well chatty me will comment .... Every Bully is different Cooper likes to snuggle and cuddle and gracie would rather be left alone and sleep by herself in her own little ball or in her crate. Cooper loves to cuddle but radomly he will go in his kennel and sleep. So yes this is normal behavior for bullies! Also the peeing and pooing can be from maybe the kennel being too big???? Are you getting up and letting him out to go potty or is he whining to get out to go? Cooper had his accident in the kennel more pee than but when the accident came UGH It would be all over. I don't know why they feel the need to roll in it and get it all over the crate. Cooper would have random accidents like I said until he was around 4 or 5 months I think. He didn't have many but they would happen here and there. Sometimes them being my fault and not hearing him whine to get out. Coop is now almost 8 months and I can trust him enough to roam the house. He is rarely crated and hasn't been for 3 months now. He sleeps with us in our bed too. If I am leaving for a long time I will crate him cuz who knows what the little booger would find and get into! Gracie also is a free roamer. My mom just started letting her run the house about a month ago. And she will leave her for long amount of time!
So Yes your Pup is normal!! Just a normal stubborn do what he wants bully!
