A bit of a variety here...DA due to same sex aggression, dog selectivity/reactivity, and dogs outside of the family (strange dogs).
Chloe is dog selective. She has to be carefully introduced to dogs before I can trust her to not pick a fight, and even then her fuse can be rather short at times. She doesn't like dogs getting up in her face and the only time she tolerates idiocy on another dog's part is when they are puppies. If a dog gets in her face or interacts with her when she doesn't want them to, she will go after them. Typically, every dog I've needed her to get along with (fosters/new additions) she's accepted after an introductory period at the least.
I've also dealt with in-home dog aggression in the way of same sex aggression. Chloe and Rose cannot be in the house at the same time or they will fight. They're okay in the yard, but the house...no way. It started of small, but it escalated to the point that if they see each other in the house they immediately go on the offensive.
I also grew up with a Malamute, Loupie, who was same sex aggressive. She got along with Blackie and later learned to tolerate Brownie (and then Rose), but she never got along with the other females all the time and I remember as a kid frequently breaking up dog fights between her and Rose. Loupie would only become aggressive when a resource was in question (food, affection, etc.), so we were able to control it to a degree, but never fully. Luckily it was never anything serious. However, she would seriously attack any dog that was not one of ours - out for blood attack, not just squabble.
Blackie and Rose were never really DA per say, but they didn't get along with dogs outside of the family. After a very cautious introductory period they would accept a new dog into the family (I don't think we ever really tried to get Blackie to accept an adult dog, just puppies, but Rose was okay with either as long as they were non-combative), but any dog outside of ours was to be driven away by any means necessary. They both were fine with ignoring dogs in public and neither one of them took horrible offense if another on leash dog sniffed them in a controlled setting, but they had no qualms about going after another dog. They never did any damage, though, it was mostly just show.
Cora isn't DA, but she is very fearful and territorial all at the same time, which doesn't make a good combination. She's great with friendly dogs and just melts into a pile of submissive puppy goo, but if a dog aggresses at her, she freaks out and aggresses right back. She has decided she hates our neighbor's dogs (don't blame her - they aren't friendly) and she barks at them whenever she sees them at the edge of our property. Given the option she'd take off after them. However, she did get loose once and took off towards them baying her head off...and then promptly started yelping and screaming and running back up to the house when they advanced towards her. Chicken dog.
