It is so sad to see him hopping from time to time. Marni (his vet) is worried that he may need an operation ... and it's something she isn't willing to do.
So we have him on some more pills, and pray that this will be the answer.
He's meant to be being lazy ... but this is a doggy we are talking about. I should ask birds not to fly over, so he doesn't have to chase them!
