Hey gang! I've had my wonderful Preston for over three years now and my vet thinks he must be at least 10 years old. He seems to suffer from degenerative myelopathy, among other old-man issues. I was wondering if anybody has any senior pet supplements that they recommend for their older babies. I'm trying to find something that might help him keep his mind a bit longer, if possible. I love my old man :) Thanks for any suggestions!
