Thanks for all the responses. I did get ahold of his breeder, and there have been no reported problems. His vet is amazing, that is why I am waiting until Tuesday... he has been working with basset hounds for over 20 years, owns and breeds them himself and knows them in and out, so I trust his advice and diagnosis. He personally called me from his vacation and told me as long as Noba is continuing to eat / drink, then he should be able to wait. Noba has been trying to do things, be energetic... he tries to play, but only for short periods of time. Instead of walking, he prefers to run because it puts less pressure on his leg quicker. I will update you all tomorrow after his appointment. Thanks again...
