My old dog is throwing up and won't eat. When should I see a vet?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | unneutered | 13 years and 7 months old | 12 lbs

Dog started vomiting yesterday and has so far vomitted four times over the course of the day into the night. He hasn't eaten in 24 hours. Has only drank a little water. Does not have worms and has all current shots. Age 14. Shitzu terrior mix. Vomit was bit of undigested food at first then just chunks now more runny. No blood or blackness. Stool was only a bit loose today. No blood in it either. Wondering if he ate a bit of table food that made him sick? What's normal & when to go to vet?

occasional vomiting is common but if it persists longer than 72hours, he refuses food for more than 48hours or refuses to drink/vomits water back p after drinking at any stage he should be seen by your vet as soon as possible. Blood and urine tests should be considered to rule out medical cases if there has been recent weight loss or increasing thirst
