Darrell,
I think if outside works for you, then go for it! I potty chloe outside, and I personally think that they train much faster when they're trained to go outside. I know many say that yorkies are hard to train, but Chloe was housebroken by 5 months, and we potty her outside on command. I thought she was rather easy to train, but of course each dog is different.
good luck! |
