We reciently got two 8month old australian shepard/lab mix puppies. One of them just seems to uncontrolable pee on himself. the dog and my DH were sitting on the couch today and he just let go, not even realizing what he was doing. he does it in his sleep and pee's A LOT!! I have had many puppies b4 and none of them have done this. they would at least squwat or hike a leg. Is this normal for puppies??? I am getting so tired of cleaning up pee!!
