My 4-month-old puppy is not eating, lethargic, and vomiting. What now?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | unneutered | 4 months and 9 days old | 6 lbs

4 month old dog, not eating, lethargic, coat looks ok no marks. 3rd day now - does not play with our other pup just lays about. Acknowledges his name and very feeble tail wag. Some frothy vomiting at times. NO vet near here in Philippines to take him. What do you suggest? Dog does drink some water. Goes out in the sun to sit but needs to be carried back in - seems little disorientated.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Copper! I am so sorry that Copper is sick! Possible causes for Copper's symptoms are: intestinal parasites, viral or bacterial infections (especially parvo or distemper virus), toxin ingestion, congenital issue (liver shunt), dietary indiscretion (ate something gross), foreign body (ate something that is stuck requiring surgery), food intolerance/allergy. Sadly Copper needs a vet. Three days is a long time for a puppy to not eat and be vomiting. I understand there isn't a Vet nearby but without a diagnosis it is impossible to guide you on treatment. I would fast him for 12 hours and start a bland diet of boiled chicken or hamburger with rice. Feed him small, frequent meals and allow only sips of water. I would try to see how you can get in contact with a Vet in your area, whether they can come to you or you take Copper to them if he doesn't improve in the next 24 hours. I hope this helps and I wish Copper the best!
