Keeping Your Lawn Weed-Free and Dog-Safe: The 5 Best Pet-Friendly Weed Killers for Lawns

Dogs enjoy frolicking in yards and rolling around in grass. It’s what they do. Having a weed killer that is safe for pets is very important if you want to keep your lawn in great shape.

The chemicals used in most weed killers and lawn treatments can be bad for our pets. I know this from personal experience.

A few years ago, my spouse and I took a vacation to Maine that allowed pets. While our Cocker Spaniel was playing on the bed and breakfast’s lush, green lawn, he had an event. Our dog Brandy began vomiting and developed a prickly red rash across her stomach. When I called a pet poison helpline, they told me that she probably had chemical exposure and that I should take her to the vet. She received IV fluids, a bath, a blood panel, and ointment for her chemical burns. It turns out the property had used a chemical weed killer a few days before our arrival.

Since then, I’ve made it my mission to tell other pet owners about how dangerous some weed killers are for pets and why they should use pet-safe alternatives instead.

As a dog owner, keeping your lawn lush, green, and weed-free can be a challenge. You want your lawn to look its best, but you also need to make sure any weed killers you use are safe for your furry friends. The good news is there are several effective yet dog-safe weed killing options available both online and in stores.

In this article we’ll cover the top 5 pet-friendly weed killers recommended by lawn care experts and veterinarians. We’ll outline how each organic-based weed killer works to target weeds without endangering your pets. We’ll also provide tips on how to apply these dog-safe products for maximum results.

Understanding Dog-Safe Weed Killer Ingredients

The key to finding a dog-safe weed killer is looking for natural, non-toxic ingredients. Here are some of the most common organic ingredients found in pet-friendly weed killers:

  • Vinegar Higher concentrations of vinegar work to burn and dehydrate weed leaves Vinegar breaks down quickly and won’t leave lingering chemicals

  • Citric acid: Derived from citrus fruits, citric acid damages weed cell walls and foliage. It’s biodegradable and safe around pets.

  • Fatty acids: Naturally occurring fatty acids like pelargonic acid disrupt weed growth but won’t irritate skin or be toxic if ingested.

  • Iron HEDTA: This chelated iron supplement stresses and destroys weeds. Iron HEDTA has low toxicity levels for mammals.

  • Clove oil: The primary active ingredient in clove oil, eugenol, is an effective natural herbicide. Clove oil is safe for dogs at herbicide concentrations.

Applying Dog-Safe Weed Killers for Best Results

  • Spot treat weeds or do blanket applications when pets are not present. Keep dogs off treated areas until the solution has dried completely.

  • Target young, actively growing weeds for most effective results. Mature weeds may require repeat applications.

  • Spray weeds thoroughly, especially the leaves. Avoid runoff to keep pets away from excess product.

  • Reapply as needed for continued weed prevention and new growth. Most natural weed killers last 1-2 months.

  • Combine with manual weed pulling for severe infestations. Natural herbicides work best on smaller weed populations.

  • Avoid using near delicate plants and lawns unless labeled as safe. Vinegar-based weed killers can potentially damage other plants.

Roundup and Pets: Is it Safe?

dog safe weed killer for lawns

Roundup is a popular weed killer and lawn treatment, but its main ingredient is isopropylamine salt of glyphosate. Monsanto, the manufacturer of Roundup began selling the product in 1974. In 2015, the World Health Organization determined that glyphosate is “probably carcinogenic to humans. ”.

In 2019, a California couple won a $2 billion dollar lawsuit after they developed cancer linked to the use of Roundup weed killer. Although the judge cut the lawsuit to $86.7 million, the settlement was upheld.

Pets often lick their feet or fur while they are relaxing around the house. Dogs like to roll around on grass, and many cats go for walks on a leash where their paws touch grassy lawns. Any non-pet-friendly weed killers they encounter outside can be ingested into their bloodstream.

According to the National Pesticide Information Center, pets that come in contact with wet glyphosate products may drool, have gastric upset, lose their appetites, or become sleepy—none of which are noted on the Roundup labeling or website.

Should you decide to use Roundup to kill weeds, keep your dog away from the area that has been treated. If you have any concerns, talk to your vet.
