I have a 4 year old entire male German Shepherd. We go weekly

This answer was rated:

I have a 4 year old entire male German Shepherd. We go weekly to training classes and he is obedient so long as no other animals around. He has a problem with some male dogs which started 2 years ago, when he manged to open the gate from the garden to see our neighbour who was chatting to a couple with 2 other dogs, a fight ensued luckily with minimal damage! As a result I always muzzle him when out. He had not lunged or barked at another dog (or cat) when out for months, so I started to walk him off lead (with muzzle) and has not chased or gone for any other dog or cat. Then the other day I he charged at another dog and had to be physically pulled away. If he was the same with all dogs I could somewhat understand however it seems to be some dogs on some days and once he's had a problem with a dog he has a memory like an elephant. Any ideas?

Hi JaCustomer,





What is probably happening is that your German Shepherd is a dominant dog and doesn't have any problems with dogs that readily acknowledge his dominance. However, there are always going to be dogs that won't acknowledge him as the dominant dog or might test that dominance and to those dogs he reacts. Size also does't matter in these situations. Some of the most dominant dogs I know are little chihuahua.


It might also be triggered by the smell of the particular dog. He may remember a bad experience and that smell may trigger him to be more aggressive, but most likely it is a dominance issue.


I know you go weekly to training classes, but you also need to work with him daily practicing the commands you are learning. Training works best if you train at least 30 minutes a day (two 15 minute sessions). I would start making your dog work via the Nothing in life is free program (NILF). It is outlined below.


Obedience training serves to teach commands but also to establish you as the boss. As the boss it is your job to ensure no dogs bother him and to protect him. So definitely keep up with the obedience training.


Since it is intermittent, you will really need to pay attention to his body language. Body language should give you an idea if he is going to react to the other dog. Here are a few sites on body language for you to study.


Another trick you can use that many people do not know about is that if your dog is displaying dominant or aggressive behavior with the tail held high up, just brushing the tail down to a more neutral position (straight out from body or lowered) that can change a dog's mood to a less aggressive one.


If you can find a dog he reacts to consistently, you can use the bat method to help correct the situation. Read more on this here:

Thanks Jane,


You are correct he is an extremely dominant dog and as such I do follow the NILF program as a matter of course (just didn't know it was called that :)) therefore he has to work for everything!

I've been trying to pay attention to his body language and yes he generally goes rigid as a board if see's a dog he's really not keen on!

I'll up his training again, I usually do 10 - 15 mins once a day but will do more and the BAT is certainly worth trying if I can find a willing participant!

Kind regards



I breed rottweilers and being female training strong wiiled, strong, dominant dogs does require a lot of will power and training. It often means that the only affection we end up showing our males is in response to desired behavior. Remember to rate.
