Pet safe weed killers, though beneficial, are not free from drawbacks.
Susceptibility to water erosion, the difficulty of application, as well as potential weed resistance are just some of the negatives you may encounter.
Most of the products below must be used in clear weather to minimize water erosion. Pets must also be kept away during the application, especially if the weed killer in question needs time to dry.
How They Work
These products work by inhibiting a plant’s ability to sustain itself in some way.
Most of the vinegar-based weed killers dry out plants by forcing them to lose moisture content. Corn gluten-based products prevent weed roots from taking hold during germination.
Also, some grasses are better than others for dogs, so be sure to learn about them when trying to cultivate the perfect lawn for your pet.

If you’re in the market for an organic weed killer, Energen Carolina has you covered.
The company’s Energen Carolina Vinegar Weed Killer is a noteworthy inclusion in this list. As the name suggests, this herbicide makes use of vinegar as its primary ingredient, with devastating consequences for weeds. Unwanted grasses and weeds will begin wilting away within minutes of contact.
Usually, chemicals with such effectiveness come with the downside of being highly toxic…but not this time. Energen Carolina Vinegar Weed Killer does not contain glyphosate or any other chemicals that may be harmful to people or animals, making it a viable (and organic) alternative to traditional weed killers.
You can opt for a standard bottle or a spray bottle, with either choice coming with a pre-mixed solution that does not require further dilution. All you need to do is go out on a dry day and spray problem areas. Applying the product on rainy days will reduce its effectiveness due to chemical run-off.
Kids and pets can freely play in the yard again once the weed killer has dried, and you can rest easy in the knowledge that they are safe.
Some bird species may be affected by the smell of vinegar though, so bird-lovers might want to steer clear.

How Do Pet-Safe Weed Killers Work?
Pet safe weed killers work by eliminating weeds or preventing their growth altogether.
Of course, traditional weed killers operate in the same way but the difference is that, with the pet-friendly options, you don’t get any toxic ingredients. As you can see from the list above, substances like glyphosate, sulfates, fluorine, or even bleach are hardly used in eco-friendly weed killers due to their potential impact on ecosystems, animals, and even people.
Instead, these weed killers make use of organic ingredients like vinegar and corn gluten to curb the threat of weeds. Vinegar, for example, speeds up water loss from weeds, causing them to wilt and die out. Quite a few of the products listed above are based on a vinegar formula and they all work similarly.
Weed “killers” based on corn gluten formulas play a preventative role in weed management. Corn gluten, if applied before weeds germinate, will stifle their roots before they take hold. This effectively “chokes” the weeds out before they can reach maturity and cause problems.
How Do Conventional Weed Killers with Glyphosate (Roundup) Work?
Conventional (or non-pet-friendly) weed killers are made up of a wide variety of chemical substances that stop growing weeds in their tracks.
One of these chemical substances is glyphosate, an organophosphorus compound that goes by many different names in the market. Zero, No Grow, and, of course, Round-up are just a few glyphosate-based weed killers available today. Although it is made for killing weeds, glyphosate will kill all other plant life it comes into contact with, so be warned.
Typically, these weed killers are sprayed onto targeted plants. The glyphosate then infiltrates the leaves and moves down to the roots, where it inhibits nutrient absorption. When this happens, the plant will not be able to respire or produce food to sustain itself, which causes it to wilt up and die.
Dangers of Conventional Chemical Weed Killers
While conventional weed killers are still used in the U.S. and beyond, new research continues to uncover a few problems with some of the key ingredients.
Glyphosate, in particular, has been found to be especially problematic. According to the U.S. Department of Agriculture, the popular chemical has been linked to worrying health problems in humans and animals.
Human cancer incidences in areas where crops treated with glyphosate are consumed have gone up considerably over the last few decades. Non-Hodgkin lymphoma is one of the major cancers that has been on the rise during that time, with focused studies in Argentina pointing to a clear link between glyphosate and tumors.
The findings from animal studies have been even worse.
Lab rats exposed to the chemical through feed have been found to develop tumors and severe DNA damage. Additionally, bio-mechanisms that are meant to naturally prevent this damage may also be negatively affected.
Glyphosate weed killers have also been linked to birth defects such as hollow bones and other skeletal deformities in humans. Studies on rats seemingly prove this link, with pregnant females that were exposed to the chemical giving birth to litters of developmentally stunted young. Pups in these litters would frequently die, and those that managed to survive were found to be sterile.
Some rats might not even give birth. Spontaneous miscarriages were also a common finding among pregnant rats who were healthy before exposure to glyphosate.
Additionally, male rat pups whose mothers were exposed to glyphosate were found to exhibit “abnormal sexual behavior”, severely reduced sperm counts, and premature or delayed puberty.
Other problems found in lab rats include enlarged testes, deformed vertebra, and severely stunted endocrine function. Also, rats exposed to glyphosate were found to be three times as likely to die as rats that were not exposed to the herbicide.
All of these study findings are definitely not pleasant reading for any pet owners, as most or all of the above effects can just as easily affect your dog, cat, and any other animals in your yard. Heck, some of these conventional herbicides may even harm kids!
How to Properly Use Pet Safe Weed Killers to Minimize Risk to Your Dog
There are various ways to make use of pet-friendly weed killers without harming your dog.
Most of the products listed here have very simple instructions for their application. Due to their chemical composition, most of these products pose no threat to most healthy animals.
However, if your pets have underlying conditions, or if you just want to play it extra safe, you can close them off indoors or in your garage while you apply the herbicide and wait for it to dry.
You can also dilute liquid herbicides further to reduce their concentrations. Be careful with this though, as you could seriously weaken your product’s ability to kill weeds.
DIY Pet-Safe Ways to Kill Weeds
Some people may feel that the best way to kill weeds without harming their pets is to create their own homemade weed killer. The following is a brief list of household items that you can use to deal with weeds in your garden.
As we discussed earlier in the article, vinegar is an awesome substitute for conventional herbicides. A few sprays of the substance will cause weeds to lose their moisture content via osmosis. Dogs and cats are not affected by vinegar at all, but birds may not like the smell of high concentrations.
Applying salt is a good way of making the soil underneath your weeds hostile to plant life. The excess sodium is absorbed by plant roots and dries up the weeds from the inside.
Using boiling water is arguably the easiest way to kill weeds, especially if they are concentrated in one spot. Weeds will die upon contact and you won’t have to worry about any nasty chemicals harming your pets.
With public consciousness regarding the dangers of traditional weed killers on the rise, many home and pet owners are turning to more organic solutions to rid themselves of their weed problems. Products like Just for Pets, and others in this article are simply the safest option for our animal pals.
