Hello! My large 5 yr old female pit has been on Glucosamine for a few weeks now due to us noticing some limping on her back left leg. It seemed to have work really quickly since she hardly was limping within a week and could go up our backs steps without hesitating as before. BUT...last night she was barking alot & we think she was standing/leaning against our fence while she barked..so today she couldn't get on all fours and I used a towel sling to help her go down the steps. She is just laying around now (& still barking @ the world..ha!) and now my husband tried putting a sling around her and for the first time ever she growled at him when he got near her back leg with the towel..I know she's protecting it but we really think its best to bring her inside our home and away from the cold. Help! Any suggestions!!??!! How long will something like this take for her to get better? I think she got confident & thought she could stand on her hind legs since her leg had improved sooo much and now she is hurting our other pit tried to get near her & she growled at him too
