What is Inducing Vomiting?

Inducing vomiting in your dog should only be undertaken either on the advice of a veterinarian or by a veterinarian, as there are medical conditions that make this unadvisable. Inducing vomiting in a dog is an emergency treatment used to expel a toxic or harmful substance from your dog's gastrointestinal tract, before it can be absorbed or cause damage. It must be undertaken shortly after ingestion, before the substance has passed through the stomach, to be effective.

In an emergency, your veterinarian may recommend you induce vomiting in your dog prior to transporting your dog to the veterinarian when time is critical. In these cases, only induce vomiting as instructed by your veterinarian. Certain poisons or existing medical conditions can be aggravated by this treatment, so it is important that your consult your veterinarian first. If possible, it is preferable to get veterinary treatment as it will be more effective and your pet can be closely monitored by your veterinarian in cases when poisoning has occurred.

Inducing Vomiting Procedure in Dogs

Induction of vomiting as a treatment to remove a toxic or harmful substance from your dog's gastrointestinal tract needs to be conducted within two to four hours of ingestion of the substance if it is going to be effective.

If your dog has ingested a harmful substance, contact your veterinarian to determine if you need to induce vomiting at home prior to visiting the vet or whether to transport your pet immediately to the vet for treatment. This decision will be based on how long it will take to get to the vet, whether the substance ingested and its toxicity can be identified or requires veterinary diagnosis, and the toxicity or potential damage of the substance ingested. 

If your veterinarian recommends you induce vomiting, the most common method recommended is to administer 3% hydrogen peroxide, by mouth (orally). The usual dosage is 1 teaspoon per 10 pounds of your pet’s weight. It can be administered by a syringe, turkey baster or eye dropper if available. This method usually results in your dog vomiting within 10 to 15 minutes, if it going to be effective. If possible, giving your dog a small meal prior to administering the hydrogen peroxide may help in the treatments effectiveness. If it does not work, it can be repeated once more. If a second attempt is unsuccessful, transport your dog to the veterinarian immediately. Regardless of whether your attempts at inducing vomiting in your dog are successful, your dog should be subsequently treated at veterinarian as vomiting only removes 40-60% of the ingested substance and further treatment of an ingested toxic substance may be required by your veterinarian. If you are unsure what substance your dog has ingested, take a sample of vomit with you to the veterinarian for analysis.

If vomiting is induced at your vet, he or she will administer an emetic that can be more effective than hydrogen peroxide and administer other follow up treatments.

For dogs, your veterinarian will administer apomorphine hydrochloride to induce vomiting. This medication may be administered orally, intravenously, or subcutaneously. It may be administered in a tablet placed under the eyelid (conjunctival sac) which dissolves and is absorbed; it is not as effective when administered intramuscularly. Vomiting usually occurs within 5-10 minutes. If administered using a tablet in the conjunctival (eyelid) membranes, excess dosage not absorbed can be removed when vomiting starts therefore avoiding administering more medication than is necessary. If it is not effective, additional dose are not useful.

Additional treatment with activated charcoal or other medication to prevent absorption of toxins may also be administered by your veterinarian and supportive care provided as necessary.

Efficacy of Inducing Vomiting in Dogs

Inducing vomiting will help minimize the effects of ingestion of a toxic or harmful substance. For the treatment to be useful it must be administered within 2-4 hours of ingestion. Antiemetics only remove about 40 to 60 perent of the stomach's contents, therefore while this is a useful emergency intervention to reduce the effect of a harmful substance being injested, further intervention by a veterinarian will be required. If conditions exist that preclude inducing vomiting, gastric lavage may be another treatment option.

Inducing Vomiting Recovery in Dogs

Recovery from induced vomiting will depend on what substance was induced, its toxicity level, timing of intervention, and how successful the treatment was. 

Apomorphine can cause central nervous system side effects such as excitement or depression. Dehydration can result if vomiting is prolonged. Your dog may require supportive treatment during recovery for central nervous system (CNS) symptoms, dehydration, or organ damage caused by toxicity. A special diet may be recommended by your veterinarian to provide organ support and restore electrolyte balance to your dog. You should monitor your dog for any concerning symptoms and report them to your veterinarian.

Cost of Inducing Vomiting in Dogs

Treatment for inducing vomiting in your dog can vary widely. Depending on your location, inducing vomiting in your dog can range in cost from $300 to $500. Additional costs associated with treatment of ingestion, e.g. activated charcoal, medications, hospitalization and supportive therapy can range up to $5,000, depending on the severity of your pet’s condition and treatments required.

Dog Inducing Vomiting Considerations

Treatment is only effective shortly after ingestion, usually within 2 hours. CNS stimulation or depression is a side effect of apomorphine and dehydration from vomiting is a risk. Both of these side effects can receive supportive treatment from your veterinarian.

