I have a 6 mo old Cocker that just started pooping in her crate. She has been crated since I got her at 8 weeks old & has done great until this past weekend. I have been leaving her outside on the weekends since she likes being outside. I bring her in at night to sleep in her crate. This has been the only change to her routine. Could this be the reason for pooping in her crate? Thanks.
