Think about it you come home the place is destoryed are you happy to see the dog I dont think so. but crate trained you come home the house is in order you get the leash and go for a walk you are happy and the dog is happy and no 2 to 3 hours cleaning up the mess or spending hard earned money to replace the damage. most of all the dog is safe in a crate. and can not do something that could hurt hi
