One potty spot in yard, when out alone
I have an 8 month old male puppy. I started training him to "go to his spot" on the treelawn out front, but we've just fenced in the backyard for him. We take him out multiple times a day on his leash to his "new spot" in the back. He usually goes pee immediately, but rarely poops there. When he does, he gets a treat and lots of praise. I've noticed he tends to go poop a few minutes into a walk (but I don't like carrying a poo-bag around the neighborhood), so I've started walking him on his leash around the backyard (no playing) until he signals "poop time" then I take him directly to his spot, where he finally poops, and then sometimes we go for a walk. So when I'm with him, he's really good about going to his "spot". I'm concerned about when I'm not with him; when I let him play outside by himself for an hour or two. He goes poop wherever he darn well pleases when he's alone! How do I get him to know he needs to go to his designated "spot" no matter if I'm with him or not?
