Introducing my agressive Boxer(1,5 yr old) to adopted Frenchie (2 yr old)

Well, ive got a puppy last month and it turned out that a friend of mine cant keep his dog, so ill adopt it!
My Boxer was also adopted! We are from Brazil, so please, enjoy the speech at the video, lol!
My Boxer has Agression problems, i mean: whenever we are walking with him his becomes like crazy, barking all along the walk and trying to bite dogs, pulling the leash, and everything...
A friend of my sister brought a pomerania ( 6 mo old) and they met already inside Boxers territory, it was all OK, no barks, no bites, just funny dog playing ( WTF? HOW???).
Then i got my puppy it stayed at my GF house for 3 or 4 weeks, it was 3 months old when it first got in my house (taped in the videos at 4shared)
you can see all that happened, but i took the puppy inside the house in his box, and put the other dogs to get to know it!
i tought Boxers tail was a little to much upside but it turned out all ok... at the first time my puppy just stayed for 2 or 3 hours...
for the other time the hole day.... and now hes living with us and they just have fun!!!

( i dont know if links are allowed, but id rather share all i have from this Boxer to make sure ill handle this case)


Now my main concern here is that this new dog is 2 years old, not a puppy at all... even older than my Boxer and he doesnt got basic training, he was living at the house courtyard forever....
i've seen many ppl saying that i should take them to a neutral territory but i think in this case it might be different....
i just wanna make sure that everything are gonna be ok!

I wanna thank you in advance! Here in Brazil we dont have much forums about dogs and at the ones we've got i havent got any answer even with all this videos and info about my dog.

This dog is coming to my house in something about 5 days and i hope you can help me!

Best regards

I would NEVER ever get another dog because my dog is dog aggressive. He was mostly fine with the other dog we had (he was already here when we got him), but still had really bad fights about food, toys etc.

I'd find that dog another home.

Have you seen my videos about the Boxer socialization with the Frenchie ?
They dont fight for food or toys... sometimes the Boxer even let the Frenchie take its food or toy.
But Thank you very much for answering that fast!
i hope we can find a better way to solve this problem.

Best regards

I didn't watch all of the videos. But, it was plain that he boxer was enjoying the puppy.

I noticed that you had the doxie in your lap while the boxer and puppy were on the floor. Putting a dog in your lap can instigate a rebellion with the other dogs, but your boxer didn't seem to mind. I think that your boxer is probably not as dog aggressive as you think. The fact that he misbehaves while on a walk is probably due to lack of training. Your dog feels vulnerable on the leash and makes a lot of aggressive noise to keep the other dogs away. It could also simply signal his excitement.

Let the dogs meet in a neutral area. A dog's response to a puppy is going to be different than his response to an adult dog. Your dog does not feel the need to defend his territory with a three month old puppy, but he may react negatively with an adult dog. Better safe than sorry.

Hello, first of all thanks for the answer!
Today when my sister was going to work someone passed by a stray dog and it went inside our house when the gate was still opened!
My sister took care of it and gave water and foot....
After a while she let the Boxer come into our garage, where this dog was ( it's a female) and even tought the Boxer got its back fur all erect they did well!
The main problem for meeting the dogs outside is that this Boxer makes very bad at the leash and as a courtyard dog, the other one has no idea what is a leash!!
The Boxer has had basic training and takes command very well while in our house and some like sit it would even obey while in a walk...
Im afraid just because i tought that if the first meeting went bad i might be almost impossible for me to take them together afterwards.
I tought that taking Pirata( the new adopted, 2 yrs old) blankets and leaving at the Boxer bed wouuld help a little!

I agree with all the above.

Well, as i see the Boxer show every signal of dominance, as it does while in a walk. I was very concerned about this problem and i went to a professional, who until now could not solve the dog problem. That is, this is not a problem whit whom it is getting its walks, but his mood in it....
Ive bought a gentle leader which should help me solving this problem but i know its not all!
Ive been studying a lot to become more confident while walking with him, i keep the shoulders and head up, calm and assertative, things like this, and even though it's changing its moods while in a calm area, it keeps the same behaviour while walking closer to other dogs...
Now as i really need this to work, id like to explain me or send me links with a how to do what ure suggesting.
Also i was not aware that taking the teckel in my lap would instigate any missbehaviour into the other dogs.... that could've been a problem...
So how do you suggest, exactly, that i should made this walk and meeting in a neutral territory ?
it seems to me every territory is the Boxers territory....
also there are 3 cases of this Boxer meeting dogs into its territory and not beeing agressive that way...
The other case was when a friend brought his pomeranian, maybe 5 mo old (i know, also a puppy)...
so please, help me out!

Best regards

You can use a friends yard for the introductions. Otherwise, meet in the park, but put your boxer on a long lead, like 20 feet, so he doesn't feel constricted by the leash. In fact, while in the park if you used a 20 foot lead and let your dog get some time to stretch his legs he may be better with other dogs he meets. He needs to meet other dogs without feeling you pulling on him. Boxers tend to be domineering, but they are not generally mean.
