Pyrenean Mastiff vs Glen of Imaal Terrier - Breed Comparison

This is a fairly healthy dog breed, particularly when you consider what a big dog he is. There are always some health concerns to watch for so that you can take steps to get your pet well again.

Dental Disease:

There is tartar build-up on the teeth and this can lead to infection of the gums and roots of the teeth. Rotting teeth can cause pain, but more worrisome they can cause damage to the heart and kidneys as well as the dog's joints. The vet or professional pet groomers can keep your pet’s teeth clean. They can advise you on how to take care of your large pet’s teeth.

Bacterial and Viral Infections:

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

Obesity:

You can’t afford for a big dog like this to become obese. It’s a serious disease and can put pressure on your dog’s joints and also cause back pain and digestive disorders.

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.

The Glen of Imaal Terrier is a feisty, healthy breed, particularly when he gets the best food there is, then he is not likely to get ill easily.

However, just like other dogs, he can be prone to certain health conditions such as hip dysplasia. When a dog is diagnosed with hip dysplasia, the socket part of the joint is poorly developed, so that is causes abnormal friction.

Inflammation and pain can be the result and your dog can become lame. Unfortunately, rapid weight gain with puppies can put more stress on the hips, and diets without the right balance of vitamins and minerals can be bad for good bone development.

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.

Caring for a Glen of Imaal isn’t going to be a huge job. This is what makes him such a wonderful pet as he is a straightforward pet, requiring little more than a brush to avoid the hair matting.

Check his ears, teeth and nails from time to time to ensure he is always in tip top condition.

Diet:

If you intend making use of the convenience of commercially manufactured dog foods, the top quality one will provide you with balanced nutrition for your Glen and you can mix in some cooked brown rice, vegetables and chicken from time to time.

The Glen of Imaal Terrier is a small-breed dog and, he should be offered dog food that has been specially formulated for small, energetic dog breeds. You can also add in a little bit of raw meat into his kibble as a treat as this is important for keeping him free of skin allergies.
