Looking to rehome family dog (Nipomo)

This is Dakota. She’s 3 years old and I’ve had her since she was 8 weeks old. Cattle dog mix and Was told she has German Shepherd and German short hair pointer as well. She weighs 45 pounds and is healthy up to date with shots and spayed. She has been a really fun dog. Has lots of energy and is up for any adventure, but also has a good off switch and can chill in the house most of the day. She is not destructive at all; doesn’t chew on anything she’s not allowed to. She is really good with kids, especially considering her high energy level and prey drive. She’s really good with and protective of my young kids/toddlers. The reason we are looking to re-home, is her issues with reactivity. She is very protective of the house and yard and we live in a pretty busy neighborhood. She looses her mind when any delivery truck drives by as well as some other trucks and some people. The issue has been consistently getting worse and the list of her triggers growing. She see’s everything as a threat, and we’re concerned it may escalate to aggression. She has snapped at some grown men out of being protective of the house and fam. Never has bitten anyone. Due to our busy schedule with young kids we don’t have the time and focus to properly recondition her with these triggers. She needs to be in a neighborhood that is more quiet or more rural than our busy street where her worst nightmare (the mailman) doesn’t drive by 5 times a day. With work, she could get better and be a fantastic dog. Other info She’s a great hiking buddy and loves trails Pretty good off leash when hiking Smart and responds to obedience training She’s not good with cats. Good with most other dogs. Just other high strong females like her she doesn’t mix well with.
