11 Best Pet Safe Weed Killers 2024 + Complete Guide & FAQs

Weed killers can be potent, noxious chemicals that are harmful to more than the vegetation they’ve been designed to destroy.

This includes our children – whom we do occasionally have some moderate control over.

However, when it comes to our beloved family pets, they can often wander into areas of the garden unsupervised and eat or lick anything they like the look of until their heart’s content.

Which is potentially deadly if you’ve just covered the place with a toxic chemical.

With that in mind, I’ve put together a review of the best pet safe weed killers on the market, to keep your four-legged-friends out of harm’s way.

A buyer’s guide and FAQ section will follow the reviews, so read on to discover the best non-toxic weed killing options for your property.

Red Dragon VT

Check availability, reviews and price

As this is an article about weed killers, I thought I’d include a couple of other options of the non-compound/liquid variety.

This is a propane vapor torch for use with a tank of gas to eradicate weeds directly by burning them away. No chemicals of any kind are required, and you can spot target each unwanted boom until it’s burnt to a crisp.

It comes with a 10 ft U.L. listed LP gas hose, adjustable needle valve, and a spark lighter. Of course, you still need to purchase the propane tank, which should be 20 lbs or higher.

The kit has received CSA certification for use in the U.S. and Canada and is pet safe (providing you don’t point it at your pet that is).


  • Chemical free.
  • Target the weed directly.
  • No regulator required.
  • Multiple uses.


  • Gas tank sold separately.
  • Expensive.
  • Overkill for smaller properties.


Thinking outside the box when it comes to weed killing, this is a decent alternative, a pet-friendly option that might be well worth your consideration. You’d probably have a lot of fun blasting weeds away, too.

Fiskars 3 Claw Garden Weeder

Fiskars 3 Claw Garden Weeder

Check availability, reviews and price

While there are myriads of weed-removal tools on the market, I’ve gone for this one from trusted Finnish brand, Fiskars – just to get you started and offer another pet-friendly weed killing solution.

It’s perfect for anyone who wants to remove weeds the old-fashioned way, yet takes a lot of the back-breaking work out of the job. The long handle prevents sore knees and having to stoop and bend, while the three serrated, stainless-steel claws firmly grab weeds and roots for permanent removal.

Simply position over the target weed, stamp it down on the foot platform, and then let the claws do the work as you pull the weed right out by the root.

There’s a good possibility that this will make weeding your garden fun.


  • No harsh herbicides in sight.
  • Easy-to-use.
  • Eco-friendly all round.


  • Can only be used on weeds with a central tap root.
  • Claw adjustment is often required.


A terrific option for bringing weeds up right at the root. Even if you still end up using a pet-friendly herbicide on larger areas, this is an awesome tool to have in your gardener’s armory.

Failing that, why not try one of these commercial weed eaters as an effective (albeit temporary) weed removal method.

How to Choose the Best Pet-Friendly Weed Killer

Below you’ll find some tips and advice for selecting the right weed killer for your needs – and for the needs of your pet. An FAQ section will follow in case anything has been missed.

Check the Ingredients

If you’re looking for a pet-safe weed killer, then the first thing you need to be mindful of is the ingredients.

Toxic and harmful herbicides contain chemicals and compounds like glyphosate, alachlor, and dacthal to name but three.

While they might be the best weed killers for Bermuda grass and other intrusive and aggressive plants, some of these chemicals are either banned or in the process of being banned in many parts of the world.

So, if you want to make sure the product you’re buying is pet and human safe – do your homework on the ingredients – and not just the active ingredients, as some can hide a nasty little surprise if you’re not careful.

Look for products that are 100% organic and contain natural ingredients.

The downside is that they are generally not as effective as stronger chemicals, but they’re considerably less deadly to anyone and anything that might come into contact with them.

Approved to be Pet Safe

Apart from doing your own homework when it comes to seeking out pet-safe formulas, probably the surest way to know is to check if a product has actually been approved to be pet-friendly.

