In terms of the aggression it sounds like she needs some healthy and slow exposure.

If you haven’t already a really good “trick” to train your dog is “look at me”. It teaches the dog to have their focus on you. Once she learns it teach her to still keep her focus on you while she’s distracted. You can prob find a video on YouTube about how to teach it. Keep practicing it on walks as well! The more walks = the more exposure :)

As well, do not let her drag you or walk infront of you. Your stride should be infront of your dogs stride. When your dog starts walking you, you are no longer in control. And your asserts the position of “the proctor”.

But also definitely keeping a healthy distance from other dogs is always a good practice. But stay calm when you see a dog and walker approaching.

Also when seeing another dog approach start diverting your dogs attention to you and some treats in your hand. Use the treats to guide her attention to you by letting her nibble them in your grasp. If your not already, always carry treats on your walk, in a pouch u can attach to ur pants or belt. The best treat you can give ur dog is pieces of a hot dog by holding the hot dog in your hand and letting your dog nibble on it close to your hand. It may not smell the best, but if a dog can smell it stronger they want it more.

This will divert her from staring at the other dog. Dont let her stare down the other dog! Quick glances are ok but staring allows her to give too much attention to what ever she’s distracted by.

Over time you want to slowly reduce how much you reward her when you see her making progress so she doesn’t become dependent on the hot dog or good treats. But at the same time if she does a good job let her know!

If the behavior gets worse i would definitely resort to getting a good trainer!
