is it normal for dogs to go through a rebelous stage?

My dog is a little over two years old now and he has his days where he could care less of what you say to him that hes not going to listen. He is getting better most days but he still has his days.

There can be many reasons a dog can forget what they learned. It could be strees: if something has changed in your life they can sense it: it can be seasonal, the winter blues, dogs can experience depression just like people,:could be health related, have a vet check-up to rule out anything: could behavioral, a dominate dog, you might have to re-affirm their training. For pooping and peeing in the house I would start putting him outside every 1/2 hour to do his businees and give praise when he does outside it just reaffirms that he's to go outside to piddle.For getting into things that he's not susspose to seems like he might be bored, so take some time to play with him. A Good dog is a tired one.When it comes to stealing your daughters food, he's trying to show his dominace over your daughter, his place in the ranking,in the pack order, he thinks he should rank before your daughter.These problems can be fixed with patience and reaffirming his place in the pack.

my dog was really well behaved. but since hes gotten older, he doesn't listen at all! he just loves to push our buttons. i tell him to leave my room, he just jumps on the bed. i tell him to move off the bed he moves on the other side of the bed!! he started peeing and pooping on the floor too! hes starting to get physical problems, and cant hold his bowel movements as well as he used to is your dog old?? there might be more issues other then her being "rebellious"

If it is a young puppy then usally yes they do. Then as the get older they get beter. Usally after 2yrs old.
