My dog had diarrhea, now no poop and threw up. When to see vet?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Female | spayed | 2 years and 1 month old | 25 lbs

We have a 2 yr old beagle mix (25 lbs), and she had sudden diarrhea on Wed night after passing normal stools during the day. She had 4-5 liquid stools Wed night into Thurs morning. We withheld food on Thuruntil the evening, when we started chicken and white rice meals. She has been a little lower energy, but overall seems okay, except that she hasn't had a bowel movement since her diarrhea on Thurs morning.. She ate some grass and threw up saliva this afternoon. When should we go to the vet?

I'm sorry Maeby has been having problems with diarrhea for a couple of days! You did the right thing by withholding food and trying the bland diet of chicken and rice. It is normal to see a period where a dog doesn't pass any feces after having diarrhea for a few days, and I wouldn't be too worried about that just yet. It is a little concerning that she threw up this afternoon, and I would continue the bland diet for another couple of days before adding back in her normal diet. I would go to the vet if the vomiting continues, she becomes very lethargic, the diarrhea returns, she stops eating, she stops drinking, she starts vomiting water, and/or she has pooped in another 24 hours. Best of luck, I hope this helps!
