I am glad to hear that his UTI is gone. It might be good for dogs to be left for a few days and then come and pick them up, just like it is good for kids. It teaches young kids that mom, dad or whomever has not 'dumped" you, they will come back. I wonder if dogs would see that connection? Good news that he howled, I have yet to hear Otis, although he does have his own language going on when I vacuum clean.LOL.
