Basset Hound is Resource Guarding

Question
Thank You For Your Help, Dr. Conner,
I have four dogs, A Malamute, two Toy Poodles and a Basset Hound. I needed to move my mother in with me to take care of her. Of course, her Basset, Mollie came with. Mollie had been an outside dog and an only dog and not very socialized. She's been with me four months. I have house trained her and she is generally very well behaved. There have been, however, several incidents when she has jumped the other dogs. Twice when the Malamute has approached my mom. And also over smells in the backyard with both Poodles. The events occur at about 2 week intervals. I have dominant rolled her and she's very sorry. She has never bared teeth and there has never been any actual fights. The last time, however, my husband yelled at her to stop and she would not. He physically had to remove her from the Poodle, who was pretty upset. Still, not even saliva on him. We have decided that she should not be left alone with the Poodles anymore. Besides these isolated incidents, all four get along well and seem to like each other. They play everyday at the park and feeding time goes smoothly. We have finally worked out sleeping arrangements that work and Mollie does not guard furniture. Should I just accept that Mollie should be watched when she's with the Poodles? What else can I do to get her to stop this behavior?

Answer
STOP "dominance" rolling this dog.  Dogs do not go belly up by force: it is a VOLUNTARY display of submission.  All you do when you enforce what is (in the dog culture) a voluntary display is to confuse the dog, it does not teach her a thing.

No dog should ever live in social isolation by being confined outdoors.  This dog has had an enormous adjustment to her new environment; not socialized in any way, not trained in any way, she has NO way of knowing how to please (offer behavior that can be rewarded) and is, essentially, attempting to obtain a place AMONG the actual dog pack (a member of which you, and other humans, are not.) Considering her total lack of socialization to other dogs, she's doing very well. This is a scent hound: such dogs can be extremely driven (prey drive) when tracking scent and her choice of behavior toward the other dogs is not a function of cognition, but rather the result of no appropriate interaction with other dogs coupled with her strong, genetically driven urge to follow scent.  Leaving her alone with any of your other dogs is not a good idea, but supervised interaction is fine.  Put a house tab on her (leash with handle cut off) so you can use that to remove her from a situation where she is displaying unwanted behaviors toward the other dogs.  Your husband was unable to redirect her, or stop her, by yelling because she is "locked" into her response to the Poodles due to their interference with her when following scent.  You've done a wonderful job of house training (it's quite difficult to house train an adult dog that has no habituation to indoor life).  Your next step is to TEACH her some behaviors she can offer you for reward.  I suggest you do this by going to DogStarDaily.com.  This is Dr. Ian Dunbar's site and you will get a full introduction to his method of positive reinforcement training by watching the following video:

Look around on this site for videos and articles that discuss training the adult dog, especially one with some problem behaviors.  An especially good technique to interrupt and redirect unwanted behavior is to teach the dog to "sit" (use a unique word) on cue (command) after stopping the problem behavior, i.e., dog is growling as Malamute approaches mom, pick up house tab, walk in a circle, then ask for "sit" for large reward.  See this video as a primer:

Teach this dog in various rooms of the home and then outside in the yard (other dogs absent in all cases), then "practice" randomly (once she clearly understands and complies) with other dogs present.  Use the house tab to remove her from situations you don't like, redirect immediately, then ask for "sit" and reward it.
