He is unequivocally a "mixed breed", yet in may cities with BSL, he would be labeled a "pit bull type". Other dogs with similar looks have been targeted before.
Number 6 is Baby. She and Tango are a study in contrasts. When I knew her, she was about a year old, maybe 40 lbs, unspayed, and completely untrained. Her owners lived several houses down, and for some reason thought that she'd stay in the yard, even though she was a untrained puppy and there was no fence. She used to run all over town, and learned quickly to run from people because they'd catch her and spoil her fun. I was one of those people, but I used Zelda as bait and lured her into the house and caught her multiple times. Once caught, Baby was very friendly and loved attention from people. She wasn't great with other dogs, and she and Zelda had words more than once, but nothing serious. I don't know what happened to her.
Number 7 I have no photo, nor did I ever learn her name. She was a muscular "pit bull type" dog that a family got as a young puppy. Maybe once a week the kids would play with her, which she absolutely loved. But she spent most of her time chained to a tree in the backyard barking at everything. She once got out of the yard and ran at me and Zelda as we were walking by. She didn't seem to know what to do; she barked, growled, cowered, play bowed, rolled on her back, sniffed noses and butts with Zelda, and otherwise acted unsocialized and under stimulated. She mostly ignored me except for a sniff of the hand and a brief wag of the tail. Then the owners came out of the house and hauled her back to her tree. That was my only interaction with that particular dog.
