My puppy is vomiting and has watery poop. Should I go to the ER vet?

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | unneutered | 4 months and 19 days old | 40 lbs

My 6 month old puppy has been vomiting periodically since last night. He has been pooping normally (in terms of color) but it has ranged from soft to water-like. I have an appointment with my regular vet tomorrow morning at 9:30 (they didn't have anything earlier) but I was wondering if I should take him to the emergency vet if this continues today, or if it should be safe to wait?

Poor Martin! I'm sorry to hear that he's sick. Vomiting can be caused by lots of different things. Some, like a mild upset stomach or eating something that didn't agree with him, are quite minor. Other possible causes are more serious, such as an intestinal obstruction, pancreatitis, ingestion of something toxic, or even parvo if Martin isn't fully vaccinated. To help determine how urgent the problem is, I usually judge this based on how the dog is acting otherwise. If Martin is still active and playful, interested in food and treats, and not having any other issues, then I would not consider this to be an emergency - in that case, you could opt to withhold food for the rest of the day today to give his stomach a chance to settle, then offer a small bland meal of plain boiled chicken and white rice this evening. Then, you can take him to your vet appointment tomorrow morning as planned. On the other hand, if he's acting depressed or lethargic, or isn't wanting to eat anything, I would be more concerned that something more serious may be wrong. In that case, it would be better to take him to an emergency vet today rather than waiting until tomorrow.
