How to stop my 2-year-old dog from attacking family and housemates?

Desensitization and counterconditioning Desensitization is the process of taking a fearful stimulus and slowly exposing your dog to it. You have to start slowly and gradually increase the amount of stimulus that your dog is exposed to, until she is no longer responding negatively to the stimulus. Counterconditioning should be used in conjunction with desensitization. This is the process of pairing the fearful stimulus with a reward, such as praise or a treat. Your dog thus begins to associate the previously feared stimulus with positive emotions. An Example of Desensitization and Counterconditioning: Dog Afraid of Men In a spacious, neutral environment, like a park or large fenced yard, start with a man at a distance from your leashed dog where she does not cower, growl, try to run away or otherwise appear fearful. Make sure you have a good amount of high value treats to work with, which may be hot dog pieces, cheese, etc. Small treats given fairly constantly with proper behavior are a great tool. Adjustments to distance from the stimulus should be gradual and paired with constant treating while the proper behavior (i.e. lack of fearful behavior as described above) is maintained. Your dog may reach a point where she feels threatened and may display signs of fear toward the man, possibly even aggression. If this occurs, expand the distance and repeat the process. This technique can be adjusted and applied to most situations that cause your dog to be fearful. Conclusion Keep in mind that this is a process and will take some time. Have reasonable expectations of your dog and what is acceptable behavior within your family unit. Each fear will likely have to be addressed separately and may never be abolished completely. And as with any training exercise, it should be fun and a great way for you and your dog to bond! Adding obedience training or agility classes may make the process smoother and ultimately more enjoyable for everyone involved. For further information and help, especially with working with specific triggers, please contact your veterinarian.

I hate to hear this is happening. I;m sure it's not only scary but stressful as well. Canine aggression is a complex behavior as it can stem from dominance, possessiveness, fear, anxiety, resource guarding or a combination. Most people are not familiar with reading canine body language and training. Because of this, I recommend to work with a professional trainer. Researching on your own will also be helpful. Familiarizing yourself with canine body language and dog training can help you to recognize what your pet is trying to say. You can find many books written on the topic and there is a trainer named Victoria Stilwell who I think is particularly helpful. Also, dogs who are spayed and neutered are less likely to fight though this is not always the case. I recommend to discuss having both dogs altered with their veterinarian. Best of luck.

This is a hard question to answer without really knowing what is going on. If Max is becoming aggressive, growling, snarling, attempting to bite, etc, then this is a very complex and worrisome issue that should be worked with by a professional in your area. A trainer coming by in person can help observe what is going on, and provide more tailored training plans to address the issue. If Max seems nervous when you approach, you can work on getting him more comfortable with you by tossing a favorite treat to him every time you approach. Over time, he'll start to associate you with with something positive (the treat) instead of something negative. If he does growl or become agitated, moving away and giving him some time to relax before trying again is best to avoid escalation of any behaviors. If he is acting aggressively toward other dogs, separating him if things get too rough or a fight breaks out, and then reintroducing both dogs again slowly can help. Removing items of contention such as toys, bedding, bones, etc can also help reduce the possibility of a fight over these items.

I'm sorry to hear that your dog is having this problem! Behavior issues like this are quite complex, and often very difficult to handle successfully on your own if you don't have any training experience. And particularly with an aggression problem, it may not be safe to attempt to work on this without professional assistance. If at all possible, I would strongly recommend making an appointment with a veterinary behaviorist who can evaluate your dog in person and help you put together a detailed plan to work on the problem. Although the initial visit may be somewhat expensive, in many cases owners are able to stay in contact with the behaviorist via phone or email about how things are going without the need for repeated in-person sessions - which cuts down tremendously on the long-term cost vs. working with a trainer every week. The behaviorist may also recommend medication or other adjunct treatment options that could be helpful in addition to the training plan. You can search for a board-certified veterinary behaviorist here: www.dacvb.org If your dog is mainly aggressive to other dogs when she sees them on-leash (the most common form of this problem, in my experience), I would also suggest the short book "Feisty Fido" by PhD behaviorist Patricia McConnell - it has very sound, useful advice for dealing with this issue that may help to get you started.

I strongly recommend you consult with a professional, in-home dog trainer. You need a trainer to come to your house and see the behavior and the interaction of all the family members with the puppy. This is your best bet. Aggression problems need special care and it is not recommended that you try to correct this on your own. You may give him the wrong signals and make him worse. This needs to stop before he hurts someone.

It sounds like you have a dangerous situation going on. This is too big of a problem for a quick answer on the forum, but I will tell you that this is going to take a lot of work and time, and may never end up the way you want it to. I really feel that you need to ask your veterinarian for a referral for a good behaviorist in your area. If this is not someone you can devote some time and likely financial resources to, then you may need consider not keeping her. I am sorry you are experiencing this, I have been through something similar and it is very difficult. In the meantime I would order her a basket muzzle to keep on her when others are around to lessen the likelihood of her injuring someone. Best of luck and thank you for using Pet Coach.

I'm sorry to hear that you're having this problem with Runt! Aggression towards housemate dogs is a complex behavioral issue that can have a variety of different underlying causes, so it's hard to give any specific advice without being able to evalaute the dogs in person and get a much more detailed behavior history. Because of this, I would strongly recommend getting in touch with a veterinary behaviorist who can do a full assessment of the situation and help you put together a detailed plan to address the aggression. You can search for one in your area here: www.dacvb.org In the meantime, the best advice I can give is to keep the attacking dog separated from the other dogs in your household until you are able to get a behaviorist in to help. This will help keep the problem from escalating, and keep any of the dogs from being injured in the meantime.
