We are fostering a newly found lab mix puppy. We estimate that she's approximately 4-4 months old. We've had her since around 2pm today and she has done nothing but sleep. She is not playful in the slightest. I'm concerned only because she shows no interest in eating or drinking, playing with our resident lab and she has yellowish-green discharge coming from her eyes. She also vomited foam earlier today --- it mostly stayed around the sides of her mouth because it was all foam, not much substance besides the grass she ate to make herself throw up (presumably) right before she vomited.
