Hey just wondering if you have some insight on this situation: My boyfriends dachshund used to be very well potty trained and he could let her roam his place freely. Then suddenly she started going pee everywhere as if she had never been potty trained and he has to keep her confined to the bathroom usually because that’s where her bed and stuff is and she won’t go potty there. Do you know why she’d suddenly forget her potty training?

Sometimes a UTI can be the cause. I would take her to the vet and have her urine checked before looking at behavioral issues.
