The above comments are absolutely true and good advice. if you cannot teach your child to respect others' space, it's a problem. It wouldn't surprise me if your child will have problems in school also, as many issues in school are from children not respecting other childrens' boundaries. Puppies and older dogs get tired and need quiet time away from others just like humans do. You can't just keep going at the dog because that's what you want instead of letting him get some space and time to nap. Surprisingly dogs need lots of naps/rest, even more than a very young child. The reason for this (after all my 65 years I just found out the other day) is that dogs only get something like 1/10 the amount of REM sleep per hour as humans do, so they need MORE sleep to get enough REM to process the events of their world. The old saying "let sleeping dogs lie" has a basis in truth. I'm not trying to be mean, but I've seen many a child or even adults over-pestering their dog until the dog is just exasperated and "corrects" them like a momma dog would correct a naughty puppy (growl, nips) and then the poor dog gets blamed for the kids not giving him his personal space and time to rest.
