I have a 7 year old lab, border collie, pit bull cross and we just recently spent over $4000 on replacing his ACL. As a result we had to change his food and start giving him glucosamine powder. Now whenever we take him for a walk he gets a nose bleed, but it doesn't bleed any other time. He does get excited when we take him as the last couple of months he has be home bound due to surgery, not to mention he also put on a few pounds as well...but he is not overweight. We really do not have anymore money to spend as we can barely make ends meet ourselves. I love my dog but I'm feeling very torn on what I can do. If anyone has any suggestions that would be greatly appreciated!!
