7 month old Puggle, going backwards in house training!!?

At 7-9 motnhs is when they go through their teen months. Like many vets would tell you, it seems like they forgot everything and seems like they are an awful dog but once they get through this rebelious period they will be back to the obedient dog you once knew and loved. They are just like humans in this way, they wont listen and they wont follow the rules and they even do things just to make you mad, you just gotta get through this point and they willl be a good dog again. Ive had many many dogs and they all went through this (the little dogs are evn worse during this time) but dont worry they will be good again. For the chewing i suggest an anti chewing spray. Its 100% natural and 100% safe. It has a really bitter taste that dogs hate but no odor. Its safe to use on anything (except the dog itself) even leather couches, it can be bought at walmart or any pet store. But as far as the behavorial problems right now, there isnt really much you can do about it during their teen time.
