Frequently Asked Questions
My dog just ate something that's giving them a bad stomach — what do I do right now?
That's scary, I get it. First, take a breath. If they've only vomited once or have soft stool, remove any more of the stuff they ate. Offer a little water. Watch for the next 2 hours. If they vomit again, go downhill, or have blood, head to the vet. Don't give any home remedies unless you've already checked with your vet.
How can I tell if my dog has a simple upset stomach vs something like pancreatitis?
Good question, because they look similar. Pancreatitis usually comes with a hunched back, reluctance to move, and repeated vomiting that doesn't stop. A simple upset often passes after one or two throw-ups, and your dog still wants to move around a bit. If in doubt, let the vet check.
My dog has had diarrhea for 2 days but is still eating — when should I worry?
Two days of diarrhea is already reaching the 'call your vet' zone, even if your dog seems okay. They can get dehydrated fast. If you see any blood, tiredness, or the diarrhea doesn't stop after a bland diet, definitely call. Puppies and seniors need attention sooner.
If I wait and see, could the vet bill be even higher?
Unfortunately, yes. A mild case that turns into dehydration or infection means more tests and fluids. Catching it early, even if you just call the vet, can save you money and your dog's comfort.
I'm terrified my dog might have a blockage — what are the signs beyond vomiting?
I hear you, that's a real fear. Blockages often show up with dry heaving, a painful belly (they may yelp when touched), no poop for 24+ hours, and they'll stop eating entirely. If you see any of those, don't wait — go to the emergency vet.
What can I do regularly to prevent my dog from getting an upset stomach?
Stick to a consistent diet, avoid table scraps (especially fatty ones), keep trash bins locked, and make sure they're up to date on deworming. Slow down fast eaters with a puzzle bowl.
