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 Field Spaniel was developed to retrieve game, being developed in 19th century England as a hunting companion. Today they are still used as hunting dogs but he is essentially a family companion and show dog.
He was developed to be a medium-sized, all-black dog. Until 1901, spaniels were divided by weight, with the Field Spaniel being the bigger dog.With developing the breed, the Basset Hound was introduced and then English Springer Spaniels were also brought into the mix.
Today the Field Spaniel is still a rare breed even in the UK. To promote the breed, the dog has been registered as a Vulnerable Native Breed by the Kennel Club.
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 Field Spaniel is a medium sized dog, standing at 43–46cm in height and weighing between 18–25kg. The single coat of the Field Spaniel is fairly long with the traditional feathering at the legs, belly, chest and tail.
The coat comes in solid colours of black, liver or roan. You might also find some ticked markings of white. The tail of the Field Spaniel is traditionally docked with the ears being long and floppy.
Happy, busy and active, the Field Spaniel makes an excellent family pet. They get on well with children and with other pets in the home. It is the kind of dog, that while friendly with all members of his human family, he forms a strong bond with one member whom he regards as special.
Bright and intelligent, he is also a dog that does well when socialized and trained, being more docile and less excitable than Cocker spaniels. The Field Spaniel is a dog who thrives on being busy and won’t relish lying around with nothing to do. He loves water and where there is a dam or pond, he’ll be there and want you to join him.
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.
Once people have owned any of the Spaniel breeds, they discover what a wonderful friend the dog is. He is loyal, loving, protective, brave, confident, fun-loving and smart. He isn’t aggressive but he may not like a stranger to reach out and pat him.
The Field Spaniel is a wonderful dog and he will adapt to life in the city or in the countryside, just so long as he has his beloved human family close by.
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.
The Field Spaniel is a robust dog breed and can live to be 12 – 14 years of age. Apart from watching for ear infections with his long ears, there are some common dog illnesses that are worth knowing about -
Most older dogs have hardening of the lens and this is when the lens turns a whitish or greyish colour. However if your dog has cloudy eyes, it doesn’t simply mean he can’t see well as he often can. Once a lens has a cataract, some people try nutritional support of the lens which can work to lessen the severity of developing cataracts.
Surgery can help but a veterinary ophthalmologist can determine if cataract surgery is needed as most times it isn’t. If you can’t afford surgery, it is still important to have your dog evaluated by a veterinary ophthalmologist so that you avoid further complications with your pet’s eyes.
Progressive Retinal Atrophy is another eye disease, a degenerative disease that affects the photo-receptor cells where they deteriorate over time and can eventually lead to blindness in the affected dog.
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.
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.
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.
The Field Spaniel has medium-length to long hair and to avoid matting of the hair, the coat will need to be brushed a least twice a week. Many Spaniel owners take their pets to professional groomers to get the coat and ears trimmed.
Check your Spaniels ears inside and out regularly, because loving water the way he does, the ears inside can remain damp and become a breeding spot for infection.
Remember to also check your Field Spaniel’s teeth as dental disease can be the root cause of many diseases.
Your Field Spaniel is an active breed and you want to be sure to feed him a high-quality commercially manufactured dog food which has been formulated for his activity level. Every now and again mix in some cooked brown rice, vegetables and chicken and also add in a bit of raw meat from time to time. Ensure cool, fresh water is always available.
