hello i need help
Hello, we have Greta and Crash. Lately, anytime we take Greta outside and leave Crash inside, whether he is crated or not, but especially if he's crated, Crash goes bonkers. It's difficult to correct him since he's in his crate. He does his high pitch barks and yelps until we get back inside. Any tips or drills that would help with this? Thanks in advance.
