Have a 4year old border collie who started limping about 3 months ago on front left leg. Had her at vet who prescribed rest and build up walks. As soon as I let her off the lead she was back limping again so today she had X-rays and they said her elbows in both front legs are like old dog elbows and she has been referred to a specialist. Gutted. Any practical advice? Also got to limit her exercise until referral. Feeling guilty as didn't realise she was in pain
