Bullmastiff able to live with another male dog?

[Jadotha]

Ditto to what Akbul asked! We have never neutered our males and have always kept at least two at the same time in our household. Now, admittedly these were not Bullmastiffs, but rather IWHs and GDs, and currently an EM and an IWH -- (who came to us neutered when we rescued him. He is the one who is not fond of other males, though he gets on well with our Em, Boris).

Boris's best friend, with whom he has frequent long play-dates, is a 3 yr old Bullmastiff. They get on brilliantly.

well yes, spay/neuter will help eliminate reactions to a bitch in heat (though not always! I even know of neutered, EARLY neutered, males who've tied with a bitch in heat never mind fight over them!), but thats not the same as "same sex aggression" really, same sex aggression has to do with an intolerance of dogs of the same sex in general, and sexual status has very little to do with it.

male dogs for the most part are more aggressive than female dogs due to hormones , i'm gonna guess testosterone ? , i can only imagine "same sex aggression" whatever that may be is also hormone related ...... i had a very aggressive male bullmastiff who was in numerous kennel fights . at 7yrs old he was neutered due to recurring prostate infections , he never had a fight after that ...........again just my take on my experiences ........ the fights with the sisters never happened when neither was in season .......

My female BM was a wicked witch, and MUCH more nasty than my current male BM is. My boy developed into same sex aggressor at around a year. Small dogs are fine, females are fine. Large males are targets.

Same sex aggression is an intolerance of dogs of the same gender, it has nothing to do with dogs of the opposite sex being present or not and is not respective of the sexual status of both dogs.

I'm not saying that aggression is NEVER driven my hormones. But true same sex aggression isn't. For example TMs frequently have problems with same sex aggression. Males and females both. And it makes no difference whether either or both dogs are spayed/neutered. To the point where many breeders will flat out refuse to sell a (for example) male pup to a household already containing a male dog unless the new owner has experience managing similer problems.

And yah, female TMs are often considered more aggressive and guardy than the males.

I really, really appreciate all the responses that I've gotten. My little guy is the most submissive dog I've ever seen, so I don't think I'll have an issue in terms of him trying to challenge my BM. I wouldn't leave them alone together unsupervised even if there was not a single chance of an issue just because of their huge size difference, and I do have my BM crate trained and baby gates put up so that my little guy can get away from all that puppy energy if he wants to.

As far as neutering goes, I'm still not entirely sure what the best course of action is. We waited until 18 months before neutering our dane, and he didn't really love other big dogs (goldens and poodles especially for some reason) but never had a single issue with our little dog.

 

[ruthcatrin]

Its far healthier for him to wait till at least 18months if not older.

You also have the age difference between the two dogs in your favor and you said it yourself, you BM is respecting his elder when he tells him to back off.

I, too, have an age difference between my dogs (although a female and a male). I don't know if it helped at all, but I was very careful to communicate to Zeek that Lila is the "ranking dog." She was fed first, came in and out of the house first, she got to choose her bone first, etc. We had a couple of minor squabbles in the beginning, but I made a HUGE stink with both dogs that that behavior was unacceptable and we have had no problems.

It must be working because Zeek has never challenged an older dog (males his own age...a few times ).

One of the things dogs work for is acceptance into the pack. Continue to teach him what is and isn't acceptable behavior in your pack. The need to belong to a pack is strong - it means their survival.

I agree with you my friend. I hate when people force it down your throat to have your dogs fixed. Having a dog altered will not stop same sex aggression.

The rescue group at the pet store HATE me.

I have two intact males( no they will not be neutered) granted they have their little tiffs now and again as I expect. However they are best buds and their favorite game is tug o war. A not so favorite of mine as I have to buy new toys....daily
