Our 4 month old German Shepherd mix got out of his crate yesterday morning. A clean casserole dish was on the stove and he broke it and bit a piece, cutting his lip and tongue. The vet wasn't overly concerned. Said he most likely didn't eat a piece because if he did he would be in a lot more pain. She said he was "sore and pouting". After the vet's yesterday, he drank some water and drank some food. He was obviously a little sore and wanted to sleep, but happy. Today, he is hardly drinking, refusing to eat, and is just not himself. He usually loves our walks and we play in the living room. He kept sitting down on the walk, and lagging behind on the leash, like he didn't want to be near us. He doesn't even want us to pet him and acts scared of us now. Is it possible he blames us for his injury...or is something else going on???
