How do you get a 4mo puppy to understand going outside to potty is not time to play? I bring him back in after 20 mins and put him in the crate for about another 20 mins and then back outside again. I usually take him to one area of the yard and and let him walk as far as the leash lets him and he will go around in circles picking up whatever he can find in the yard having a blast. I repeat go potty but it's like he doesn't even hear me. He will go both pee/poop first thing in the morning on leash outside but no matter how many hours we do the 20 in/ 20 out he just will not go outside. All he wants to do is chase blowing leaves or eat the dormant grass. We let him know how happy we are when he goes outside in the morning with treats and happy voices and play a few minutes before coming in, but can't figure out why he won't go any other time outside. He was paper trained by the breeder (up north where it was too cold for the puppies to be outside). I've gotten to the point that by late evening after he has two meals inside him (lunch & dinner) and still doesn't go outside, that I will put down paper just so he will go and not hold it inside any longer. Anyone have any suggestions?
