I dropped my 7 month old Boston (Roger) and his companion Daisy off at my friends house for the weekend while I went away. Roger's been to this house before a few months ago with no troubles, this time, he constantly peed and pooped in Jen's home, even after she let him out. Roger is house broken, at least at my home, with maybe 1 accident, usually my fault a week.
Any ideas? He's been good since he got back, I'd hate to lose a dog sitter.
