The past 3 times we have left the house, I've come home to find she's peed in her crate. She's four years old and we never had any trouble training her as a puppy. I haven't found that she's peed in the house otherwise (at least not that I know of... ) Her going out schedule hasn't changed, diet hasn't changed, so what's going on? Is she all of a sudden really mad at being left at home after 4 years of the same routine? I'm a stay at home mom, so she's never in her crate for long extended times.
