Dog aggression can be a very big problem in alaskan malamutes especially with dogs of the same sex.
EX: male with male ,female towards other females. It is more of a problem with male to male but there are many female dogs too that display aggression towards the members of the same sex.

Dog aggression should be worked on as soon as you get your alaskan malamute puppy. You can start by socializing him by taking him to public places where other dogs frequent such as the park or beach. Take him to neighbours and friends who may have dogs of their own. Absolutely take them to junior puppy classes. This is an excellent arena for social learning for your your malamute. Socialization is very important. While out and about your puppy should never be allowed to growl or exhibit aggressive behaviour ,it will only encourage him to continue his aggression every time you step out , which will prove to be very unpleasant when he is bigger and you need more physical control over your dog. While we are speaking of growling ,never under any circumstances let your puppy get away with growling at you or anyone . Correct such acts immediately with a loud no and a quick flick under the chin or a quick jerk of the lead or collar if you have him out on a lead.Your alaskan malamute puppy should never think he has the upper advantage in any situation . A malamute will absolutely take advantage of such a window !!!

As for dog to dog aggression when you are out walking and your dog is passing other dogs,your dog who may normally be playful but one day when you least expect it, a tool of aggression towards another dog. It may be he is jealous or being protective but it is likely just plain out dominance behaviour . This attitude change if never seen before by you generally takes many owners by surprise. The story is always the same ,"What happened to my dog , he has always been so playful with the neighbours dog or other dogs when we walk in the park , then the other day he just went nuts and outright attacked Fido , his playmate next door ,and today at the park he won't stop growling every time he sees another dog". This is common . It usually happens when the dog is around 1 1/2 and more readily seen in alaskan malamutes who have not been neutered or spayed. But it's not the rule as many alaskan malamutes can be neutered and spayed and still exhibit these this type of changed behaviour.

At this point it is necessary to stress the need for your dog to always be on a leash when out walking . If you have been lulled into thinking that your kind and loving malamute would not hurt a fly and is ok to run off leash , think again !! Always leash your dog when going to public places . It is not only dangerous for your dog because he may run across the road unexpectedly but also for the safety of himself from other dogs and to keep other dogs safe from him. Remember ,you have a big dog there and if he bites it will be a big bite . By -laws in cities are getting very strict these days when it comes to dog aggression so please leash your dog even if he is the kindest dog in the world. Accidents happen ,that is why they are called accidents. I have run across people who have let their malamute roam about the mountainside thinking that it is natural . Then call the dog aggressive and mean and stupid because they start getting complaints from neighbours that his non neutered malamute who is running at large is upsetting other dogs and showing aggression to a few. I ask you is it the dogs fault or the stupidity of the owner? Many problems relating to dog problems these days is owner related and the lack of skill many people seem to have when raising and bringing up a dog in todays society . This problem must be corrected in the future if dogs and animals are going to continue to be a welcome in our towns ,cities and villages. Breeders can play there part by providing potential new owners not only information that is positive and wonderful about their given breed but about the potential risks and downfalls also. I say take the rose coloured glasses of people and let them see all . Then they can make a far better educated choice when deciding which breed is for them and if dog ownership is truly what they are ready for.

Now lets get back to aggression. If your alaskan malamutes is prone to chasing or is known to start a fight as I said before he should always be on a leash . When you pass another dog ,you can walk as far away as possible from the other dog ,that means crossing the street to the other side if necessary. If that is not possible have yourself between the 2 dogs so that neither can reach each other. In both cases always remember to have a good hold of your dog in case he should attempt to lunge. When you hear a growl and sometimes you may never even hear it but you can sometimes begin to feel it through the collar vibrating ,give the lead a sudden jerk. This will halt the growl and let your dog know that this is not acceptable behaviour. Then quickly walk away from what he perceives to be his enemy . Don't sit or stand around for him to change his mind as it may progress to something uglier and may lose control of the situation where then you have the lost the upper hand the opportunity to teach the lesson. Once you have walked quickly away from the situation and he has stopped his growling ,stop and praise him if he has corrected his behaviour.

Do's and Don't Tips

Don't hard hit or punch a dog for acting aggressive and lose your temper and go wild ,use your voice mainly to indicate you are not pleased and firm handling.

Do remember that prevention is better than a cure ,teach your alaskan malamute puppy as soon as he enters your home.

Do teach your puppy the rules to follow and be consistent

Don't leave your dog on it's own so long that it may become bored and engages in improper behaviour such has barking, howling , and working on escape routes where he can do much damage to other pets or livestock in the area

Do give lot's of praise for corrected behaviour .
