Why Dogs Vomit: How to Treat Puppy Vomiting At Home

by | Dec 5, 2019 | Dog Training & Care | 28 comments

A vomiting dog or puppy vomiting can be very dangerous for your pet, and while we don’t like to talk about it, pet vomit is a fact of life. A dog throwing up bile–that yellow foamy stuff–often happens on an empty stomach. Dogs vomit more readily than almost all other animals. (The cats just started snickering . . . ) When we brought a new puppy into our house, we became even more alert to the issue.

Water Binging Vomit

Bravo-Dawg used to vomit due to high-energy play immediately after eating–or gulping down buckets of water. We learned to keep him calm for at least a half-hour after meals, and to interrupt his water-binging antics.

With tiny puppies, it’s even more important for them to get a health evaluation more quickly since they can get even sicker quicker than the bigger or adult dogs. Puppy vomiting is even more serious when accompanied by diarrhea. That can cause pet dehydration that kills. It’s important to understand why dogs vomit, and whether or not to treat puppy vomiting at home.

Puppy Vomiting

There are many reasons why your dog vomits, from innocuous to potentially deadly. Vomiting is the forcible expulsion of the stomach’s contents up the dog’s throat and out of the mouth. However, you should be aware that vomiting is different than regurgitation.

Dog Regurgitation

Regurgitation is a passive process without strong muscle contractions. Regurgitation can occur minutes to hours after your pet eats his food, and the expelled material is undigested and may even be tube-shaped like the throat. Cats fed cold canned food may “whoops” it back up very quickly, or dogs that gulp and swallow too fast may regurgitate their food. Mom canids in the wild do this when they return from hunting, in order to feed their pups.

Occasional regurgitation isn’t a cause for concern unless it interferes with nutrition and what you feed your pet. Chronic regurgitation typically is seen in a young puppy. In these cases, regurgitation can cause slow growth and may be due to a physical problem like megaesophagus.

In cases of poisoning or swallowing dangerous objects, you may need to induce vomiting. Learning how to make puppies vomit can save his life.

Dog & Puppy Vomiting: Why They Do It

When the “vomit center” of the brain is stimulated, the puppy begins to salivate and swallow repeatedly. Your puppy may seek attention or look anxious. Then, the stomach and abdominal muscles forcibly and repeatedly contract, while at the same time the esophagus relaxes. The puppy extends her neck, opens her mouth and makes a strained gagging sound as the stomach empties.

Vomiting should never be considered normal. Most cases of adult dog vomiting result from gastric irritation due to swallowed grass, eating inedible objects, spoiled or rich food (raiding the garbage, table scraps) or simply eating too much too fast. You can prevent puppies from eating the wrong thing with these puppy proofing tips. Dogs and puppies also may vomit from motion sickness during car rides.

Common Causes of Puppy Vomiting

The most common cause of vomiting in dogs is gluttony. Dogs that gorge their food tend to lose it just as quickly, particularly if they exercise shortly after finishing a meal. This type of vomiting isn’t particularly dangerous, but is annoying. And if they eat the wrong food, it can prove deadly.

Repeated vomiting, vomiting along with diarrhea, unproductive vomiting, vomiting not associated with eating, and/or the pooch acts like she feels bad before or after the event is a cause for alarm. Puppies with vomiting quickly develop dangerous dehydration. There are electrolyte replacement products to combat this, like Petralyte.

why dogs vomit

Vomiting can be a sign of canine distemper virus or canine parvovirus, which can be prevented by proper vaccinations. In deep-chested breeds, unproductive vomiting may be a sign of bloat. Bloat (gastric dilatation and/or volvulus) happens with the stomach swells and potentially twists without emptying and can kill dogs very quickly–big deep-chested dogs (German Shepherds like my Magic and big dogs like Bravo-Dawg) are most prone.

If the vomit contains blood or fecal material, if it lasts longer than 24 hours, or if other signs such as diarrhea accompany the vomiting, contact your veterinarian immediately. For some types of vomiting, home care may be all that’s needed.

Home Remedies for Dog & Puppy Vomiting

Vomiting that happens only once or twice isn’t a cause for concern as long as the puppy or dog acts normal before and after. But very young puppies and especially Toy-size breeds shouldn’t go without a meal for longer than about six to eight hours, though, so you’ll need vet help with tiny pups. These little guys also dehydrate very quickly which can complicate matters.

