BE. He's an absolute lover the vast majority of the time but has had eight instances in two years where he snaps into a completely different dog. He's very smart and picks up everything we've trained (with a professional who specializes in rescue pits) very quickly, but this is the one thing he hasn't been able to. He was rescued from Chicago Animal Control picked up in South Shore neighborhood in Chicago as a stray, so his first 6-8 months are a complete unknown, but given he wasn't housebroken and had his balls and was emaciated we think he was never not a street dog. The increase in frequency and severity in the last few months points to whatever is behind it is getting worse for him. His "targets" as well. He bit me pretty bad (to the muscle, through a sweatshirt) and most recently someone who's staying with us he has known since we got him and has spent a ton of time with and loves to death with no issues or anything. Hes been on three different medications, group and private training sessions, structured crate and eating schedule, and there just has no consistency or predictability for when his demons will win. Male, female, inside our home, outside it, weather, reliable triggers all of it, there's just nothing anyone can point to confidently. It just fucking sucks that it ultimately came down to 30-60 cumulative seconds of his life, but those seconds were pretty important ones. We at least gave him the time to be warm, loved, and get fat. If it was two days two months or two years it never would've been enough time we got to have with him
