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!!

    I recommend getting your pet in to be seen by your veterinarian right away. Continued vomiting and lethargy together are very concerning and can lead to dehydration and electrolyte imbalance as well as low blood sugar. She might have eaten something that either disagreed with her or something that has gotten stuck somewhere in her gastrointestinal tract. She could be sore from a hidden injury you are unaware of, she could have been exposed to some sort of toxin or irritant in the environment or this could be early signs of another condition or disease process. Your pet may need IV fluids to help support her system and to be fasted at the same time in order to give the gut a rest. Your vet can do an exam, blood work and possibly x-rays to determine the cause of the illness and suggest an effective treatment plan.

    It sounds as Shadow is suffering from a gastrointestinal condition, possibly an infection. it could also be due to ingestion of a foreign body material. i would recommend taking him to the vet the first chance you get, he will need to be checked first, if the vet thinks it's a simple gastrointestinal infection he will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better.
