Years ago, I lost my own personal pit bull to a fast growing brain tumor. Unfortunately, in both human and veterinary medicine, brain tumors can result for no known reason. While genetics and environment may potentially have a role, the underlying cause for brain tumors is typically unknown.
The Havanese does not have to be really light. Depending on the size of a Havanese the weight ranges from 7-22lbs. I own a very athletic agility Havanese that stands 11â³ at the withers. She weighs 18-20lbs depending on how much training she does and her muscle mass. From the AKC Standard.
The coat is smooth and clings tightly to the body giving the dog a streamlined appearance. The dogs stand 36 to 41 cm (14 to 16 in) at the withers and weigh 13 to 17 kg (29 to 37 lb) for males; females are 11 to 15.4 kg (24 to 34 lb). The coat is smooth and clings tightly to the body giving the dog a streamlined appearance. The lips show no looseness. Liver-coloured, black and tan dogs can occur but are rare.
