The vet said that Dave seems to be getting stronger in his knee muscles. This is the third time that Dave has been to rehab and he's progressing really well, he now uses his back legs a lot in the water. The main problem is that he gets cold quite fast and shivers like mad. That's why he had to have a custom hat made, as shown in the previous post.
So thanks to the power of snausages Dave is on the road to recovery.
