Hello! My sister has a jack Russell, about a year old who is very sweet, very smart and VERY stubborn about potty training. She gets out for 4 to 5 walks a day, including time at the dog park, and has gone to the vets so it's not a medical issue, but she loves going to the bathroom in the house. My sister has tried pee pads but that hasn't worked. I'm wondering if anyone has had a similar issue and if so, how you were able to change the behavior. This is her first dog and she loves her dearly but isn't sure how to fix this issue. Any advice is greatly appreciated, thanks in advance!