If it’s been passed by OMRI (Organic Materials Review Institute) or the EPA (Environmental Protection Agency), there’s a very good chance it’s safe to use if you have furry friends around.

Although it seems obvious, if a product has a picture of a cat or dog on the label, then that’s usually a sure sign it’s a pet-safe formula.

And any product that’s been given the nod from a veterinarian or other pet-friendly association is also a safe bet for use around your family – furry or otherwise.

When in doubt, you could always ask your vet for additional advice.

Is it Necessary?

Before purchasing any kind of weed killer, ask yourself if it’s really necessary. Is the problem so bad that it can’t be resolved with a bit of elbow grease?

There are plenty of other options for weed removal (I’ve included a couple of examples in the review) that are much more pet-friendly than even pet-friendly weed killing products.

It’s highly advisable to avoid any kind of herbicide use if you can help it, as a few weeds here and there isn’t going to do much harm – but a bad chemical reaction certainly might.

A Word of Caution

On that note, it’s worth mentioning that although these products are advertised as pet safe and pet-friendly – that’s only if they’re used correctly and as advised.

These products can still be an irritant if they get on skin or fur, into the eyes, or somehow digested – like when Buddy enjoys eating the dandelions.

While they’re nowhere near as lethal as some chemicals, they can still cause a seriously upset stomach, so precautions need to be taken.

Always keep pets and children indoors while applying any kind of weed killer – and give the product time to dry and be absorbed before unleashing the little beasts. And your pets.

The same goes for other chemicals you might use, like stump killers, etc.

What’s the best weed killer that’s safe for pets?

I’m afraid to answer that question it really is a case of trial and error.

To help you find the product that will give you the best results, I’ve put together this review.

However, in order to find which one really works for you and to answer this question, you might need to try a few formulas before settling on one that is successful.

Read the comments from people who have tried the product already and it will help you make your choice.

There’s no right or wrong answer here as what works for some people might not work for others.

What are the possible dangers to pets when using a weed killer?

Check out the excellent and informative video below to learn more about the dangers of using chemicals around our pets.

How do you apply a weed killer safely around your children or pets?

As I mentioned above, pet-friendly or pet safe weed killers are still harmful if used incorrectly and not according to the manufacturer’s instructions.

I would still take similar precautions you would for using chemical herbicides – just to be on the safe side.

Keep your pets and children indoors as you’re applying the formula, and leave it for at least an hour before allowing them out to play.

Make sure to wear long-sleeved clothing and pants, close-toed shoes and hand protection.

For this type of product, use a pair of some good quality landscaping gloves for the job.

Is spraying weed killer on the lawn harmful to children or pets who play on it?

It depends on the weed killer. If you’re spraying dangerously noxious chemicals, then it will most certainly be harmful to children and pets.

Is Roundup safe for pets?

No. Use with extreme caution. Remember, its active ingredient is currently in the process of getting banned in many places around the world.

What are some weed-killing alternatives that are safe for pets?

Cat and dog cuddling in grass

I included a couple of other options in the review for you to consider as alternatives to using any kind of liquid or granule formula.

Burning the weeds with a propane vapor torch will focus solely on the targeted weed, and you run no risk of pets getting sick even if they do eat or lick the end results.

You could always put together your own homemade weed killer using any number of recipes on the internet – but they can be hit-and-miss when it comes to success.

Perhaps the best pet-friendly weed killing alternative is to simply remove them by hand. Use some good, old-fashioned grafting and you won’t have to worry about anything hazardous being around your loved ones.

It’s also good for you from an exercise point of view.

How long after spraying herbicides is it safe for pets?

Even with pet-safe formulas, I would advise erring on the side of caution if you can and give it a window of 24 hours.


Our beloved four-legged-friends are worth so much more to us than the necessity to remove a few pesky weeds, so really consider them and the environment before opting for a chemical herbicide.

The best pet safe weed killer is just to do it by hand – but if you really have to, the products in this review are a great start – and certainly a better alternative to harsh, toxic chemicals.

Good luck in choosing the right one for you – let me know what works and what doesn’t.

Happy weed killing – and much love to all the pets out there!
