Mom refuses to get our dog training before 3-3-3 is up
I'm at a loss of what to do here. We recently adopted this beautiful girl named Juno the GSD to be a family dog about a week ago. She's anxious, startles easily, is terrified of loud noises (storms and fireworks), doesn't really care about most foods, and is INCREDIBLY reactive on leash. Dogs, she gets excited and aggressive towards. Men, she gets fearful and aggressive towards.
We have a four person family, my adoptive parents and my younger sister. I am the one who spends the most time doing things with her. Walking, and playing fetch. I do over 50% of the walking, and 100% of the playing. As such, I notice her issues before anyone else. And she's more fond of me than anyone else, which mom views as a problem.
Juno is only motivated by walks. It's literally all she wants to do. It's her favorite thing in the universe. She gets excited just from hearing me say the word "go". But when we see one of her triggers, she goes crazy. Lunging, barking, twisting and sometimes squirming and screaming like she's dying. I've brought this up to mom, who's in charge of the household and thus makes the household decisions for the most part. I recommended getting Juno training, as her visceral reaction to men scares me, and she isn't food motivated at all. She freezes up, not moving no matter how I try to get her attention, then she lunges and barks like she wants to kill.
Mom refused to hear it. She said all Juno needs is time, to give it the good old 3-3-3. I said it's unfair to wait if she's essentially having panic attacks when she sees a male stranger, since that's something that happens often on the streets around here. She wouldn't listen. She seemed more concerned about the fact that Juno won't come to everyone when called, and only comes to me. I think it's unfair to expect her to come to everyone when not everyone has done things to bond with her in the ways she likes. She doesn't trust them yet, and I don't blame her.
Her recommendation was for me to stop walking her.
Do I need to just give it time? Is this something that will probably go away in a couple more weeks?
