Thank you everyone for the input. I was listening to vet, but the could have it wrong as well. I think the dNA check may be in order to determine what toexpect from him and to better assist him in behaviors.

His name is Max or Maxie. He is a sweet little guy who is full of mischief and energy.

We posted all over social media. We live in an area of many dumped animals. Out in the country away from town and main roads. We did get a local rescue involved. We have had him since early November and he has very protective behavior of me. I decided to not stress him anymore by switching families again. With his love of car rides and his love of lap snuggles, we figure he was either a truckers dog, or an elderly persons. The vet and the rescue agree that he is basenji/blue healer and he is roughly a year old. I wish we could have found his family, but he seems to be settling in nicely here. He is a great play mate for our youngest lab who will be a year on Valentine day. They are always roughhousing and running. Our older labs ignore him, but he tries to herd them all around the yard and the house.

Hello. I have adopted the cutest little terrorist I ever met. He was being chased by coyotes and my daughter saw a blur run in front of her car she thought was a fox. She stopped and he ran over to her car. She knew it was a pup and heard/ saw coyotes. Opened the car door and he hopped in. He lived in a very large crate in the garage for a bit as he was too aggressive with our other dogs (4 labs). We fostered and after he finally came in the house (almost 3 weeks) he is still quirky. If he is sitting on sofa with us he attacks the other dogs if they get too close. I was afraid others might put him down for this "aggressive" behavior not knowing his crazy beginning. I had to have surgery and he spent 2 days on the pillow next to me being a sweet protector and snuggler.. So I decided to make him part of our pack. He has some serious quirks with behavior, skittish, chews everything, slight over aggression toward other dogs, scavenger and food snatcher, and humps other dogs. He is neutered, about 1 yr old, mixed with blue heeler (lucky me) and I am doing research for his behavior mods. He did attack the chickens we have at first, but has since learned to just herd them around. The weather will warm up and that will help in training. Any tips would be great. He is a sweet little guy and he is a work in progress, but aren't we all.
