Most homeowners understand the importance of keeping a beautiful, weed-free garden or yard, but what if you also have dogs? It’s lovely to have a weed-free yard or garden, but many weed killers on the market are loaded with dangerous chemicals.

Most harmful products including salt, arsenite, borax, or arsenic are no longer available, but certain weed killers, such as Roundup, may contain inactive substances that can cause burns, rashes, blisters, diarrhoea, vomiting, or death in dogs.

The bottom line is that chemical-laden weed killers may cause an allergic reaction or result in your dog’s death, but there are organic, pet-friendly weed killer alternatives. Remember that many of these formulae are non-selective, which means they’ll harm your lawn as well.

We decided to investigate and test the finest pet-safe weed killers because finding a weed killer that works while also being safe for your dogs can be difficult. We selected over a dozen products and tested them at home. We then reduced it down to six top choices.

How We Tested The Best Pet Safe Weed Killers

Many weed killers include dangerous chemicals that can harm your dog.
In regions where vegetation needs to be cleaned, non-selective weed killers are commonly utilised. These formulae are safe because they contain salt and vinegar, but if you spray them all over your grass, it will die.
We looked into all of the pet-safe formulations on the market to see what we could do to get rid of weeds without harming our dogs.

The ingredients were the first item we looked at. Although not all weed killers specify all of the chemicals, we discovered that vinegar was frequently indicated as the acetic acid and that a concentration of 10% to 30% had the best results.

Another important component is salt, a saline solution, or even “real” ocean water. Salt is an excellent ground-clearing element since it prevents vegetation from developing in the region for a long period.

We also checked to see if the weed pesticides contained glyphosate. This pesticide has been related to cancer in dogs, according to several studies.

Another no-no is iron, which can cause cardiac, metabolic, and gastrointestinal problems.
Then we looked at who the product kills. We found that the most effective pet-safe weed pesticides are non-selective. They destroy anything they come into contact with, but they do it swiftly and effectively, and once the formula has dried, pets and children can return to the area.
We looked into the frequency of application and, of course, the product’s safety for your dogs. We identified the best six pet-safe weed killers, as well as five runner-ups, based on our study. Continue reading to find out why we chose the products we did.

Primary ingredient: 20% acetic acid
Brand: Green Gobbler

  • Certified organic
  • Fit for residential use

You can’t go wrong with Green Gobbler and its certified organic formula if you have dogs at home. The main ingredient is vinegar, but the 20 per cent concentration makes it far more potent than culinary vinegar, which is only 5 per cent concentrated.

The extremely acidic mixture can be sprayed directly onto your weeds from the bottle. It immediately goes to work and destroys both weeds and grass.

It’s suitable for usage in residential, commercial, and agricultural environments. It’s also the ideal all-purpose weed killer for environmentally aware pet owners who need to get rid of weeds in the yard quickly.

The primary issue we had with this product was its lack of clarity when it came to other ingredients. Although Green Gobbler claims that the mixture is glyphosate-free and biodegradable, no more information regarding the components is provided.

We discovered throughout our testing that weeds will grow back, and we had to reapply to keep them at bay, so keep your expectations in check.

Green Gobbler is the ideal compromise between keeping your dog safe and having a solution that is efficient against weeds in general.

Is Glyphosate Harmful To Dogs?

Glyphosate is the most frequently used herbicide in the world because it is so effective, but it has been linked to cancer. As a result, we believe it is equally detrimental to dogs, especially if they come into touch with it frequently.
Glyphosate is “possibly carcinogenic to humans,” according to the World Health Organization. It is safe to use, according to the EPA, as long as it is used exactly as directed on the label.

How Can I Kill Weeds If I Have A Dog At Home?

Either a vinegar-based or a salt-based solution is your best bet. If you’re going to use vinegar, make sure to buy a solution that’s between 10% and 30% strength. Compare this to the 5% vinegar you have in your kitchen cabinet.
Mixing a salt-based solution with some water and spraying liberally all over your weeds, avoiding grass and plants you don’t want to destroy, is the ideal approach to apply it.

In conclusion

Many weed killers are not safe for pets. Even if you’re careful to avoid spraying herbicides near your pet’s favourite spot to pee, accidents can happen. And if you have a curious pet, they may end up licking or eating something they shouldn’t.

Our list of the best pet-safe weed killers that you can trust to keep your furry friends safe and healthy will help you tackle your weed problems whilst protecting your loved ones.

There are a number of weed killers on the market that are pet safe. If you’re looking for an environmentally friendly and pet-safe option, look for herbicides that contain pelargonic acid or fatty acids as the main ingredient.
