Is it okay for my new dog to share a bed with me?

I've been told that you shouldn't let your dog in the bed with you because they will think they are the boss of you rather than vice versa. I think it depends on the dog. If you have a dominant dog, I probably wouldn't do it. Our dog is sort of a chicken, so we let him sleep with us on the weekends. He loves it, but now thinks it's his bed. I don't mind, whatever I have he can have. He will sleep in his bed without complaining if I want him to do so. If your dog growled at strangers..hmm. Did she back up as she growled or was she lunging forward. Backing up just shows fear, lunging is aggression. Even if she is being aggressive it's best to stop it now, just say NO when she does it. Praise her like crazy when she doesn't do it. She'll get the idea. Food is a great reward for your dog when trying to teach them new things. Be sure to wear hats, sungles, blow whistles, etc. when she is little so she won't be scared when she's an adult. Rubbing her belly and touching her ears, paws etc is a really good idea too. My dog has not become aggressive since sleeping with us, but he does think he's the boss sometimes. He's a Boston Terrier so that's to be expected. Best dogs ever.
