We were proud owners of a BEAUTIFUL Berner, unfortunately the breeder that sold him to us bred the lines to closely and he was diagnosed with hip dysplasia (sp) when he was only 6 months old. He was constantly in pain even though he was on meds, since he was young surgery was not an option. He couldn't even get up and walk, I had to help him up and help him with the bathroom. After talking to the Bernese Mountain Dog club here in Illinois, and many conversations with the vet, we decided with a heavy heart to end his suffering. He was only 9 months old. They are extremely loyal dogs. They truly love their owners. So, I may not be an expert but I may be able to help with questions.
