When it comes to puppies, the first thing that comes to mind is how cute, cuddly, sweet, and playful they can be. After all, who can resist a puppy? (I have two, so, obviously, I cannot). As your pet starts to grow and get older, though, you quickly begin to realize that you might have a problem. As adorable, cuddly, and playful as your puppy is, they’ve started showing signs of aggressive behavior as well. This can be worrying. After all, if your puppy is aggressive now, there’s no guarantee that they will naturally grow out of this aggression – it could get worse as they get older.
