I came home from work to find a puddle of green goo in the corner of Penelope's kennel. I called my husband to see if she had a greenie treat before he left for work. Yeah so that is what the green chunks were. Then, I had taken my girl out twice and she was playing around inside. I gave her some more water. I could hear that she kinda gagged. Soon after the heaving came, she threw up foamy bile three times. I was very worried. I put her in the kennel so she would let me clean things up without her getting in it. I gave her a few pieces of kibble as her stomach was empty at this point. Should I be worried about this or could she have just had an upset tummy from the greenie? I can see that she that she didn't eat much this morning. My husband left her food dish out away from her. She ate fine last night.
