Agressive dog behavior

Question
My dog is half great dane, half coonhound. She is around 10 months old. She has very bad aggression towards food. And if my other dog walks into the room, she growls. If me or another family member walk up to her to pet her or give her a command she growls. And it just get worse. I dont understand why she is doing this. I am due to have a baby in December, and i cant get rid of the dog, How do i make her stop? I am the only one in this house that likes her, but she despises me the most. Please help me. I love my dog so much.

Answer
You have a serious problem.  This is a large dog, one that could do incredible damage to a small child.  Not only is she is a "resource guarder", but she does not respect you or your family members' authority.  Unfortunately, while you can train the dog not to guard her stuff (food, toys, special chew items, etc.) against you, the likelihood that she will respect a small child in the same way is pretty small.  If you keep this dog, you can never have her in the same room with food and kids!  If you would like to try to train her, then you can buy a copy of Jean Donaldson's book "Mine! A Guide to Resource Guarding in Dogs".  I would also suggest that you enroll her in a positive training class, and you have no time to waste if you are already pregnant.  She needs to learn that she is not in charge of your household, but you must do that in a non-aggressive way, as this dog may decide to use her teeth in response to any aggression on your part.
I know that I make this sound serious, but, when it comes to the welfare of very small children, it is.  Most dogs are fine with infants (but no dog, even a nice mushball of a dog, should ever be left alone with children who are under age 10 - the way you protect your kids is to protect your dog).  The problems often arise when the child is toddling, and falls against the dog, or puts a hand out, or grabs an ear, or sticks a fist in the dog's food bowl.  You can just imagine the scenarios that could lead to a bite from such a dog.  So, in my opinion, act now before your dog has a bite history!  If you have any trouble, find help from a behaviorist near you.  (IAABC web page)
