🐶 How Much Hydrogen Peroxide For Dog Who Ate Chocolate? [2022]


Can you use Hydrogen Peroxide on Dogs?

Hydrogen peroxide and its effects have been studied extensively in the last 100 years, in part because it has been used to treat everything from bacterial-related illnesses to cancers in humans.

Despite the huge amount of research, there are sti

Despite the huge amount of research, there are still so many questions about the therapeutic use of this compound. You’ll find conflicting information everywhere, and not that much of it related to dogs. So the answer to the question “Can you put hydrogen peroxide on dogs?” is not clear-cut. Yes, you can. But it’s not always the right thing to do.

Our research shows that there are certain controlled situations in which hydrogen peroxide can possibly be helpful for dogs. But you should always consult your vet when your pet is unwell and see what they prescribe. It’s not ideal for all situations in which humans often turn to hydrogen peroxide. Thus, it’s much better to use medications that are designed for the dog’s specific conditions.

Ultimately, we can’t recommend hydrogen peroxide for wound care with dogs, based on the evidence. If your dog eats something poisonous, the careful use of hydrogen peroxide is recommended to get your dog to throw it back up. However, large items if made to regurgitate could cause your dog to choke! So it just isn’t that simple.

Also, hydrogen peroxide has been known to be effective in de-skunking dogs. Many home recipes for removing skunk odor include hydrogen peroxide. But are they entirely safe? Let’s take a look at these areas in more detail, to see where the problems arise.

If You Give Too Much, Contact Your Vet

It took me almost half a day's worth of research to find out what happens to a dog that ingests too much hydrogen peroxide. The best advice I found is to consult with your vet, for several reasons. Following are some:

  1. If your dog ingested a toxin and hasn't vomited, your dog needs a stronger vomiting medication, which only your vet carries. With this medication, your dog should be able to get rid of the actual toxin and the hydrogen peroxide on top of that. Remember: Timing is of the essence. You have only two hours to empty the contents of the stomach.
  2. If your dog ingested a higher dosage than the recommended amount and doesn't vomit, there are some risks of side effects. Veterinarians report that peroxide can cause stomach ulcers. According to veterinarian Dr. Michael Salkin,prevention of ulcerative gastritis can be instituted by giving the dog an H2 blocker antacid such as famotidine for dogs (better known as Pepcid AC). Owners should monitor for ulcers by watching for black stools, vomiting, and lethargy.

Dog Tear Stains And Hydrogen Peroxide

Some dogs produce excess tears, which stains the skin and hair surrounding the eyes.

This build-up looks awful and without proper grooming can result in infection or discomfort for your dog.

Regardless of its effectiveness, if you want to remove dog tear strains, hydrogen peroxide is not a safe option.

You should not use it near or around the eye area as it can cause severe damage.

No Amount of Chocolate Is Safe

Even a little bit of chocolate can make your dog ill.

Dark chocolates, baking chocolate, and dry cocoa powder are more dangerous than white or milk chocolate. But 1 ounce of milk chocolate per pound of body weight could still be deadly.

And unlike most cats, which don’t have a sweet tooth, dogs will eat almost anything. They also don’t know when they’re full, Wismer says. “They will eat as much as they can get ahold of. A 10-pound dog can easily eat a pound of chocolate.”

Alternatives to hydrogen peroxide for dogs

In the case that your dog has been poisoned or has ingested something toxic, you need to act quickly.

Your first move should be to call your vet.

Do not administer hydrogen peroxide without first consulting a professional. The alternative when it comes to poison control may be to have your dog’s stomach pumped.

How to Clean Dog Ears with Hydrogen Peroxide

The jury is still out on whether or not hydrogen peroxide is good for treating ear infections and for keeping ears clean. But, for the most part, vets advise going with a solution specially designed for cleaning ears, rather than using a homemade hydrogen peroxide ear cleaner. If your dog has an ear problem, you need to take him to the vet. It might not be caused by what you think, and they will have the best solutions.

Some vets will tell you that hydrogen peroxide’s antibacterial qualities can help remove bacteria and it is relatively safe. But because the solution quickly degrades to water after bubbling, it can also provide a moist environment inside the ear that allows bad bacteria to flourish.

Hydrogen peroxide may soften, but does not dissolve waxes and oils. Also, it does not kill infections as well as alcohol does. Additionally, using too much or using hydrogen peroxide inappropriately can cause irritation to a dog’s skin.

Hydrogen peroxide for dogs does not kill dog ear mites. Your best bet is to go to your vet and get medication specifically designed to treat your dog for ear mites. If it looks like your dog may have an infection, you should see a vet for advice on what to use, and to make sure the ear infection isn’t a sign of something more serious.

