Max did this when he was a pup, all the way until he was four or five months old, and once in a while, he will have an accident in the crate, maybe like once every few months now. He is gradually getting better at it and finally learning that his crate isnt a potty...we had a hard time
potty training him too...Max has been a difficult one with the poop and pee!! hahaa...Like Jade said, about the crate possibly being too big, was what I was going to ask...but if you said he only has room to turn around and lay down, than that should be small enough for him not to want to go...When Max was still going in his crate, we got a seperator thing to put in the middle and gave him the smallest amount of room possibly comfortable. I felt so mean for sticking him in the smallest spot ever, but in about a weeks time he finally stopped pooping in his crate, then I just got some puppy pads and put them in his crate for the pee accidents, everytime I thought he finally stopped having accidents, I would remove the seperator, and he would start peeing and pooping again, so I had to keep it in there until he finally grew into the crate. I felt like such a bad mom, but Im sure its not healthy to let him lay in it if I could stop it, ya know...he now finally doesnt ever poop in his crate and he has a crate that could fit two boxers in it, he is a year old now...he has pee accidents once in a great while when we have to leave him in there for a longer amount of time. Hopefully you get it figured out, I know how horrible it is to come home to poop everywhere...its no fun!
