Jack Russell terriers are generally a healthy breed that can live up to 14 years of age, but still every dog is prone to the more common dog problems such as hip dysplasia, bloat, ear infections and dental disease among others.

If your Irish Jack Russell is in pain, he is lethargic and sick, don’t delay – take him to the vet right away.

The Cao Fila de Sao Miguel is a dog who enjoys exceptional health. When you do research you see there aren’t really any particular illnesses plaguing this dog, and he can actually live to be 15 years of age. Be aware of some illnesses as they are common among different dog breeds – hip- and elbow dysplasia, bloat, eye diseases such as progressive retinal atrophy and cataracts, heat intolerance and arthritis.

Dog bloat:

This is a dangerous illness that can affect any dog – small or large. This is when the dog’s stomach fills with fluid or gas so that it expands. The stomach then puts pressure on other organs and your dog can have trouble breathing. There is also no blood flow to the heart. Sometimes the stomach of the dog twists and your pet can go into a state of shock. Recognize the symptoms of bloat – a swollen stomach, drooling and wanting to vomit but nothing coming up. Get your dog to the vet immediately.

Abscess:

An abscess can be so painful for your pet often when your dog has a thick coat it could go undetected. If an abscess on your pet doesn’t burst, or even if another abscess appears, a vet must be consulted and a course of antibiotics given.

Ear Infections:

Ear mites, dirt and a build up of wax may cause your dog to scratch at the ear, shake his head or hold it on one side. There may even be a foul-smelling discharge. Your dog will need to have his ears cleaned. Special ear drops can rectify the problem. Remember that hot, red ears will require veterinary attention.

Grooming:

The Irish Jack Russell is an average shedder with his short or longish coat which is easy to groom, requiring a brush once or twice a week. His nails grow quickly too and they can get caught on something and cause him damage. Trim your pet’s nails to prevent this.

Diet:

Feed your Irish Jack Russell good quality dog food each day. If you feed him commercially manufactured dog food, be certain to check the feeding instructions on the packaging.

He is a small dog, and overfeeding can be just as bad as under-feeding. It’s never a good idea to just go on and on feeding your pet dry or wet kibble day after day. Add in some cooked chicken, rice, pasta and vegetables as a treat and to also provide some variety for him.

Also a little bit of raw meat occasionally can do him the world of good and you’ll see the appreciation in his bright eyes and wagging tail.

Add in some home-made vegetables, rice and meat every now and then. The idea is to make sure your dog is getting in all the minerals and vitamins he needs.

There is evidence showing that dogs who enjoy raw meat every now and then enjoy a number of health benefits. Skin and teeth are improved, your dog has a shinier coat, less allergies,less inflammation and he is more relaxed and amicable. Ensure a constant supply of fresh, cool water in a clean bowl and at all times.
