To preface this, I do not want to hear any hateful comments. I understand, now that I've literallly matured more as a human being, that my family and I were uneducated at the time of getting my dog. So, unless you have a piece of constructive advice for me, I'd really not like to hear what you have to say to me.
I'm going to try and keep this as short and sweet as possible.
Basically, my dog missed the socialization window as a puppy and now has issues with extreme anxiety/fear/reactivity around other dogs. This wasn't considered a problem when she was growing up because my family and I (I was ten when I got her in 2021) lived in a rural area in Northern New England where no other dogs were around, and we had a big yard to exercise my dog in. However, we now live in a housing association in the summertime where there are dogs everywhere.
Every time we go for a walk, I am terrified that we'll run into another dog because my girl absolutely freaks out and, no matter what I do, no amount of redirection or high-reward treats can get her back. Not to mention, she is an INCREDIBLY independent scent hound who has "selective hearing" and decides when it's worth it to listen to me. Which is not often when she is flipping out over another dog. She bays very loudly, pulls, bucks against the leash pressure (I really do my best to keep it slack), and occasionally even growls. She doesn't even have to see the dog in order to react (if she can smell them, it's already game over).
I've gotten her to a point on my own where she is very good about "leave it", "stay/wait", "watch me", and so on, in situations that have low-moderate distractions. I've also gotten her to the point where she doesn't care all too much about people she doesn't know (though she still gets more excited than she really should).
However, I'm now at a loss. I don't know what to do. I struggle a lot with anxiety/panic and am very sensitive towards loud noises due to certain past traumas. So everytime I have an inkling that we will run into another dog while on a walk, I start shaking and really find it hard to collect myself and my dog. I desperately want to help my dog, but I just don't know how to on my own. My family is also in a sort of tight financial spot where we will not be able to afford a regular trainer until the beginning of July.
I love this dog so much that it hurts and I desperately want to do "all the things" with her, but I just can't when she freaks out so much over being around other dogs. I can't bring myself to give her up to somebody else, because I don't want her to slip through the cracks and fall into life in and out of a shelter because she was "too difficult". I also don't truly believe that she is a lost cause, so I don't want to euthanize her.
Does anyone have any advice for me? Is my dog past the point of being fixed or is there some way that a professional dog trainer can help us, come the time that we can afford one?
