he basically requires and needs is a simple, consistent diet of the top commercially manufactured foods mixed with some tasty home made food from time to time.

Boiled chicken, brown rice and vegetables such as sweet potatoes, carrots and spinach will do your pet wonders. Ensure he always has fresh, cool water available to him.