Side effects of peroxide are rare but can include peroxide-induced brain inflammation. 

Animals that are at an increased danger of aspiration have an increased associated risk with emesis treatment of aspiration pneumonia. Dogs with laryngeal paralysis, megaesophagus, upper airway disease, and brachycephalic syndrome may be at increased risk for aspiration during vomiting and treatment with an alternative therapy such as gastric lavage may be considered.

If your dog is already showing symptoms of toxicity that include central nervous system symptoms, they are at an increased risk for aspiration, and as absorption of toxins has already occurred emesis may not be particularly effective.

Be sure to provide your veterinarian with information regarding any medications or conditions your dog has so they can determine the appropriateness of this treatment.

Inducing Vomiting Prevention in Dogs

Dogs are curious creatures. Removing toxic and harmful substances from your dog's environment so they are not apt to sample them or accidentally ingest them will prevent accidental poisonings or ingestions, and eliminate the need to induce vomiting in your dog. Be sure to identify all house and garden plants and check to see if they are toxic to your dog. Many common household and garden plant are not safe for dogs. Avoid giving human food to your dog unless you have checked whether they are appropriate for dogs. Many human foods such as grapes, chocolate, and citrus fruits are toxic to dogs. Remove small choking hazards from your dog's environment and keep all toxic substances such as household cleaners inaccessible to your pets. These precautions will also make your home safer for visitors with children or other pets.

I was cutting some loose threads off some of my clothes and thought I threw away all the cut stings until I noticed my dog chewing on a ball of a long gathered string of thread across the room. Before I could grab it out, she ran off and swallowed it. I went head and tried to use a little bit (a little less then a actual tea spoon) of table salt (I currently don’t have any hydrogen peroxide) to get her the throw it up, but was without luck. This all happened before I went to feed her so she doesn’t have any recent meal in her stomach, so should I feed her and then try again in about 15 minutes or just see if it will come out naturally. I know she’s eaten string in the past since she’s had (and destroyed) multiple rope toys, but I’m worried that because this time since it’s thread, it could cause an issue.

ingested gum with xylitol

My dog got into a pack of Orbit gum while I was helping my mom and cleaning the kitchen. Took 40 minutes max and when I came back to check on him I found only a few bits of the package on the floor. Mom told me it was an almost full pack so I knew this was bad. The nearest vet was closed (being after 10pm) and the closest open was over an hour away. I checked the dosage of hydrogen peroxide and induced him to vomit. I found bits of the gum in it when I cleaned it up. He vomited again about 15 min after the first time. No gum that I could see. Hes eaten a little bit and drank some water. He seems a little lethargic but I am keeping him up past his bedtime in order to watch him. No noticeable symptoms as of 2 hours since he first vomited.
What actions do I take now?

You should visit the nearest Veterinarian regardless of distance, xylitol is an artificial sugar which causes an increase in insulin production which leads to hypoglycemia (low blood glucose); if Mykah is showing signs of lethargy you should try to put some honey or karo syrup on the gums to help balance the blood glucose levels but without know exactly how much was consumed it is difficult to give any at home recommendation. You could also call the Pet Poison Helpline for further assistance as they will be able to discuss Mykah’s current condition with you.

Hello, I made my pittie vomit by using hydrogen peroxide and was successful. She ingested a rat bait block. I believe after an hour of us enducing vomiting 3-4 times that she is okay. However I want to be able to make sure there was no toxicity. She just ate and drank water. Is acting fine and there’s no CNS symptoms or depression. I don’t have the funds to take her to a pet ER. What should I do?

It sounds like you suspect that Penny ingested bromethalin rather than an anticoagulant rodenticide; if she consumed bromethalin you should administer of repeated doses of activated charcoal every eight hours up until 48 hours after ingestion since bromethalin undergoes enterohepatic recirculation. If an anticoagulant rodenticide was consumed then you should ensure that Penny receives vitamin K.

My dog had ingested raisins and so we took him to the emergency vet to be induced for vomiting. He ate the raisins between 7 P.M. and 10 P.M. and he was at the vet at 11:30 P.M. He threw up multiple times yet during the night drank a lot of water and went out to urinate three times. He didn't really get any sleep and is very lethargic today. He isn't eating and is lying down most of the time. Is this normal? Should we take him back to the emergency vet?

Dr. Callum Turner, DVM
Dr. Callum Turner, DVM
3317 Recommendations
It is normal for a dog to drink a lot of water after vomiting and it is also good for a dog to urinate frequently after eating raisins; being a bit sluggish after vomiting multiple times can be expected due to some abdominal pain. After the consumption of raisins it is important to keep an eye on kidney values (blood test) to keep a look out for kidney failure is a long-term problem after eating raisins.

