Ideally, our dogs will learn to be well adjusted members of our family and can be comfortable in their home environment, but sometimes it takes some training to get them there.  The Behavior Vets in Castle Rock recommend setting up emergency stations in your house for situations where your dogs may become aggressive with each other or people.  Please remember these are supposed to be used in TRUE EMERGENCY SITUATIONS and should be avoided if at all possible!  If the problem can be managed by walking away from your dog or removing your dog from the targeted individual/stressful situation, do that instead.  You can even try tossing treats at your dog's head to get their attention (this will likely only work in the very early stages of excitement).  Anything you do can hype up your dog more so always proceed with caution!

Glasses of Water Around the House - Place 4 oz. glasses of water around the house.  If your dog starts biting you or a guest, and the individual cannot get away, toss the water in your dog's face, aiming for the nose so that your dog has to gasp for air (and as a result, temporarily stop the aggressive episode).

Spray Shield - can be bought on Amazon.com.  Make sure to follow the instructions and practice (away from your dog) before you ever need it.  

Blankets - To distract your dog you can throw a thick blanket over his head and this will allow enough time to release the bite

House Leash - Keep a long line on your dog in the house (Remember to keep your dog in another room or safe zone (crate) when you have guests over) and have it attached to a body harness or head harness.  The leash should be at least 5 feet in length, with no loop at the end that could get caught on something. This will give you added control.  Test this out before a stressful situation to make sure it doesn't cause the dog to become more fearful.  Only do this when supervised by an adult.  

Crate - Use a crate as a safe space for your dog to retreat to.  This space needs to be just for your dog, and people need to leave the area alone completely.  No one should go inside to play or get your dog. Keep the crate in a quiet area and away from high foot traffic areas.  Call your dog to come to you or offer treats when you want them to come out.  If your dog does not come out (unless the house is burning down), ignore the situation until your dog comes out and interacts on their own terms.  

Your dog will need to be able to lie down comfortably and have space for food and water.
