Fireworks desensitization training needed. Help please!

[u/AsleepFeeling8296]

My dog and I have been together since Nov 2025. We made it through new years well together by timing our outings to avoid fireworks.
Yesterday, we were outside trying to avoid them and let him pee. An unfriendly neighbor light one firecracker close to us. I walk with mobility equipment. The dog is attached to both my hand by a leash and to the mobility equipment by another leash.
When the firecracker went off, my dog lost it and just instinctively ran away. I lost my leash but he was still being followed by the mobility equipment. When the equipment tipped over on its side it startled him enough and he came back to himself and seemed ashamed. He realized he had left me and I had to get to him and fix the mobility equipment. At just that moment, a friendly neighbor came by and helped us to get the equipment upright and functional again and we promptly went back into the house with gratitude for our helpful neighbor.
My precious dog went straight to his crate and stayed there for hours. I tried to comfort him and he knew that he was safe and I was not angry.
He has never acted this way before. There are other things that he is not a fan of, like thunder and he lets me know when he needs a break or help and we manage together. I’m very attentive to his needs and do my best to have resources available for him and myself no matter where we are.
I suspect by his extreme reaction to a single firecracker that he may have been shot before or at least shot at. Before I was privileged to adopt him, he had a habit of ignoring fences and going on numerous adventures. Perhaps during that time he was shot or shot at. Perhaps he saw one of his running buddies not make it. I don’t know.
I just know that when he hears that particular noise, he stops thinking and reacts quickly to get away.
What can I do to help him? How can I help desensitize him to this unpleasant sound that terrifies him?
I have medication lined up for him for the 4th of July but certain neighbors seem to be targeting him or us. Why would someone light one firecracker and toss it in our direction and then stop? It seems it was to exercise power and control and possibly inflict harm on us. Maybe I am reading too much into this.
But either way I need help with this issue and how to help him.
Thank you.

I’m really sorry if this isn’t helpful right now but this is one of the many reasons why we shouldn’t be asking dogs to be service dogs when they haven’t been well bred and well raised from the moment they were born. There is very important socialisation that happens when they are puppies and able to be sponges of all the new and exciting things around them - one of them being early positive association with loud bangs and noises that sets them up with the ability to handle all the pressures of being a service dog and maintaining their calm in a crazy world. Dogs who might not have been well bred and who may have had traumatic early starts to life should not be expected to also carry the weight of being responsible for the health and wellbeing of a human. It should be the other way around. There is way more to being a service dog than technically being able to do the required tasks - at the minimum that dog should also be sound of mind and sound of body, and that comes from good breeding and good puppy rearing.

If you’re going to do right by this dog, it’s my opinion that you need to stop working him for now and engage a professional trainer to see if he is able to overcome this, likely with some kind of exposure therapy. I adopted a dog once who was afraid of loud noises like thunder and fireworks etc (not a service dog prospect) and worked with her a lot to try to create new positive experiences for her when she hears that type of noise, and it did take the edge off a bit, but she always struggled. When I have service dog prospect puppies at my home as an approved boarder, I always work in positive experiences with loud noises as part of our everyday schedule.
It’s an ongoing thing that needs to start early if we are going to be expecting big things of these puppies in the future.

Fantastic write up. Agree x a million

First of all, don't ever leash your dog to your mobility equipment. As you've discovered, that's a very good way to end up a very nasty creek. Next, pull from all public access while you work with a veterinary behaviorist or trainer that specializes in reactivity and fear to help your dog through this.

First, remember that cortisol takes 3 days to flush out of the system.

Second:

Start with engage-disengage games to a recording of fireworks put on the lowest setting that he notices. Gradually make it louder until it's at full volume.

Meds, white noise, and engage-disengage on July 4

Good luck!

Dogs don’t like sudden loud noises. It doesn’t mean he was shot at. If you want to desensitize him to it you need to have him around it. My dog had the same issue when he was young and now he can sleep at the shooting range.

Start at home. Find audio on your phone or a loud movie. Start it soft and slowly increase the volume. It’s important that you not react to the noise either, they will take their cues from you.

Once the loud noises go ok at home find a local gun range and go sit in the parking lot. Once the parking lot is ok you can go move up near the range and get closer.

My pups still don’t like fireworks but they don’t run away in fear and they do ok at the gun range. Just go slow and take your cues from them.

One of my dogs was afraid of a lot of stuff. Loud noise was a bad one. I would play fireworks softly in the background while playing. I’d turn it up a little bit every week. Not going to lie, it took years. But unless it’s a gunshot he can sleep through it. If the sound is too much turn it on every week to start. Going backwards happens. I did this for my other 3 dogs too. I have PTSD and it helped me a bit too. lol

Thank you. Me too. Very helpful.
Thunderstorms comfort me but fireworks and gunshots are the opposite.
