I am happy to report that Jasper's first bath went pretty well. I got in with him and he was really unsure at first but I held on to him and talked to him gently, and of course gave him lots of treats! He wasn't too fond of the water, and started whimpering about halfway through. Once we were out, though, he loved getting dried off and seemed really happy to be clean. I'm not sure he's going to be one of those rare dogs that love baths, but he tolerated it really well! Unfortunately, I couldn't find my camera to take cute pictures, but I will be armed and ready next time! Thanks for all the help and advice!
