Looking for any advice for dealing with a partial or completely torn CCL in large breed dogs (specific treatments/supplements, great affordable vet references for TPLO surgery etc). We are just starting our research, he is a neutered male Rottweiler/Catahoula cross. He is almost 4 years of age and has been on a well balanced raw diet for about 5 months now. If you deem this unacceptable for your page I apologize, just looking to gather some information from dog savvy individuals as well as professionals.
