Why is my puppy throwing up foam and coughing? Is it acid reflux?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | unneutered | 5 months old

My 5 month old puppy throws up white and yellow foam, coughs as if he were choking but wasn’t. Usually this happens at night and the vomiting early in the morning. I’m really worried. Is it due to not eating enough ?

This could very well be caused by acid reflux due to an empty stomach. Especially if Toby is otherwise acting normal and not vomiting up undigested food. I would try offering him a late night snack and ask your vet if an antacid dosage can be provided, considering his medical history. Best wishes with your puppy and I hope the vomiting resolves soon!
