Glen of Imaal Terrier vs American Mastiff - Breed Comparison

Hailing from Ireland and known also as the Wicklow Terrier or just Glen, the Glen of Imaal Terrier was used to get rid of rats, badgers and otters as well as being a good all-round farm dog.

Using his strength, he was good at digging into burrows to root out badgers, but unlike other terriers, he wouldn’t go on and on yapping around his prey. He isn’t an excessive barker.

The terrier was recognised by the Irish Kennel Club in 1934 and later by the American Kennel Club in 2004. The Canadian Kennel Club recognized Glens in 2017.

The history of the American Mastiff is entirely tied to the old European Mastiffs but in particular the English Mastiff. The developers of the American Mastiff crossed the English Mastiff with the Anatolian Mastiff at the Ohio kennel, Flying W Farms. The founder of this breed is Fredricka Wagner. Because of this the English Mastiff and the American Mastiff look very much alike. The difference between the two is that the American Mastiff was bred to have less health concerns than the English Mastiff and without the drooling. In 2000 the CKC acknowledged that the American Mastiff and the English Mastiff were separate breeds.

An interesting fact with the Glen of Imaal Terrier is that this is a dwarf breed, being a big sized dog on short legs, with the front feet turning out.

A typical Glen of Imaal Terrier stands at roughly 30 – 36cm and weighs up to about 16kg. Another interesting aspect with this dog is that it can take up to 4 years to reach maturity.

The head of this muscular dog is large, the ears are half erect, and while the tail has always been traditionally docked, it is often left long. The double coat of the dog is soft with the undercoat but he has a wiry outercoat. The color of the coat is essentially wheaten, tan or blue. The coat doesn’t shed much but some Glen owners strip excess hair a few times during the years.

Temperament:

Glen of Imaal terriers are energetic, easygoing and they make splendid pets for any family. He is more than happy to give up lying around for games and activity just to lie at his owner’s feet. He is an intelligent dog too and even though he is somewhat stubborn, he responds well to training and socialization. In fact training and socialization is important for every dog breed to prevent negative behavior and to ensure your pet is obedient.

This crossing of the English Mastiff and the Anatolian Mastiff resulted in a Mastiff with a much drier, less drooling mouth than the other Mastiffs. This is a giant, massive dog – powerful and muscular. With a wide head that is rectangular rather than square. Their eyes are dark amber, and their ears are high on their head and rounded. With a medium size muzzle, black mask and heavy head, the American Mastiff is a handsome dog.

Their chest is broad, deep with ribs that extended backward. He has strong legs that are parallel and wide set. He also has a long tail. Puppies of the American Mastiff are born almost black and as they grow their coat color lightens. In addition, it is important that they have a wrinkled forehead as well and a scissors bite is preferred.

The Glen of Ismaal Terrier is more docile than other terrier breeds, but that doesn’t mean he isn’t feisty. He loves to play and is an adventurous dog, always on the lookout for exciting opportunities and to chase prey.

He is a good natured pet and he gets on well with adults, children and pets in the home. He can adapt well to life in the city or in the countryside so long as he is with his family members.

He isn’t a couch potato dog though, and wherever he lives, he will need a good amount of exercising. Treat him with the love and respect he craves, and you’ll have a wonderful canine companion.

A love of children and devotion to his pack (family) is bred into the American Mastiff. He is non-aggressive unless you threaten his family or his children. Then he becomes courageous, protective and defensive. This is a gentle giant most of the time, however due to size and the need for strong leadership, the American Mastiff should be socialized and trained early. If they are socialized and trained they will be calm, gentle dogs. They will remain protective and alert, but they will be friendly with strangers. They love to please their people and being highly intelligent they learn fast.

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.

American Mastiffs seem to have fewer health issues than other larger giant breed dogs. However, they can experience allergies as many large, wrinkled dogs do. They also might have a tendency toward eye issues, hip dysplasia, cancer and heart disease. Bloat might be the most life-threatening issue many American Mastiffs experience.

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.

Make sure he always has a bowl of fresh, cool drinking water.

Giant breeds like the American Mastiff are known for growing rapidly as a puppy and therefore proper feeding and nutrition is essential. The slower your American Mastiff grows, the better. Make sure your puppies get enough phosphorous and calcium in their high calorie diet. Free feeding is not recommended. Feed puppies up to 4 small meals per day and feed adults twice a day.

Health issues

As previously mentioned this breed is a fairly healthy one, There, are however, certain evaluations you should do with your American Mastiff puppy to be sure she is in good health. These tests would include an elbow and hip evaluation to check for dysplasia. He should have an ophthalmologist and cardiologist examine him as well. Most American Mastiffs will not have any problems, but these evaluations will help to prepare you if they do. The wrinkles in your dogs; face, around the eyes and muzzle must be kept clean as they can become infected if you don’t.

Exercise and games

Unlike the way he looks, the American Mastiff is not a couch potato, but neither are they a high energy, exercise machine. They do well living in apartments or homes, with or without a fenced in yard. They need a long walk every day. They need mental stimulation through exercise and games. Make sure they learn to love to play so that they don’t become lazy as they age.
