Thanks for updating! I just wanted to compliment you on following through and being open to advice and other's experiences. Going to a breed knowledgeable kid free owner who understands Ruger is changeable and has shown unpredictability, complete with an injurious bite, was probably the only possible alternate outcome here. I hope all that is the case with the rehoming. I wish him and Ruger all of the luck and successes.So we made a decision to rehome him to a friend with another gsd and gsd experience, he has no kids, and doesnt work so has a ton of time to spend with ruger and he will has a gsd buddy!!! Hes been there since yesterday afternoon and is liking it there til it's time to go to bed and he is missing home so he whines but in time he will be ok. This was a much easier decision then to euthanize him as he really is a good boy except with my daughter. This was a dog I had an extreme bond with so it was a very hard decision that I shouldve made when he first showed aggression with her but she cried to keep him and it's just unfortunate that it took the bite to see he really needed a new home despite our love for him. Thanks to all for your advice ?
