Dogster_Is Dawn Dish Soap Safe for Dogs

Whether romping in the mud or rolling in the smelliest item that they can find, dogs always seem to find a way to get smelly and dirty. If you find yourself out of doggy shampoo with a pup in desperate need of a bath, you might wonder if the solution lies in your kitchen. Dawn dish soap is one of the most popular dishwashing liquids, so is Dawn dish soap safe for dogs? It is safe to use on your dog, but it is not recommended for regular bathing.

In this article, we go over why Dawn dish soap can be effective for cleaning your dog and why it’s not a good idea to use it frequently.

Dawn Dish Soap Is Safe for Dogs But Is It Effective?

Most of us are probably aware that Dawn dish soap is commonly used to clean wildlife caught in oil spills. Gentle enough to clean even baby animals, it is also strong enough to handle the worst messes your dog will encounter. Sometimes, veterinarians may use or recommend Dawn dish soap to bathe your dog if they get a toxic substance on their skin or coat, especially one with an oil or petroleum base.

Our Favorite Products

Selecting the right shampoo and conditioner makes the world of a difference when grooming your pup. Our favorite products are the duo by Hepper. The Oatmeal Pet Shampoo is formulated with aloe and oatmeal to soothe skin and hydrate the coat. The Pet Conditioner works at eliminating tangles and taming frizz and static. Both products are pH-balanced and formulated with pet-friendly ingredients, free of harsh soaps, chemicals, and dyes. Give this duo a try to heal and nourish your dog's coat, and leave them with an irresistible just-left-the-spa cucumber and aloe scent.

At Dogster, we’ve admired Hepper for many years and decided to take a controlling ownership interest so that we could benefit from the outstanding designs of this cool pet company!

Will Dawn Dish Soap Kill Fleas?

Dawn dish soap is regularly suggested online as a flea-killing alternative to more expensive parasite preventatives. But does it work? The answer is yes but there's a catch.

Bathing your dog in Dawn should kill any adult fleas on their body. Fleas can usually float in water, but the chemical reaction caused by Dawn soap interferes with the flea's exoskeleton, causing them to sink and drown. Veterinarians in animal shelters often use it to kill fleas on puppies and kittens too young for other flea control medications.

However, Dawn provides no lingering protection or repellant against further flea infestations. You can kill all the fleas on your dog, and they could immediately become infested again by the fleas in their environment. Dawn is also ineffective against flea eggs or immature fleas. Complete flea control requires breaking the life cycle of the parasite by destroying all these stages. We don’t recommend relying on washing with Dawn soap to treat your dog's flea problem.

For more effective flea control, veterinarians recommend using prescription flea and tick prevention year-round once your dog is old enough. Many different products are available, and your vet can help you choose the one that will work best for your dog.

Why Dawn Shouldn’t Be Your Regular Dog Shampoo

So, Dawn is safe for your dog and will get them clean, but it won’t do a good job of dealing with fleas. So, why shouldn’t you use Dawn dish soap to regularly bathe your dog?

The problem with Dawn being so effective at removing oil is that it works on all kinds of oils, even the natural ones that your dog produces. Your dog relies on those natural oils to keep their skin and coat healthy and moisturized. Removing them by bathing with Dawn (or similar soaps) will dry out your dog's skin, possibly leaving it itchy, flaky, and uncomfortable.

If your dog already has sensitive or irritated skin, bathing with Dawn could worsen the problem. If your dog scratches excessively, they could create open sores or develop an infection.

The best option for bathing your dog is a shampoo formulated for use on pets. If your dog has allergies or a skin condition, your vet may recommend specific shampoos. For routine bathing, however, your choices are endless!

Final Thoughts

Inexpensive and readily available, Dawn dish soap is tempting when it comes to choosing a bathing option for your dog. While technically Dawn dish soap is safe for dogs and not toxic, frequent use could dry out your dog's skin and hair and should be avoided. Every dog's grooming needs are different, so you must select a shampoo that not only keeps them clean but also won't cause problems for their skin in the process.
