My dog bites my husband but not me. Why is she aggressive towards him?

Hello, sorry to hear about Commander. Aggression may indeed by a difficult behavior to manage and very important as it can create a dangerous environment for himself and those around him. Here are some tips on aggression and how to manage this. Hope this helps and best of luck. Introduction Aggression is a common problem faced by many dog owners. It is commonly misunderstood to be based in dominance. In actuality, there are various reasons that dogs can react aggressively. Most commonly these acts are based in fear or anxiety. This handout, will attempt to help you differentiate whether your dog’s aggression is based in dominance or another stimulus, like fear or possession. However it is not meant to replace visits and discussions with your veterinarian. Common types of aggression • Fear aggression: Many commonplace human behaviors are threatening gestures to dogs, but their reactions are often times very subtle and easily missed by most people. Anything that can cause your dog to feel distressed or uneasy can illicit an aggressive reaction. Such things include: sustained eye contact, pressure over the top of the head, lifting the dog, bending over the top of a dog, certain force-based training techniques, or trying to take something of high value away from the dog. • Territorial aggression: Dogs can react aggressively when a person comes into an area that it regards as its home. There is often a basis of anxiety in dogs that have territorial aggression. • Possessive aggression: When aggression is directed toward a person that the dog views is approaching something of high value (food, toys, family members). • Redirected aggression: When the dog is frustrated by the inability to reach an object or person that elicits its aggression and instead acts aggressively toward a person that is within reach. • Dominance aggression: True dominance aggression is very rare. Most often aggressive acts are based out of another type of motivation. Usually what is assumed to be dominance aggression is actually based out of fear or anxiety. What is your dog’s motivation for its aggression? It is important to watch the body posture of your dog during a time of aggression to determine the underlying emotional state of the dog causing the aggression. Here are some examples of what to look for: Fearful or submissive postures • Avoiding eye contact • Lowered head and tail • T ense body posture • Ears to the side, back or down • Horizontal lip retraction • Licking lips • Yawning • Crouched body posture • Moving slowly or freezing • Submissive urination Dominant postures • Sustained eye contact • Ears erect and forward • Vertical lip retraction • Forward-leaning body posture

I'm sorry to hear that you're having this problem with Alfie! Owner-directed aggression is a complex behavior issue that really needs in-person guidance. In general, I can tell you that treatment for this problem typically involves identifying situations that tend to trigger the aggression - then either finding ways to avoid them, or working with Alfie to teach him to be more comfortable with these situations so that he doesn't feel the need to bite. All training should be positive and reward-based, as punishment often makes things worse over time and greatly increases the risk of being bitten. I would recommend asking your vet for referral to a board-certified veterinary behaviorist who can evaluate Alfie in person, and help you put together a detailed plan to work on his aggression issues.

Oh dear! I'm sorry to hear that you're having this problem with Onyx. Human-directed aggression in dogs is a complex behavior issue that can have many different causes, so I'm afraid it's difficult to say what might be causing this without a full behavior history and an in-person evaluation. This sounds like a very dangerous situation for you, so if you want to keep Onyx, I would strongly recommend making an appointment with a veterinary behaviorist who can evaluate him in person and help you determine what is causing this behavior. Aggression issues like this can be treatable in many cases with careful management and a good training plan to work on the problem, but this should only be attempted with assistance from a trained professional.

I'm sorry to hear that you're having this problem! Aggression is a complex behavioral issue, so it's often hard to give a succinct answer in this format. It would help to have more information about what kinds of situations seem to trigger the aggression, as well as some details about how your dog acts in other contexts. In general, I can tell you that most cases of owner-directed aggression like this are related to insecurity and guarding behavior over resources - like resting places, and sometimes food bowls or chew toys. Many of these dogs will bite somewhat unpredictably when lying next to their owners on a couch or bed. If you want to try and address this behavior, I would recommend making an appointment with a veterinary behaviorist who can evaluate your dog in person and help you determine what is causing the aggression, and also give you a detailed treatment plan to work on the problem. You can search for a behaviorist in your area here: www.davcb.org In the meantime, I would recommend avoiding situations that tend to trigger the aggression as much as possible - this may mean blocking Sam's access to the couch, bed, or other areas where he has tried to bite you. Punishment of any kind for this behavior is not recommended, as it tends to make the dog more defensive and worsen the aggression over time. Instead, if he growls or tries to bite, calmly walk away or call him to you for a treat to help diffuse the situation.

Hi there! I'm sorry to hear that you're having this problem with Buffy. It's not unusual for behavioral issues to take a few weeks to show up in a newly adopted dog - there is often a "honeymoon period" while they're still getting comfortable and adjusting to their new home, before these issues start to emerge. Aggression towards other dogs and humans is a complex behavioral issue that's difficult to address properly in a forum like this, but I can try to give you some general information that may be helpful. Treatment for aggression issues is generally based on identifying what situations tend to trigger the aggressive behavior - then either finding ways to avoid them, or working with the dog to teach her to respond differently using reward-based training techniques. If this is something you want to work on, I would recommend making an appointment with a veterinary behaviorist who can evaluate Buffy in person and help you put together a detailed treatment plan to address her aggressive behavior. For now, if the aggression only happens with dogs and people she doesn't know, I would recommend keeping her separated from visitors for now until you are able to get a more detailed plan in place to work on the problem.

I'm sorry to hear that you're having this problem! If this has been a fairly sudden behavior change for Elsa, the first thing I would suggest would be to have her examined by a vet to see if there may be a medial reason for the aggression - many illnesses including thyroid problems and neurologic issues can cause sudden mood swings and behavior changes like this, as well as anything that may be painful such as an injury of some kind, arthritis, etc. If your vet determines that Elsa is healthy, then I would strongly recommend making an appointment with a veterinary behaviorist as the next step. Aggression towards humans is a serious and complex behavior issue that needs to be handled by a professional who can work with your dog in person. The behaviorist will evaluate your dog and help you determine what is triggering the aggression, then put together a detailed training plan to work on the problem.

Oh dear! I'm sorry that you're having this problem with Billi. Owner-directed aggression is a complex behavior issue that can be quite serious, so I would recommend recommend asking your veterinarian to refer you to a veterinary behaviorist in your area - he/she can evaluate your dog in person and help you put together a detailed training plan to work on this problem. In general, I can tell you that the best way to deal with this problem is ny identifying what situations tend to trigger the aggression, then either avoiding them or working with her to teach her to be more comfortable with these triggers so that she doesn't feel the need to growl or snap. This would always involve reward-based training, never any kind of punishment as this is likely to make things worse. If your husband is petting her and she growls, she's asking him to stop - he should listen to her and leave her alone at that point, rather than continuing to antagonize her with more petting. This often leads to increased aggression (such as snapping or biting) from the dog, since her communications signals are being ignored. The behaviorist can help you understand why she gets upset in these situations so that you can learn to avoid them or help her be more comfortable.
