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 Havanese is a toy dog It is smart and can be easily trained. It is best to train this dog at a young age, because some habits will stick as they become older. However, training these dogs while they are older is still possible.lthough the Havanese is an active and lively dog, they are small enough that many of their exercise needs can be met in a house or yard, and therefore they do not require as much vigorous exercise as other breeds may.
