I can understand people litter training their small breed pups when they live in an apt,but if you live in a house,why train that way?There is actuallt no reason to...I have a friend with 2 Bichons and a Bichon/Shih Tzu,and they were never trained in a litter box.
Question,what do you mean he is on a leash inside and has limited freedom?
Ditto on what Luba said...........
Also,they don't have tantrums.....
