My male gsd 10 months kilo. I fed him a quarter leg chicken last night. And when I woke up this morning there was vomit in his kennel. It was prolly a 1/3 of the quarter leg all chewed up in vomit. I took him outside for morning piss. And he wasn't as energetic as he usually is. Left outside for a couple hours to play fetch with him and he was fine. Left alone for a couple more hours and I came back with two wet spots on the ground w small pieces of chicken in it. Really worried since he's been throwing up multiple times. And his energy is quote abnormal.
