Liz, he is doing very well with housetraining. Or maybe I am doing well with being Tucker trained. But he is able to not have accidents over night now and is barking when he needs to go out when he is in his crate. When he is out of the crate, with all the other dogs and kids around, you just kind of have to keep an eye out and know that soon after eating or playing he needs to go out again. He is still going to work with me and is doing very well there. (I almost hate to say that out loud) Since it is just he and I most of the time, he is contained in my office and it is pretty easy to know when he needs to take a trip out.
And Phred, I thought Pippi was tiny too until we got Tucker. Poor Tucker he probably won't ever be allowed down to run and play at the dog park with his over-protective mother!
