Hi Tina- Most orthopedic surgeons will suggest to do ACL surgical repair on a dog over 40 pounds, and allow the knee to heal on it's own in dogs under that weight range. Since a 4 month old Berner pup is in a grey area as far as weight...I imagine he is about 40 pounds or so already...it would need to be determined by a veterinary orthopedic surgeon if surgery is indeed necessary.
For instance, if a beagle tears their ACL, many vets will suggest rest and anti-inflammatory medication for a few weeks. However, if it is a 'fat' beagle, surgery may be a better option. If the dog is a large breed adult, there is typically no question that surgery is needed. Basically, that is a tough decision to make for a young Berner pup. He is going to have arthritis regardless of surgical intervention or not. I suppose I would follow the advice of a reputable orthopedic surgeon in this particular situation. If she/he suggests surgery, I suppose I would opt for that... and if they do not suggest surgery, I suppose I would follow that advice. Perhaps ask for several opinions from different ortho specialists? Can't hurt to have varied opinions for such a young dog. Let us know what happens- Jennie Hoffnagle Glenmoore, PA
