Training and potty training an adult dog
So i got this 2 years old gsd rottweiler cross-breed dog that has never been trained at all. He's very stubborn. I'd love to train him to become a litle more obedient.Plus, he's get this problem of pooping and peeing anywhere and even sitting and passing on his poop. I must say that he's nearly always tied on concrete but got a little soil near.So, i'd like to potty train him strictly so he'd become cleaner.I hope i've been clear enough cuz i'm not very fluent in english :/
PS: i'm a first time dog owner.
