5 month old
I have a solid black, 5 month old GSD and his ears are not up. I'm not 100% sure if he's purebred but the people we got him from said he is. He has traits and the body structure of a purebred, but his ears are floppy. They go up when he tilts his head or when a breeze outside blows them up, though they fall over almost right away. He has tons of bones to chew, and we used to give him milk and mix cottage cheese in his food, though they're still down. Suggestions or comment on how I can get them up? Or if he's even purebred?
