Shiba inu owners, advice?

If he doesnt go outside take him in and crate him keep doing this hell get the message that he is not going to be part of the pack if he doesnt obey the rules be firm. Try taking him on a nice long walk sometimes they need to get moving to get it going! Make sure you give him lots of praise when he does go. If he goes in the crate(most wont) then you have to walk him eventually its gotta come out try different areas. My pup will only poop in something tall like overgrown grass or ivy weird huh? Good Luck
