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.
Havanese, as adults, are going to be somewhere between 7 and 13 pounds, according to AKC standard. We breed our Havanese puppies to be medium to small in size. AKC standard requires 8-12 pounds as adults, we keep our Havanese at about 9 pounds. They are 10 inches tall at the withers, also in accordance to AKC standard.
