Greyhound vs American Mastiff - Breed Comparison | Petzlover

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.

The Greyhound belongs to a group of dogs known as sighthounds. This is an ancient sighthound breed dating back a few thousands years.

The dog has been bred for racing but today is also a popular pet. They’ve also been used for hunting too because of their keen eyesight and sense of smell.

In the United States there are Greyhounds registered with the American Kennel Club as well as those registered with the National Greyhound Association.

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 Greyhound is a tall, muscled, long-legged, slender dog with a flexible spine, a deep chest and exceptional eye sight.

The Males are usually about 71 to 76 cm in height with the females being slightly smaller. The dogs weigh in the region of 27 to 40 kg. The coat of the dog is short and smooth and is found in an assortment of colors, from fawn to white, tan, black and brindle.As far as grooming goes, he is looked upon as a low maintenance breed.

He has a long narrow muzzle, semi-erect/semi-floppy short ears and a long slender tail.

Sometimes referred to as being hypoallergenic, you need to allow your Greyhound indoors as the dog doesn't have an undercoat. He is therefore more susceptible to extreme temperatures. The face is long, narrow and pointed, the ears short and half-erect-half-floppy with a long, thin, whip-like tail.

Temperament:

Intelligent and gentle, the Greyhound is described by those who have owned them as wonderful pet. They are somewhat aloof around strangers but love their own human family. This is a non-aggressive, gentle, docile, calm dog. They are loving and get on well with their entire family, whether human beings or pets.

They’re sensitive dogs who appreciate quiet, calm environments. They may be quiet, but they are still social, loving the company of their family. They’re not great barkers and because they are non-aggressive, they don’t make wonderful guard dogs.

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 Greyhound, forgetting about the racing part, makes a superb pet too. He won't do well in a household where there are screaming, noisy children and adults as he wants a quiet home to live in.

He can get on well with kind, gentle, respectful children as well as with pets in the home. Just like any dog, he will also need training and socialization as this can build up his confidence and then he knows how to please his owners and what they expect.

The Greyhound will require a gentle, fair, kind owner who understands his need for peace and quiet, and then he becomes a most wonderful devoted, loyal and loving pet.

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.

Greyhounds are a wonderfully healthy dog breed and with good care can reach 14 years of age. They aren't prone to many genetic illnesses and unlike so many other dog breeds, this is one dog that doesn't battle with hip dysplasia – in fact it is almost unknown among this tall, slim dog breed.

The Greyhound does however, have a deep chest and this is what makes him vulnerable to bloat or gastric torsion. You have to take action quickly if you detect bloat – the stomach swells up – as this is a life-threatening condition that can occur quickly when air is trapped in the stomach. The stomach can become twisted.

Make sure your Greyhound doesn't gobble his food too quickly and preferably give him smaller meals as opposed to one or two large bowls of food.

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.

Diet:

Your Greyhound’s breeder will be the best guide for the type of- and the amount of dog food your hound will need. Of course, a growing puppy has different nutritional needs from a mature or senior Greyhound.

Growing puppies and young dogs use a lot of energy so they will require a diet rich in protein. According to Greyhound experts, an adult Greyhound dog will need an average daily caloric intake of 1740 calories.

Older dogs and those that have been spayed or neutered will need less. Apart from the very best quality kibble, your Greyhound will most certainly require raw meat from time to time. You can also give him some cooked chicken, vegetables and brown rice. He should have access to a constant supply of fresh, cool water.

Grooming:

The Greyhound's coat is smooth and short and he sheds very little so he will only need a gentle brush-down once or twice a week.

Exercise:

Having a relaxed lifestyle is what your Greyhound will love. He is a dog that needs to spend time indoors. When outdoors, whether you live in the city or the country, he will need daily walks and a run in the park regularly.

Just because he is a sprinter, it isn't wise to take him with you with cycling or jogging as he is geared for a short burst of speed as opposed to a long run.