Vomiting may be a sign of serious illness, though. Anytime your pet vomits three or more times in a single day, or two or more days in a row, you should take her to the vet.

What about you? Have your puppies or dogs ever had a scary/dangerous bout of vomiting? Magic got REALLY sick one time with explosive diarrhea and vomiting and turns out he’d caught a “bug” from drinking pond water.

  1. Zoe Campos

    Thank you for telling me that vomiting may be a sign that my puppy is suffering from a more serious illness. My Japanese Spitz refused to eat and puked twice last night, but she looks fine now so I thought there will be no more problems. After reading your article, I’m convinced now that I should consult a veterinarian immediately.

  2. steph

    My puppy was throwing up and had diarrhea. We thought he was overwhelmed because we had a long ride from picking him up but he had Parvo virus. Call the vet, or the emergency vet and ask for advice. We brought him in on a Sunday and any later it would have been too late. At the very least, call! It’s free to ask for advice

    • Amy Shojai

      Steph, you are ABSOLUTELY RIGHT! Calling the veterinarian is the single most important thing you can do for your pet when s/he’s ill.

  3. Jean Stallworth

    my pit bull puppy is vomiting he is about 8weeks old a rescue from bad people in his life so I took him in but he eats everything mud grass sticks how do I keep him safe what may I give him to help him

    • Amy Shojai

      Until you can see the vet on Monday, I’d withhold solid food for now. A couple of spoonfuls of plain, nonflavor yogurt may help settle his tummy. For pups that eat everything, it’s important to supervise everything and try to give them “legal” chews (it’s hard, but worth it!). Good luck! And bless you for adopting this baby.

  4. Linda Tucker

    Thank you so much for sharing this advice on how to help your dog when it comes to vomiting. I had no idea that dogs eating really quickly could cause vomiting to occur; it sounds like I need to get my dog a “foraging bowl” to make sure that he doesn’t eat too fast. Since he is a deep-chested dog, I want to make sure that his chances of vomiting or getting bloat are as low as possible.

  5. Carol Bryant

    Such a good post, Amy. I know transitioning from having a senior dog to a puppy, I panicked at first with vomiting and realized that puppies don’t do well with mixing treats.

    • Amy Shojai

      Hi Carol, it really does make a difference between dogs, too. Some simply have a more “ify” tummy than others. My Magic has a cast iron gut…so when he vomits I take it much more seriously.

  6. Maureen

    Great information. My dog Rosa vomits a lot. I give her a Pepcid in the evening which has really helped her. She is highly allergic to things and has such a sensitive tummy.

  7. Jen Jelly

    I love the phrase “eat a grass, have a puke.” I don’t remember when I originally heard it but it always makes me giggle since occasional vomiting is pretty much the norm for us dog owners. Great information – especially considering that vomiting in puppies can be the sign of something serious.

    • Amy Shojai

      LOL! I’d not heard that before, but I’ll remember that saying. *snert*

  8. Jessica Rhae (@YDWWYW)

    Gretel ate some chocolate once and I tried the hydrogen peroxide thing but it didn’t work. It was the right concentration, and I gave her three doses all together, but still nothing. I am thinking of trying epicac next time but I heard that it can be dangerous because some dogs won’t stop vomiting after taking it. Hopefully, she will never get into poison again and it won’t be an issue.

    • Amy Shojai

      That’s so scary! I hope you don’t have that chocolate poison issue, either!

  9. Robin

    Very interesting. I don’t remember whether either of my dogs had vomiting problems. It has been a long time! It’s great to see that there are some simple ways to induce vomiting in a dog if they eat something they shouldn’t. I didn’t know they could use Pepto Bismol either.

    • Amy Shojai

      You do want to be careful about over-doing the Pepto, but it is safe now and then when used as directed by the vet.

  10. Jennifer

    A few years ago, our Beatrice was regurgitating several times a day. We tried several medications and even a surgery but nothing worked. It was so awful. After we changed to a different specialist, she was diagnosed with IBD. By feeding her 4 times a day instead of two times a day with a slow feeder bowl and with the use of medication, she stopped regurgitating. She’s been off medication for about 2 years and is continuing to do really well. It is so sad when our fur-babies are not feeling well and we don’t know so easily what is wrong or how to help.

