The Bullmastiff is a cross between the English Mastiff and Bulldog. Mastiffs are calm and laid back, while the Bullmastiff is a more active dog. There are differences in temperament as well—the Bulldog's temperament is more apparent in the Bullmastiff. While there are similarities in appearance between the breeds, the Mastiff is larger than the Bullmastiff and each has distinctive features.
Occasionally, a Mastiff may suffer from pica, an eating disorder that causes dogs to eat rocks and stones, clothing, feces (also called coprophagia), and other dangerous non-food items. Pica is not limited to Mastiffs. While puppies may grow out of the behavior, sudden onset pica in adult dogs may be related to malnutrition, thyroid disease, vitamin deficiency, or other health concerns. Behavior-related causes like boredom or anxiety may also be to blame.
Do not allow a dog showing signs of pica to chew or eat the items it is drawn to, but do consult your veterinarian, who will recommend the appropriate next steps; these may include a change in diet, an increase in portions, activities to distract the dog from the behavior, or medication. Ingesting non-food items such as stones and clothing can result in dangerous, expensive intestinal blockages or death.
Yes, Mastiffs drool—a lot. The pendulous lips and skin around the English Mastiff's mouth make for a drooly canine. Drool happens in anticipation of dinner, with thirst, in hot weather, due to excitement, or 'just because.' Many Mastiff owners keep designated drool towels throughout the house to wipe up the inevitable slimy messes. While drool is a normal part of befriending a large, loose-lipped dog, there is such a thing as too much drool. An increase in drooling may be due to anxiety, upset stomach, or a medical concern that needs veterinary attention.
