Is it normal my puppy is purposely peeing and pooing in the house
I have a 10 week old puppy I got him 2 weeks ago however he is purposely pooing and peeing inside the house. I take him out to go to the toilet and he might do a pee but then he'll hold the rest in when we go back inside to pee and poo. Just now I've walked him all around my backyard for 25 whole minutes and he didn't poo, so I brought him back in and the minute I turn my back he's done three huge shits in the hallway. So far I've just been ignoring it when he does it inside and praising him when he pees or poos outside, but it's not working. Now when I catch him doing it inside I grab him and chain him up outside. Why is he doing this and why is he too fucking dumb to understand he can't go pissing and shitting in the house despite praising him when he does it outside and not inside? Is my dog retarded?
