Hi. My new pup is 9 weeks old yesterday. This morning I noticed some wattery greenish puke just outside her cage. She seemed her normal self all morning and I fed her as normal. A few hours later she started heaving and puked up her food. Then an hour or so later same again but just clear Sylvia but what looked like hair in it. After that she was great again playing and running around like mad. Gave her her dinner and about an hour later same thing, puked her dinner up. She isn't getting any other treats as yet. Again we noticed hair in puke. Could the hair be making her sick? She is now lying sleeping with our 8 year old lab and ok.
