I am so sorry to head about Travis... HD is just a huge bummer, and it's so common in his wonderful breed. =,( I really hope that he can live comfortably, whatever it takes. And I hope you figure out what's going on with his thyroid. Has he been losing weight?

The pictures are awesome, as always. It's nice to see that he is still playful and active. I'm sure it helps that he's such a muscular boy! Good luck with the CGC classes, I'm sure they will be a cinch. : )
