Well… blakeandsam is a med student right now, so… I'm sure that will come in time
@Chaney…. I'd really recommend the Potty Bell
trick, especially if your dog is just waiting around and counting on you to notice rather than crying or barking. From experience, it really works and for some it's the final thing that solves those extra house-training issues.
Until such point as he is very on cue about ringing and going though, I would keep eagle eyes on him. Some puppies just think that life is too fascinating for potty-breaks and don't realize that they have to go until their back teeth are floating!
The grooming… going to a groomer can be worth it just so you can see their routine, what the cut looks like and whatnot so that you can try it yourself. To get the dog to become used to grooming you basically just have to counter-condition: go slowly, reward lots and be gentle!
You may find that reserving something really special like pig snout or a bully-stick for grooming time makes the job easier because not only is the dog continuously rewarding himself while you're brushing him, he's staying put because he's so busy with his snack!
So yes, edible chews are really handy wherever you can involve them (obviously the tub is not going to work).
For bathtime… you may find that he takes a bit better to being rinsed or splashed with water than simply plopping into the tub whole-hog. Those detachable shower/sink heads are great; they're actually probably what your groomer uses. There's also a lot to be gained from starting with the dog's legs and feet rather than starting by dousing them from the head or the back. As you might guess if your dog likes jumping in puddles, the legs are a lot less sensitive to the change in temperature than other parts of the body!
