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 first Shiba Inu was imported into the United States in 1954 and was recognized by their Kennel Club in the Miscellaneous Class and also the Non-Sporting Group.

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.

Simply add into one big pot chicken, brown rice or pasta and spinach, sweet potatoes and carrots. This food can all be chopped up, refrigerated and added warmed up and in small portions to your pets dry kibble once or twice a week.
Try and also give him some raw meat occasionally. Ensure that there is always a bowl of fresh, cool water within his reach.
