Everything about taking them outside regularly and praising them to perform is good.
One of mine is a escue who used to be beaten when he messed inside. He was left from 8 in the morning until quite late in the evening tied in the kitchen.
He has apoplexy when he gets loose and cannot make it to the door.
Does not happen often but when it does it is just cleaned up with a bit of Bio powder or soda in water and no fuss made. Doesnt half meky you feel queasy first thing in a morning though.
We trained the other dog, who was a puppy when we got her and she learned very quickly. She is a bright dog though and wants to please.
Frequesnt outside visits with wee as a command, always after waking and food. She now goes to the door and asks with a whine.
You will get there with yours I am sure.
What an idiot to rub a dogs nose in the mess. Obviously time will have passed. The only way to control behaviours in dogs are at the time they happen.
Some people have no idea at all. Makes me angry
