All my rescue dogs, house trained or not, took a little while to figure out where to potty! Potty training takes time with young ones, especially when they are playing hard with the others and need to go. Rocky sometimes forgets, goes on the floor, and continues playing - that is until someone reminds him that WE DO THAT OUTSIDE!
A rescue or new pet takes at least 60-90 days to adjust, and sometimes it takes a lot more time, like in Bailey's case. One can't give up too soon. Once a dog is adjusted to their new home, life is good.
When it rains, watching the Basenjis running in circles, deciding whether they should go quick in the house, pretend they didn't do it, and play innocent - or just brave the weather, do their business outside, and listen to Mom praise them. I'm doing a lot of praising these days - as Georgia has been pounded with rain for weeks!
I have a very good steam cleaner that gets used often! With six dogs, it is the best investment I've ever made.