    • Amy Shojai

      Jennifer, this is great information to share. Thank you! I hope it will be helpful to others who may have dogs suffering from this frustrating condition.

  11. Robbi Hess

    Thank you for this extremely helpful information. Neither of my dogs vomit with any regularity but it is great to have this checklist so if they do I will know whether it’s normal or something to worry about.

    • Amy Shojai

      Thanks for visiting the blog Robbi!

  12. well minded

    This is great information to have. My pups have only vomited rarely, thank goodness! Those feeders you mentioned are great and very effective. Several of the dogs I take care of use them.

    • Amy Shojai

      Which of the feeders do you like best?

    • Amy Shojai

      Magic has slowed down his munching as he’s aged, but wish I’d had a slow feeder when he was young.

  13. Val Silver

    Uggh! Teddy throws up grass and he gets car sick within 15 minutes of being in the car and keeps getting sick. I feel so bad for him. We just got him some high power medicine from the vet, hope it works for those unavoidable long trips.

    • Amy Shojai

      Hi Val, car sickness is so aggravating. Yes, the vet has good meds that can help. You can also try offering a natural nausea remedy—ginger. You can find ginger capsules at health food stores. Dogs under 16 pounds can safely take 250-milligrams or less of ginger, while puppies over 16 pounds can usually handle up to 500 milligrams of ginger. Some of the dog show folks tell me they just give their dog several ginger snap cookies—and eating cookies in the car can be a great positive association for the dog, too. Be aware that the cookies can stain light fur, though, if he munches and drools.

  14. amyshojai

    Hi Cathy, Magic does the same thing, if he fails to eat it makes him sick to his stomach. I also think it’s a ploy to get “treats” on to of his food to encourage him to get something on his tummy.

  15. Cathy Armato

    Great post, thanks for this information! My Husky vomits occasionally, and seems to be linked to NOT eating rather than eating. If we don’t feed her early enough in the morning once in awhile she will vomit up bile. We usually feed her a small amount right afterwards which seems to help. We try to stick to a solid feeding schedule but sometimes it isn’t possible.

Welcome Trinity-Kitty: New Kitten Baby Makes Three!

On Monday September 11, 2023, a tiny speck of a kitten made her presence known with very loud MEWS and a personality way bigger than anyone expected. Hungry, full of fleas, and the expected roundworms (and probably tapes because…fleas), her eyes and ears looked too big for her delicate wedge-shaped face.

Now, I get alerts about “found” kittens all the time, and sadly, can’t take any of them. This baby proved different in so many ways–only some of which I can share. While at the grocery picking up kitten food, my husband called and I explained my next stop at church—Trinity Lutheran—where I hoped to find a forever-home for the baby with a family who tragically lost a beloved kitty. And I told him if that didn’t work out, we likely had a third furry wonder for our home.

My friends at church, not yet ready to welcome a new pet, meant that the kitten came home with me. It seems that the Higher Being with whom all things are possible, made sure she found her way to us. He knew we needed her as much as she needed us.

How to Read Dog Poop: Normal Dog Poop to Dog Poop Problems

How to Read Dog Poop: Normal Dog Poop to Dog Poop Problems

Everyone who shares a home (and heart) with a dog at some point must deal with dog poop problems. Learning what’s normal, to yellow colored stool, or learning how serious blood in dog’s stool diarrhea may be helps get your dog help. While it may not be the most appealing topic, learning about your dog’s “creativity” offers important insight into his health.

Not only his food, but also your dog’s environment and emotional state, affects how his body works. Fear, anxiety, and stress can change a dog’s behavior, but also can disrupt digestion and cause enteritis. That in turn affects his poop.

Recognizing healthy elimination helps pet owners alert to abnormal eliminations. That way, when necessary, you can get your dog prompt medical help to diagnose and treat problems before they become worse.

Adopting “Other-Abled” and Less Adoptable Pets

September 19-25 is National Adopt A Less Adoptable Pet Week, founded by The organization encourages shelters and rescues to create special week-long events devoted to giving overlooked pets like those with disabilities a better chance at finding homes.

