Here's my theory...I have trained my dogs in the past to go potty on command. Their command was "Hurry" I am now training my new little Yorkie to use pee pads because the weather has been yucky and cold here in Maine. I am using the command with him when he goes potty so I am hoping that when I decide to start training him to go outside also when the weather gets nice, that he will go outside because he knows the command "Hurry". Hopefully it will work!