My dog ate half a cup of chocolate covered coffee beans. I took her to the vet within 10minutes from the inccident and she's been given hydrogen peroxide and activated charcoal after she vomited a large amount of the chocolate and the coffee beans. When we got home she ran to her water bowl and had the whole thing. Minutes later she vomited a large amount of black water with some more coffee beans. She's been running back to her water bowl every minute and desperately hitting it with her paw for more water. Every time she get's any water in she can't hold it down and vomits black liquid. It's been 3 hours since we've been home and she puked 6 times. Is this normal?!

Thank you for your email. Palie should return to your veterinarian, especially since she still seems to be vomiting coffee beans and charcoal. Sometimes, when we induce vomiting, the dog might need a medication to stop vomiting. Since she is unable to keep water down, and is still vomiting black liquid, she should be seen again today. She may need supportive care if she did absorb any of the coffee beans, and she may need medication to settle her stomach. I hope that she is okay.

Inducing vomiting is most effective within an hour or two of ingestion, after this it is an unnecessary process to put an animal through; although a dog may vomit it may not bring all material up. If Kodiak is otherwise OK, I would feed small regular portions of bland food and monitor for any signs of pain or discomfort; if you are not seeing an improvement in the frequency of vomiting or have any concerns visit your Veterinarian.

Hi there, my 10 week old boxer puppy ate 3 baclofen tablets this morning. We took him to the vets immediately and he gave him an injection to induce vomiting and it kicked in and he did throw up after a few minutes. He was very tired and slept for a few hours after receiving this. 8 hours on he has stopped vomiting but is very wobbly on his feet and is pacing around from place to place whining and crying wich makes me feel awful for his situation. He has had a small amount of food and water but it's the crying and wining I'm worried about. Could he be in any pain? We took him to the vets within minutes of him swallowing these pills so is the after effects of the jab he's maybe freaking out to? Thank you in advance.

Dr. Michele King, DVM
Dr. Michele King, DVM
1607 Recommendations
If Cooper vomited up the tablets immediately after eating them, the chances are good that there aren't any residual effects from the medications. The drug that we give to induce vomiting in dogs commonly is a type of morphine, and can have strange effects for a day or two. If he is eating, drinking, not continuing to vomit, and otherwise doing well, you should be okay to monitor him, and know that he is not in pain, but is metabolizing that drug from his system. If he continues to do that for more than 12 hours, it would be best to have him rechecked to make sure that he is okay.

If Murray vomited up the grapes, it is a good sign; the effects of the hydrogen peroxide may still cause him to vomit for an hour or so after administration. You should keep an eye on him and offer water after an hour or so in small quantities; monitor him in the meantime and visit your Veterinarian if you have any concerns. If you feel that not all of the grapes were vomited up, visit your Veterinarian immediately. Regards Dr Callum Turner DVM

After inducing vomiting a dog may continue to vomiting for a few hours, rarely do they just vomit once; keep an eye on Harris for the time being and try withholding food and water until he has been an hour or two without vomiting, give him water and if he keeps that down give him small meals to see how he goes.

Dry heaving, honking, malaise.

My 12lb chihuahua terrier mix, Wyatt, ate nearly a full bar of dark chocolate (70%). I ran him to the ER Vet within the 3-4 hour range. They induced vomiting. They did subcutaneous fluids and sent him home. He slept most of the night, ate scrambled eggs in the am and seemed ok but in discomfort and fatigue. Then he started dry heaving and honking like a goose being tortured--sometimes for 5 minutes straight but then a break of 10 minutes. We went back to the vet and they gave him an anti-nausea med and an antacid. He is still violently dry heaving and looks miserable. Do I go back to the vet?? What do I tell them?

Thank you for your email. He may need continued supportive care. If he is still nauseous, he may need IV fluids and IV medications to help him through this. It would be best to take him back, yes, and let them know that he is still dry heaving, nauseous, and not feeling well. They can assess him and advise you on the best treatment for him.

You wouldn’t believe what I’ve pulled out (and seen pulled out) of different dogs stomachs; socks, bras, garter belt, certain types of marital aids etc… alongside other things like dish cloths and other strange things. Anyway, good thinking on inducing vomiting and getting the underwear out; Cinch’s stomach will be a bit sore after vomiting but should start drinking water after an hour or so, if not try to syringe a little into his mouth so some may at least be lapped up. Food wise, try a little wet food (you can mix a little water in too to help hydration); if you see no improvement after six hours visit your Veterinarian. Regards Dr Callum Turner DVM

You cannot buy Vitamin K OTC, it is a prescription medication, and it would be a very good idea to have him seen by a veterinarian to be examined. There are different types of mouse poison, and some affect clotting, while some affect the brain. He may need Vitamin K since it was up to four hours that he ate the block, or he may need other therapy, depending on the type of poison. It would be best to take the box with you so that they know what they are treating, and sooner would be better than later, as small amounts of mouse poison can cause problems, and even though you did induce vomiting, he may have absorbed some toxin.
