Say you step out for a minute and then when you come back into the house you find a puddle right on your newly installed wooden floor. Standing near the puddle is your puppy wagging her tail and happy that you are home. You on the other hand are tempted to throw a tantrum because how dare she ruin your new floor. This is just one of the scenarios in which you need to watch your reaction. Just because you are mad doesn’t mean you should shout at the puppy. Instead clean the pee and work harder on training her to make her messes outside. She is just doing a natural act of emptying her body and doesn’t know why you are so mad. Shouting at her only makes her fear you, ultimately ruining your relationship.
Even worse than shouting is spanking. Never at any one point hit your new puppy no matter how angry at her you might be. Like someone once said hitting is for punching bags, not puppies. Spanking a puppy makes her lose her trust in you. It is simply bullying and should be avoided at all costs. Instead of hitting the puppy it is better if you learn ways to train her to do the right thing using positive reinforcement.
Other mistakes you should avoid relate to perspective. For example if you want your dog to associate grooming tools with happy feelings, get her used to those tools early on. Brush her coat often and clip his nails once in a while. This way, she won’t be too much of a bother once you decide to take her to a professional groomer, because he is already used to being groomed. In addition, take her in your car to happy destinations such as the park or to the pet store to get his treats. If she only boards the car when she is going to the vet then she will associate car rides with pain and she will therefore give you problems or refuse to board when you need her to.
