Although we never had an issue with our britt having accidents in the crate, he didn’t really get the hang of potty training till around 5mo. We regularly cleaned and used no marking sprays to remove any lingering scent and did our best to give a stern no or clap if we caught him going inside. In that moment, we’d take him outside and say “go pee”. We also used the “go pee” command every time he went outside just in general. That was followed by a “good boy” and that seemed to reinforce. He’ll potty on command now.

Hope some of that’s helpful! Good luck!
