LOL! I had to laugh when he noticed you and stopped...too funny Cute video, I'm glad you posted it.

Sorry to hear that he's having a hard time. Have you tried any type of supplement? I had a lot of luck with this...Synovi G3 Soft Chews
They are expensive, but sooo worth it. If you can't afford that, I know Phred has used the Glucosamine/Chondroitin supplements from Wal-Mart (I think around $20 for a big bottle)
