My puppy is throwing up, lethargic, and eating grass. Should I worry?
Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Joie!
From your pictures Joie seems to be pretty sick. Causes for vomiting and lethargy in a young lab: foreign body ingestion where she ate something that is stuck in her stomach or intestines, a virus like Parvo virus especially if she is unvaccinated, intestinal parasites, toxins, etc. It is probably best to have her seen as an emergency today.
You can try to fast her: no food (and no grass) for 12 hours. Hold on water for 4 hours and if no vomiting offer ice cubes. If she continues to vomit while being fasted she should see a Vet today. If the vomiting subsides then starting tomorrow do "sip and nibble" of water and a bland diet of boiled chicken or hamburger with rice as small frequent meals. Feed 3 cups total per day. If she restarts vomiting with food then she should see your Vet.
Good luck!!
