Having a weed-free yard is a summertime goal for many homeowners. Weeds can mar up an otherwise pristine patch of grass. Plus, they can take hold of the plants you want, depriving them of the water and valuable nutrients they need to grow.

The go-to method for removing weeds is using a weed killer. These products, also known as herbicides, target pest plants while leaving your healthy grass intact.

How Are Weed Killers Dangerous?

Dogs can't resist a good romp in the grass. They make direct contact with grass every single time they go outside. If your yard is doused in weed killer, your canine companion could experience a host of physical problems.

Direct skin contact is a significant issue. Your pup could absorb the chemicals in the grass through the paw pads.

Because dogs like to investigate through their sense of smell, they may even inadvertently inhale the chemicals! Every roll, sniff, and step presents a health hazard when traditional chemical-based weed killers are thrown into the mix.

The worst part of it all? The potential health risks aren't always apparent. In most cases, the health issues come later after continual exposure.

There's no way to know if weed killers are wreaking havoc on your dog's body until it's too late.

Potential Health Ramifications

Want to know how dangerous traditional week killers are?

According to studies conducted by the University of Maryland, weed killer chemicals are detectable in a dog's urine! If chemicals appear in the urine, it means that the dog absorbed them and attempted to process them through the kidney.

Clearly, this is not good for long-term health.To make matters worse, those studies showed that the chemicals appear for up to three days after the weed killers were applied!

Most assume that chemicals are absorbed into the soil after only a few hours. The University of Maryland studies show that's not the case. Dogs can still experience ill-effects after application.

The Issues

The health issues a dog can experience vary quite a bit based on the chemical and the amount they come into contact with.

The most immediate effect is vomiting and diarrhea. The chemicals interact negatively with the stomach, resulting in massive pain and gastrointestinal troubles.

Your canine may also suffer from symptoms of poisoning. They could go into shock, start shivering, or have difficulty breathing.

In the long-term, kidney failure is in the cards. The constant attempts of ridding the body of chemicals will take their toll, leading to eventual organ failure and death.

The Biggest Offenders

When it comes to what kinds of ingredients are in weed killers, the list is vast! However, there are three that scientists believe have the worst effects. These include Glyphosate, 2,4-D, and Sethoxydim.

Glyphosate is one of the most popular active ingredients. It's non-selective, so it kills everything! Some plants are resistant to its effects, but you will most often see this product being used around concrete environments.

2,4-D, also known as Trimec, uses hormones to control weed growth. This is the type that likes to cause immediate effects in dogs. When inhaled or ingested, canines can suffer from diarrhea, vomiting, and other unpleasant issues.

Sethoxydim usually targets grasses. While not as toxic as the other two herbicides, it still causes similar symptoms to poisoning.

How Do Pet-Friendly Weed Killers Work?

Pet-Friendly weed killers are still capable of killing plants. But, they go about the job very differently.

These products utilize safe, all-natural ingredients. Many are organic by nature, eliminating the inherent danger that chemicals present. Your dog still shouldn't consume large volumes of the stuff. But, your pup shouldn't experience any issues if they inhale, ingest, or roll around in it.

Most rely on drying or acidic agents. For example, salt, vinegar, essential oils, and citric acids are quite popular. Those ingredients can remove the waxy plant cuticle of the weed

while damaging cell walls. This eliminates the plant's ability to take in nutrients, depriving it of its energy and drying it out.

How to Use Pet-Friendly Weed Killers

Even with pet-safe herbicides, you need to exercise caution and apply the product safely.

The first thing you should do is read the instructions throughout. Concentrated products may require dilution. You should also pay attention to the characteristics of the product.

For example, some are selective, which means that they target a specific kind of plant. Others are non-selective and will kill everything like glyphosate! To successfully manage a weed problem, you need to understand what types of weeds you're dealing with.

Pre-emergent or Post-emergent?

Another thing to check is how the products attack the plant. Is it pre-emergent or post-emergent? Pre-emergent products treat weeds before they appear. They can seep into the soil to stop the germination process in its tracks.

Meanwhile, post-emergent weed killers deprive existing plants of nutrients, as we discussed earlier.

Once you familiarize yourself with the product, clear your yard. It's best to keep your dog out of the yard for at least 24 hours. Take them to a local dog park or go on a stroll around the block for exercise.

Avoid applying the product on rainy or windy days. You want your applications to matter, so pick a day with good weather. Apply the weed killer according to the instructions, and you should be able to tackle your weed problem without the use of harsh chemicals!


You don't have to choose between a weed-free yard and a safe yard. With one of these pet-friendly weed killers, you can have both!

These products use Mother Nature's own herbicides to eradicate invasive plants without the use of harsh chemicals. Your pooch can run and play without the risk of long-term health complications.
