I try not to laugh - I really do as I tell them all the same thing: congrats, you have a healthy puppy. Too many people dont really understand what comes with getting a puppy. Most just see that cute little puppy face and start daydreaming about cuddling on the couch as the pup rests motionless in their arms. Then they get the little guy home and reality sets in big time.
Puppies are a lot of work and a big responsibility. They dont come from the dealer fully loaded and ready to go. They enter your home as a dog - a dog that has no idea how to live in a very human world with a bunch of furless bipeds. Its up to us to teach our puppies exactly how to behave and get along with us.
Puppies are going to do things like a dog, no matter what. Its our job to show them how to be a dog in the human environment. The good news is that puppies are more than happy to do things our way if we take the time to teach them. And it does take time. Theres no shortcut through the puppy period. You cant get a well adjusted adult dog without the mouthing, whining and occasional accident. That comes standard with every puppy. I feel the puppy months are a rite of passage that every dog owner has to go through. If you survive, you can handle anything your dog will do in the future.
The first few months of a dogs life are the most important and will be the most time consuming for you. I recommend stocking up on a lot of patience when you bring that puppy home. You have to expect them to be puppies. Dont begrudge them for it, accept it and help them to learn. Every bad thing your puppy does is an opportunity to teach him the right thing to do. The worse he behaves, the more chances you have to set him on the right path.
The first day of my puppy kindergarten class is always the same. Everyone comes in with the same sleep deprived bags under their eyes, the same scratches on their hands and the same question on their minds: is there something wrong with my puppy? Once they look around and see that same look on the faces around them, and the same fresh blood on their fellow students hands, they are somewhat comforted, at least temporarily.
Puppies are a lot of work but they are also pure joy. Unfortunately you cant have one without the other (although Ive seen some really extraordinarily good pups). Once a day, youll want to throw you new puppy out the window (sometimes more), however, the smiles that your new dog will regularly deliver to you is well worth the trouble.
So, no, theres nothing wrong with your new puppy. Hes actually a quite normal, healthy pup that will grow into a great adult dog if you just take the time to teach him how to live in your world. Be patient and enjoy every day with them.
