Why is my 8-month-old dog aggressive or excited around other dogs?

I'm sorry that you're having this problem with Cssh! Aggression issues between dogs can be very complex, so without being able to actually meet him in person and observe his interactions with the other dogs, it's very difficult to say what might be causing this. Some dogs simply don't get along well with "new" dogs once they have grown out of their puppy stage - this could well be the case with your dog, since he's about 6-7 months old now. This isn't necessarily abnormal, but it may mean that your dog is not a good candidate for casual socializing with strange dogs. If you want to try and get a better idea of what may be causing Cssh's aggressive behavior and see if anything can be done to improve it, I would recommend making an appointment with a veterinary behaviorist - he/she can evaluate your dog in person and help you understand exactly what is happening. If needed, they can also help you put together a detailed plan to work on the problem. Your veterinarian should be able to find out where your nearest veterinary behaviorist is located, and set up a referral for you if you wish. In the meantime, I would recommend not allowing Cssh to interact with any dogs that he doesn't already know and like since there is a significant risk that he will continue to behave aggressively, which could cause injury to him or other dog.

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. Certainly male dogs who are not neutered are more prone to fighting and aggression. Neutering him may help but it will not likely solve all the problems. Best of luck.

Alaskan malamutes are beautiful dogs!! Based on what you describe, I am worried that Ace is trying to be the dominant leader of your family. Hitting Ace also can make him scared and defensive. I strongly recommend neutering him now to eliminate the testosterone hormone that has some contribution to this behavior, especially around other male dogs. I also strongly recommend finding a trainer that can help you regain control over him in a non-aggressive way. The trainer will give you different training exercises to do with Ace to help him act better. This will be a slow process, but it is important to start soon and learn more about why Ace is acting this way and the steps to curb it. If this behavior escalates, his size can make him a dangerous dog! Good luck and thank you for using Pet Coach.

Before resorting to medication, try getting him into an obedience class. This will teach him to look to you for guidance and see you as the leader instead of the other way around. Neutering can help also, but he may be a high energy dog that needs lots of physical activity and mental stimulation to be better behaved. He is young so this is the perfect time to teach him what correct behavior is. Take him for lots of walks, go for runs, play fetch, arrange playdates with other dogs so he can roughhouse, teach him tricks, anything and everything to tire his body and give his mind something to do besides think of ways to get into trouble. A tired dog is a happy dog. It may be a stage that he needs to outgrow and lots of activity will help. If all this doesn't help or not enough, ask your veterinarian what they recommend.

Unprovoked aggression can have many causes. You don't specify whether or not your dog is neutered, but if he's not, I would consider it very likely that his aggressive tendencies are related to testosterone, and schedule surgery to get him neutered, as removing the source of testosterone (i.e. the testicles) will help tremendously in controlling his aggressive tendencies. If he is neutered, then it's likely that his aggression towards other dogs is rooted in fear. He will need some careful training to help to reverse these feelings, and it may be quite difficult, but is certainly possible. Talk to a trainer in your area about starting with a good general obedience class, which will improve not only your bond but also his confidence level (and thus reduce his fear). You'll have to work to reward him for good behavior by using a small delicious treat to gain his attention and keep him from trying to go after other dogs on walks. In the meantime, always keep him leashed when he's outside in order to protect him as well as other dogs.

I'm sorry you are dealing with this problem! The first thing to do is neuter Loki. His aggressive behaviors to other male dogs could be due to the hormones produced from being intact. Intact male dogs will fight to protect their territory and for females. Neutering him can help reduce the aggressive tendencies. After that is done, I recommend getting him in with a professional behavioral expert. I never recommend owners work with aggressive behaviors on their own due to the serious risks to safety, and it is something that is best left to the professionals. A behavioral expert can work with Loki and you on his aggression, and can help train him to reduce it. Good luck, I hope this helps!

Now is the best time to neuter them both. Neutered males are more docile and make better pets. When they reach sexual maturity at around 6 months and their hormones go into full swing so to speak, they may act aggressive toward other males and want to become dominant in the household. If you wait too long, neutering will not help. I suggest neutering all dog sin the house as soon as possible, then the hormones will die down in a few weeks. At this time, implement a training program with a trainer or by doing some research. The behavior will most likely get better, but that is not definite. Neutering with combined training is your best plan to change his behavior. .
