Hi, I am new to this forum. My "baby" Chloe, a Berner (who looks like a Swissie b/c she has a rare genetic abnormality - she is a Berner with AKC papers but she has short hair), seems to be slowing down. She was 5 this June. She was always very active and friendly (if not a little cautious with strangers). Between January and May of 2007, my poor baby had four surgeries to deal with two ruptured ACLs - we opted for the TPLO surgery. She now has arthritis in both knees and bilateral hip displasia. Her companion died in November and we got a lab puppy soon after. They are great pals, and Chloe tries to keep up. But we have noticed that she's hurting a lot (our orthopedist told us to expect this and we give her medicine in cycles). She also sometimes growls at strangers, even if we invite them into the house (she is WELL trained with several rounds of competent professional training and constant maintainence). I am really sad and wondering if this is normal.
