Is same sex aggression a problem in all breeds?

[Pippin8]

We are thinking of getting pippin pup a playmate in the future. Would another bitch be unwise? Also what would be the best age to introduce a new dog (she's 5 months at the min)? We were thinking of waiting until she's at least 1, we would be looking at getting an older rescue dog.

We always choose male dogs and also always have two dogs we've never had a problem with "same sex aggression".

Outside of individual personalities, which can always have an effect - no, it is not the same in all breeds. Some are known to rub along well in any size/mix of groups, others are strictly one companion of opposite sex to be safe.

There are always people who will say that theirs get alone fine, but in general the best view is to take advice from those who have lived with multiples of the breed as to whether it is a general issue.

The advice I had from my dog's breeder was to make sure the first dog's training is rock-solid before introducing a puppy as they will learn good and bad habits from each other. She said the best age gap was 2-3 years - old enough to be relatively sensible, young enough to enjoy playing with a puppy

If we get another dog it would be a bitch as although my dog is not aggressive, all his best doggy friends are girls

I can only speak from my own personal experience with males.
Our family have always had 2 of different breeds,never had a problem at all.

I was a bit dubious this time around as my young lab was only 4 months old when we rescued a 12 week old of a completely different breed but they have been fantastic from day one,completely inseparable.

I have friends who have bitches who've never had a problem also so I suppose as with most things dog related it comes down to the temperament of the dog itself.

We're a multi dog household, and have been for around 10 years. During that time we've had all sorts of permutations and combinations of boy/girl, both our own and fosters. Currently we are 3 girls and 1 boy. All absolutely fine, and the girls are adorably snuggly with each other. We've had individual dogs who haven't got on with others, but I've never seen a consistent gender pattern. One of my best friends is also a highly experienced foster carer - she has two permanent bitches of her own, plus various combos of foster dog - can be either dog or bitch, and sometimes more than one. Not usually any problems. And her two permanent girls are extremely companionable and love nothing better than piling on to the sofa together in a nice lurchery tangle.

I've have always had two dogs at a time I found two males work well and also one of each sex, but two bitches I would not do that again.
they barely tolerated each other and at least once a month would come to blows.
When one of the females had to be pts ( health issues)we got a male dog and the remaining female was great with him.
I think some of it is the breed as our female was a Japanese Akita and I've since been told they don't get along well other female dogs.

[Whitney168]

No personal experience with any of these breeds, but by reputation ... yes, Akitas one of the breeds well known for same sex aggression, along with the likes of Staffords, Dobermanns (males), Boxers (males) ermmmm .... brain not in gear yet.

Those dogs which are traditionally worked in groups tend to rub along well - so the gundogs (Labs, Spaniels), hounds.

If we had a second dog we would go for a bitch purely because Eric shows a definite preference for bitches. He also prefers light coloured dogs so would bare that in mind too. In time your dog might express a preference too.
