I think you should do it. Aldo does need all the help he can get and not for you to give up on him. You should also ask her what you need to do for training for you and the girls because you are right, if you don't change anything at home, he will go right back to his old ways. So it's not just the dogs that need training but the whole family does as well. Aldo and Katara need rehabilitation and you and the family need training!!! There I just channeled my inner Cesar!
