Nearly a year now we've had the new mutts. On the potty training thing, i uncovered & redone our previous dog's dog door a month after getting them. Helped tremendously. Got them narrowed in to concrete area of backyard only for now & trained them both to go to a 4 x 6' section of fake grass. The girl mainly still uses it, but the boy gradually more so just goes where he wants outside, just keep a scoop & hose & nozzle ready to go at all times. Hope to next year expand their backyard area.
Now, on the in the house training, didn't know 1 little thing till the day we were picking up dogs to bring them home. The 6 puppies lived on a farm with 3 other dogs. The daughter that owned the puppies never let them outside for fear of getting parvo or something before getting vaccinated. So she trained them on pee pads & get this--------- RUGS. What does most every house have that you don't want a dog to pee on ????? So we have them limited to front of house only & can't have rugs, just keep a small towel near dog door At the moment it's been weeks since I know of finding pee in the house, but it will just never be a 100% thing with them, EVER. Rainy days are still challenging & the wife keeps brown couch covers on the couches, washing weekly outside of any accidents. White or blue towels or covers are a target for them. Hope to afford leather furniture sometime here.
I did get one Winix air purifier with carbon filter, does help some for the mini hound dog smell.