Can I put hydrogen peroxide in my dogs ear?

Dogs are prone to ear infections and yeast buildup, especially dogs that don’t have ears that stick up.  Hydrogen peroxide is a way to kill the bacteria in a dog’s ear without causing other bacteria growth.  This is because hydrogen peroxide dries extremely fast.  Many veterinarians will authorize the use of hydrogen peroxide to clean your dog’s ear as long as you make sure the hydrogen peroxide is able to dry.  If you don’t allow the hydrogen peroxide to dry, this can cause additional bacteria buildup.

To put hydrogen peroxide in your dogs ears, simply use cotton balls or gauze.

What to watch out for when putting hydrogen peroxide in my dogs ear

  • Do not use Q-Tips to clean your dogs ear.  The same risk applies to humans as you may penetrate the eardrum or ear canal.  Furthermore, Q-Tips push debris further into your dogs ear.
  • Monitor your dog’s ears for any type of irritation in the ear canal.  In certain cases, hydrogen peroxide may further irritation to your dog’s ear canal or eardrum.  Discontinue the use of hydrogen peroxide if your notice any irritation or discomfort in your dog.
  • Do not use hydrogen peroxide if your dog’s ears are red or inflamed.  There may be cuts, a ruptured eardrum, or other types of infections that your vet may want to examine.

Use Caution When Administering Hydrogen Peroxide to a Dog

It is essential that you consult a veterinarian before giving your dog hydrogen peroxide. There are many cases when it can cause more damage and even be fatal.

Do NOT administer hydrogen peroxide to dogs that . . .

  • have already vomited,
  • have trouble breathing,
  • are unconscious,
  • or are having seizures.

If you are unsure, play it safe and ask your vet or contact the ASPCA poison control number at 888-426-4435 (a $65 consultation fee applies).They should give you directions.

White Vinegar Solution

To make your own white vinegar solution, mix one part white vinegar to one part water. This solution seems to be beneficial for dogs that have chronic yeast and bacterial infections.


Supplies You’ll Need

Have all of your materials ready.  You should have:

  • Cleaning Solution (such as Hydrogen Peroxide, or one chosen from the list below),
  • Lots of Cotton Balls or Pads, and
  • A Dry Cloth.


Do not use Q-tips when cleaning your dog’s ears as it is too easy to insert them too deeply and injure his ears.  Your dog’s ear canal is L-shaped so you can’t clean too deeply anyway – which is helpful since you don’t want to.  You only want to clean the outer area of your dog’s ears, just like you would on yourself.


It’s always a good idea to start with a calm, relaxed dog.  Play a game of catch with him or take him for a walk to get out some of that abundant energy.  After that, take the time to pet him, rub his belly and try to make him as calm as possible. Make ear-cleaning time something to look forward to for your dog.


It’s a good idea to clean your dog’s ears outside or in the bathroom as things can get messy.  dogs aren’t always thrilled to have their ears cleaned and things might get spilled as they try to resist.


Put a small amount of your preferred cleaning solution on a cotton ball and start massaging your dog’s ear.  Start near the ear canal but never in it. You don’t want to go too deep as this could damage your dog’s ears.  Massage the solution gently into the skin allowing it to loosen dirt and wax. Your dog may want to shake his head. Go ahead and let him.  This will help to loosen the debris. Repeat this process using clean cotton balls as needed and continue from the inside of the ear to the outer edges.  Starting near the canal and moving away from it will pull the dirt away from the ear. If you start on the outer edges and move towards the canal you may push dirt and wax into your dog’s ears.  If your dog’s ears are particularly dirty or waxy then repeat the procedure until everything is clean. Afterward, wipe down his ears with a dry cloth.


When you have finished the process reward your dog with a treat so that he will know there is something to look forward to at the end of every ear cleaning.


Hydrogen peroxide is just one of the products you can use to clean your dog’s ears  Below I have listed a few of the cleaning solutions you can choose from. However, the one product you should never use is rubbing alcohol.  The inside of your dog’s ears is soft and sensitive. Rubbing alcohol can dry them out and cause rashes.


Conclusion: Is Hydrogen Peroxide Safe For Dogs?

Hydrogen peroxide is a common remedy for minor dog cuts, to clean dog ears, and induce vomiting within dogs.  Always consult your veterinarian if you’re unsure whether or not hydrogen peroxide is safe for your dog.

Lastly, never give hydrogen peroxide to cats as it is toxic.  Cats are extremely sensitive to hydrogen peroxide and can develop bleeding of their stomach from indigestion.  Many cats have died from hydrogen peroxide.
