We have 2 female chocolate lab puppies - one is 9 mo and fully trained, the other is 3 mo and learning. The 3 mo old is great when out - she doesn't have accidents in the house, she goes outside, but as soon as she is crated - she poops her crate. She will poop outside before we put her in the crate, and still poop her crate. What could this be from? Our 9 mo old is not crated, runs the house and is great!
