She has now peed in the house 2 days in a row. Is this common for dogs to fall back in their training a bit? How concerned should I be?
This happened with my 8 month old not too long ago. He peed inside a couple times in the middle of the night. He hadn't peed inside for months before that. He was and is fully potty trained. I took him to the vet and he had a Urinary Tract Infection. He took his course of antibiotics and it hasn't happened again since. So if you sense something is wrong, or not normal, I would take her in, especially if she hasn't had potty training issues in a while.
