So about a month or so I got a GSD puppy. He's pure bred. However my problem with him is, he is really excited every time he goes to be fed, won't sit down and wait for me to put the food down, he basically takes it out of my hands and the other thing is when he is on a leash, he grabs the leash and basically walks himself. Can anyone give me any tips on how to fix these few things. Thanks in advance! It's driving me crazy.
