For the past 3 years, Palmer has been house trained. He is on a bathroom routine and his only accidents were when we first brought him home. It wasn't until a few days ago that I knew something was wrong... Palmer had 3 accidents (of the number 2 kind) within one week. I wrote off the first accident as an off-day... the second accident I thought was an indication of dominance... but when the poor guy couldn't even hold it in overnight, I brought him into the vet right away. When we were in the waiting room at the vet, we saw a Great Dane!
