Scooter...is my families 5 year old West Highland Terrier. Started limping a few days ago and finally got to where he was was turning his hip just to walk. Took him to the vet and he has a torn ACC(same as a ACL in a human) but they cant sow it up like on a human. They have to use a device that holds it together in a figure 8 to get it to heal. Has anyone ever had something like this happen to their athletic dog? Just curious if anyone else has had a similar experience. $1000 fix but he is worth it. Loves to ride the 4 wheeler and tractor and is a beast against a possum.
