Hi, I have an 11 year old retired rescue greyhound. Had her since 3 years old. Her back right leg is now lame. shes in pain and cant put any weight on it. Been to our usual vets, she has had 2 lots of x-rays and bone samples and blood tests taken since end of February. Its Getting worse and the vet doesnt seem to know what to do next. Could it be a gracilis muscle injury? Our vet is a general veterinary clinic. Any advice, good vets, direction and information etc would be great. Thanks Don.
