The front dew claws should always be there, and some folks remove them at birth up to a week or 10 days. If removed later than birth-10 days, it's an actual amputation.
I find most our dogs are able to use their 'thumbs' anyway, and wouldn't remove them.
I have one dog who has his removed and he seems to wince when I rub that area.
I know it is off topic but I think "they" remove too many body parts from dogs.
P.S. I went through your thread and read your 'long story'. So sad but I'm happy you and your hounds and your GSD are together. It seems like it was meant to be. Bless you for opening up your heart...It takes a lot to do so. Believe me, I understand/know c:
I think he looks like he has a small amount of pit bull. The slight indentation in the middle of the skull, the large, round eyes, the heavy and broad face, and the broad chest seem consistent with pb/shep mixes I have seen. But I'd say he looks 15/16ths GSD.
