That is strange and different than I was picturing, so thank you for clarifying... but still, the answer is the same. Management & Prevention is best. It will be a bit of trouble at first, but you must be consistent to break the cycle/habit. Sounds like what is called re-directed aggression. The neighbor dogs grumbling and snarling on the other side of the fence may build up some frustration in your pup since he can't jump into that fight, he comes in and attacks your other dog. It sounds strange but it is a real thing that happens with both dogs and cats. If it were my situation I would (A) not ever let your two dogs out in the yard together in case the neighbor dogs get into a fight and your Dobe attacks your female and (B) when you let one dog enter the house from outside always always always have your male pup on a leash. Instead of trying to "catch" him as he enters, go outside & leash him up and lead him in. Put him on a down by your feet or put him in the crate to de-escalate. If your female is outside, leash him up before you let her in & don't allow him to sniff or "talk" to her in anyway for a few minutes - watch his behavior at all times. He needs to learn before he gets to be an adult that what happens on the other side of the fence is not his concern. If at all possible turn him out when the dogs next door are quiet. In fact, if they did not use to do this, and they just fight when your dogs are out, it's possible they are attacking each other because they themselves are frustrated that they can't get to your dogs.It's weird. They get along all day. They sleep on the couch together with us in the evening. Mostly when we have aggressive issues is when they come in from outside. It doesn't matter if they are coming in together, if she's coming in or he's coming in. As soon as they are both inside he attacks her. It seems like play for about 1 sec then escalates immediately. We have a very large back yard so they go out often alone. I accompany them several times a day and play after their done pottying. Ball, catch or just crazy doggy games my girl has played since she was a puppy. It still doesn't matter as soon as we enter the house if he isn't grabbed and crafted he's after her.
We have been trying to catch him as he enters and crate him for 10-15 minutes. Then they are fine till some one goes out again.
I've noticed he's worse when the neighbors dogs are out (other side of our fence) those dogs are aggressive with each other all the time. Is he trying to imitate them? Why only upon entering the house?
Is she 8 years or 8 months? He was too young to be neutered at that age but that point is moot now that it's said and done.She is 8 he is almost 7 months
That is a good opportunity to build the puppy's focus on you by playing with a ball or tug and turning his attention away from the neighbor dogs. We all have done this with our Dobermans because they are naturally curious about other dogs, but we teach them to focus on their people instead. This is the basis for having recall when the dog is off leash, and generally much safer for the Doberman so that they aren't approaching people who will be afraid of the breed.They have doggie doors so as soon as they hear ours they are out. I try as soon as they get out to bring mine in.
Yes, as long as you are doing something along the lines I mentioned in my initial answer about day to day training. Also very good advise by @Kaiser2016 about playing with him in the backyard while the neighbor dogs are out. If you do this I'd keep a long line on him so if he ignores you for the dogs you can reel him in. In other words, don't set him up to fail. You call, he comes to you even if you have to bring him in with a long line. Then reward big time. If activity is too much while the dogs are outside, you might just take him out on a leash, sit down in a chair and do the "look at me" game with food. The point is him focusing on you under distractions. At this age he should sit, down, recall and go to his place (a bed or crate) in the house and stay. Not perfectly, but have a good concept of all these things on command. Then work on duration etc. Try to make every lesson fun with lots of food rewards and alone time with you without the other dog. Group obedience lessons with other people and dogs is always a good experience for them to learn to listen to you while other dogs are nearby but in control by their handlers.So other than leashing him to come in we are on the right track?
My doberman male puppy is starting to act agressive to our female. She is 8 he is almost 7 months on the 14th of Jan. He was altered in Oct. What can we do? We can usually distract him with toys, but don't like the aggression
Is she 8 years or 8 months? He was too young to be neutered at that age but that point is moot now that it's said and done.
At 7 months he is getting to the challenging age so you need to stay on top of his behavior every minute so he knows he's not alpha.
My housemate had a 5 year old intact female when I brought home my Doberman puppy. My puppy completely dominated her within 3 months. So I had this 5 month old (female) doberman puppy, just wanting to play, but rough play, and dominating, paw-slap, body-slamming play. The rule was if one dog is not having fun it all gets shut down. They get along fine now, but that first year was hard. We kept waiting for the older dog to say enough is enough, but she never would take that initiative. She wasn't afraid of the puppy, just didn't like her much. So we humans had to constantly intervene, mostly prevention which was never let the two dogs loose together without supervision. And that rule still stands today because they are both intact females.I can't help but be curious why the adult female has not already explained that to the pup. In the normal way that a puppy would definitely understand coming from an older and well established in the home dog.

Whenever we bring a new dobe home to the existing dobe, we make certain that the new kid is kept in line....many times the existing dog will not take charge, and we felt that they were here first, so protect them in a sense until the pup gets a little older and has learned it's place. When the first dog sets the tone, it's much easier![]()

Unfortunately, as observed by Dr. Stanley Coren in Psychology Today, the latest peer-reviewed studies show the behavior changes in female dogs created by spay are not beneficial as generally asserted by vets. In fact, the studies show that spay actually increases aggression, fearfulness and anxiety in the recipient, as well as making them more difficult to train.

Increased owner-directed aggression [64]
Increased reactivity to approach by stranger (German shepherd dogs spayed between 5 and 10 months of age) [65]
Increased fearful behaviour in Labradors in response to loud noise, unfamiliar objects approaching on or near the sidewalk, and approach by unknown dog that is barking, growling or jumping [66]. (Fearfulness of approach by unknown dog that is barking, growling or jumping was more pronounced in dogs spayed after puberty.)
Last cycle here the time difference in starting was measured in hours and difference in finishing was only a few days. Experience tells me that if they are not in sync to a certain degree - one may be having some sort of health issue that needs looked at (would definitely be having thyroids checked for example here).
