Mastiff Health

The Mastiff Club of America (MCOA) provides in-depth information on breed health. Responsible breeders screen their stock for health conditions such as seasonal allergies, eye anomalies, heart disease, cancer, eye and hip dysplasia, von Willebrand's disease, degenerative myelopathy, and epilepsy. Hygromas'¿harmless natural 'cushions' that protect the elbow joints when the Mastiff is lying on hard surfaces'¿are common. Do not allow the vet to drain them. Finally, Mastiffs can experience bloat, a life-threatening condition where the stomach suddenly distends and often twists as well. Owners should educate themselves as to what symptoms indicate this is occurring and what to do should it occur.

About the Mastiff

The colossal Mastiff belongs to a canine clan as ancient as civilization itself. A massive, heavy-boned dog of courage and prodigious strength, the Mastiff is docile and dignified but also a formidable protector of those they hold dear.

For the uninitiated, a face-to-face encounter with these black-masked giants can be startling. A male stands at least 30 inches at the shoulder and can outweigh many a full-grown man. The rectangular body is deep and thickly muscled, covered by a short double coat of fawn, apricot, or brindle stripes. The head is broad and massive, and a wrinkled forehead accentuates an alert, kindly expression. Mastiffs are patient, lovable companions and guardians who take best to gentle training. Eternally loyal Mastiffs are protective of family, and a natural wariness of strangers makes early training and socialization essential. Mastiffs are magnificent pets, but acquiring a powerful giant-breed dog is commitment not to be taken lightly.
