My dog is lethargic, vomiting, and not eating. What should I do now?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | unneutered | 1 year and 3 months old | 3.307 lbs

Morty is very lethargic. He's usually very energetic, jumping here and there. Difficulty standing. Only drinks water, wont eat. Vomited more than 5 times already. Sallivating. Gums still pink. Vomit is brown fluid. Dad fed him brown rice with eggplant not knowing eggplant is bad for them. Vets are closed tonight. What can I do to alleviate his pain or discomfort until tomorrow morning when we bring him to the vet? Please help. Is the eggplant a factor in his lethargy, vomiting, and listlessness?

Thanks for using Petco Pet Education Center, formerly Petcoach! While some dogs are allergic to eggplant, most dogs tolerate it just fine and I suspect this is not necessarily the cause of his symptoms. Vomiting can be observed with conditions such as gastroenteritis, pancreatitis, dietary indiscretion, gastrointestinal foreign body ingestion and obstruction, among other possibilities. For this reason, I highly recommend that you have Voldemort evaluated by a veterinarian for further assessment and treatment as soon as possible as I am afraid he is likely becoming dehydrated. They would be able to check for these possibilities and also check his hydration status and give him medications to make him feel better. There is not much you can do in the meantime other than keeping water available at all times and not feeding him anything else until then. Good luck! I hope you find this information helpful.