This struck a chord with me, especially after living with a tri-pawd dog when Bravo lost his leg. He didn’t act disabled, though. Have you ever adopted an other-abled pet or less adoptable pet?

What Is A Less Adoptable Pet

Why less adoptable? They’re the wrong breed or have special needs. Overlooked pets include deaf dogs or deaf cats, blind pets, or those missing a limb. Many folks prefer the ‘perfect’ cute puppy or kitten and don’t want a crippled pet, or just don’t like the color of the dog or cat. Of course, we know black dogs and cats, and those with only one eye, or three legs, still love us with all their furry hearts! Read on…

Why Do Cats Fight After Vet Visits? How to Stop Cat Bashing

Congratulations! Your hard work has paid off, and Kitty no longer fears the carrier and handles the car ride with almost no signs of fear, anxiety or stress. Kitty purrs and cheek-bonks the veterinary technicians, and barely notices the doctor’s exam through all the petting and tasty treats. But as soon as you get home, Kitty’s former feline friends snub him, or worse. Why do cats fight after vet visits? What’s up with all the cat bashing?

What A Pain! Understanding Pet Pain & What to Do When Pets Hurt

September is Animal Pain Awareness Month, so I wanted to share this vital information again. We know pain hurts, but pain in pets and treating pet pain when pets hurt confuses us. They can’t tell us they feel pain, or where it hurts. Not like humans.

Because I get to work at home, there are certain perks I enjoy–such as going barefoot to work. But one afternoon last fall I moved too fast and kicked the whey outta my big toe. This wasn’t just a stubbed toe, either—it lifted and peeled the nail back to the quick, bled everywhere and hurt like the devil! Yes, I said a few choice words as I hobbled down the stairs from my office (trying not to leave a bloody trail) to get bandage material. Ooooooh, that puppy throbbed and made me whimper and howl, let me tell you.
I understand how Magical-Dawg felt several years ago. After a run in the field playing fetch, he started shivering when he came inside. The ninety-degree weather argued that he was not chilled. I checked him head-to-tail, and found nothing wrong. But later in the week, he again started shivering, and even growled at me when I asked him to move—very uncharacteristic.

Finally, after several days and two vet visits, we figured out his problem. He’d torn a dewclaw back to the quick. it hadn’t come off, so the injury remained hidden. Seren-kitty had this happen once, too, when her claw caught on bedding as she leaped from the pillow. She hid. But Magic’s short temper, shivers, and hyper-alert behavior resulted from being in pain. Here’s what you need to know to help your pets.

Pet First Aid Medicine Chest: Home Remedies to Save Pet Lives

Do you have a pet 1st aid medicine chest for your dogs and cats? The audiobook version of my first aid book for pets includes some DIY home remedies for old pets. While your veterinarian diagnoses and prescribes for your pet’s health issues, pet first aid and minor problems may benefit from human medicines.

Home remedies for pets save $$ and pet lives because Fido and Sheba rarely tears a claw or eats something iffy during regular clinic hours. It’s helpful to know how to use your pantry supplies and human medicine chest to help your cat or dog. Some people prescriptions can be dangerous (especially for cats!) so it’s a good idea to have a handy list.

Pet Vacation Options: Boarding, Pet Sitters, Stay-Cation?

It’s DOG WALKER APPRECIATION DAY! And maybe you have a regular dog walker (your kid? a company?) that manages when you can’t walk your dog, or go on vacation. Good pet vacation plans depend on the individual pet and your special circumstances. When my mother became ill and then passed away, we need to find a pet boarding place for Shadow-Pup and Karma-Kat to stay. Does your dog love riding in the car, meeting new people at the boarding kennel, hide from pet sitters, or become hyper around strangers? Maybe you’d like to learn about traveling with your pet.

Perhaps Chance the cat enjoys riding in the car but your brother’s dog hates kitties, or Grandma is allergic. Are pets more comfortable at a kennel away from your nephew’s hair-pulling fingers? Or does your pet go on a hunger strike if boarded?

I can’t remember the last time that my husband and I had a vacation together, but I do remember how boarding my dog led to a broken arm (read on for that story!). Since that time, we make an effort to not be gone at the same time. There are times, though, when we must leave them behind, maybe not for vacation but other reasons. Here are some tips for pet vacation issues.
