A few weeks ago we noticed Idjit limping on his left front leg. Went to the vet and he was not cooperative at all, even aggressive, so they couldn't see him walk. He was sedated so that they could examine the leg and paw for any injuries or claw problems. No obvious issues. They trimmed his claws and he got to come home, with the offer to bring him back for X-rays. He improved, but now and again I would see him limp after he got up from a long nap, like he was in one position too long and was stiff..maybe some arthritis? This morning he is limping on the right side, so I am thinking of using a supplement to help his joints and see if that eliminates or reduces the limping. I have looked at 1-TDC which also helps with periodontal health, so would be beneficial that way also, but I'm wondering just how much it would help possible arthritic joint issues. His appetite is great, coat, skin and eyes are healthy looking. Just the limping. If anyone has input or has dealt with issues like this, please chime in. I'm more concerned than ever.
