I've had my 6 month maltipoo for about 2 months now. She is normally home alone from 8am-1pm but usually no more than that. She is crated when left home alone and she enjoys her crate when people are home. Usually when I come home she has peed in her crate. She doesnt bark or try to escape the crate, only pees in it. I believe she is well potty trained and she hasnt peed inside the house when supervised. I know this is a type of separation anxiety but how do I fix this? I do everything you're supposed to when leaving a dog alone like leaving the TV on for noise and walking her beforehand.
