Why is my dog overprotective and growling? How can I stop it?

I hate to hear this is happening and unfortunately, it's impossible to know the real cause of the behavior without being able to observe it. 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. I also recommend to have Cezar neutered. Intact males tend to be more aggressive but again, aggression is complex and it may not solve the problem. Best of luck.

It is difficult to give accurate advice in a situation like this because to know the cause, you must be able to read the body language of the pets.

This is not unusual behavior as they are trying to work things out. I recommend to always supervise them together until you know there is not chance of a fight. Some dogs are more possessive of toys or food or their person and thats just how they are. Certainly not leaving toys down and only giving them toys when you are home to supervise will help. Do not allow them to steal each other's toys. Also, both dogs will likely think ALL the toys belong to themselves and not the other dog. If you cannot supervise then, you may separate them during chew times with their toys. Heavy daily exercise will help to get some of the energy out and this can help to decrease aggression. I also recommend to pick up some books about dog behavior so that you can recognize what the dogs are saying to each other. Lastly, there are several different training methods out there. You may opt to find a trainer who can come to your house and show you how to modify the dogs' behavior. Find a trainer who's style works with yours. This will take some time to condition the dogs and yourself. I hope this at least points you in the right direction. Please post again with any further questions.

Hi there. Any type of punishment for this behavior (which would include the use of a vibration collar to startle or scare him) is not recommended, as it has a high risk of making things worse over time. Instead, I would recommend working with a good reward-based trainer or behavior consultant who can give you some in-person guidance on how to address this issue. In most cases, we work with dogs like this by teaching them that good things happen (like getting treats!) when strangers are nearby. Once the dog is happy to see strangers approaching, he won't need to growl or act aggressively anymore. You can search for a qualified trainer or consultant here: www.ccpdt.org or www.iaabc.org

Situations like this are complicated and it's hard to give the best advice without being able to observe the behavior and walk you through things. Sometimes this can be true aggression. Sometimes this is related to Emma not wanting to be moved/handled. The latter can sometimes be treated with counter conditioning to provide a more positive experience that Emma will want to happen and thus will respond to.

Have your GF be the one who feeds Harley, and plays with Harley. Have a favorite toy that Harley ONLY gets when the GF hands it to her and plays with her. This does not mean Harley will automatically correct her behavior but it can help. Best of luck.
