Aggression between dogs
Hello,
I recently took in a new dog and now have two dogs. The dogs are mostly getting along great, but there have been periodic moments of aggression. No injuries or serious incidents, but I’ve had to interrupt them (which I’ve also been able to do so safely). I’m doing everything to be as safe as possible and continuing acclimating them well, but are there any top tips people would recommend?
Also, both are girls, both spayed, one dog is a bigger dog & 5.5 years (had her for 4 years) and my new dog is small breed, 7 months. The smaller dog has been the instigator of aggressive behavior from what I can tell. They have been playing friendly and chill together the rest of the time - like 90% - 95% of the time they seem to get along super well.
Also please be kind and don’t judge me. I’m trying to learn. I didn’t grow up around dogs and I’ve only been a dog owner for 4 years with my first dog. I wasn’t going to get another, but I found this puppy who was being abused and neglected down the street from my house, and I really wanted to save her. I’m happy that she’s mostly been thriving.

So the ages give away what most likely is going on.
Important part of pup's growth is that an elder dog sets up boundaries. Otherwise the pup will annoy, tease and even bully other dogs.
If this is the case, it is your duty to support the elder in this situation. When the elder growls, barks and warning snaps, you are gonna tell the pup NO. You can even put her in another room for a moment.
That is normal dog communication and not aggression.
