Jumping on people is a common greeting of many dogs, but, while perfectly normal for a dog, most humans would prefer their pet keep all four paws on the floor. And especially if those paws belong to a dog or puppy that is going to grow to over 100 pounds.
It is a common question – when should you begin training your new dog or puppy? The answer – as soon as you bring him/her home. Really, from the time that your new friend enters your life, he is already learning what to do and not to do simply by the feedback he receives from his environment about the behavior.
