We have crabgrass growing in the back yard, where our dog runs. Even though we have a fence, she likes to get out, so I have to leash her sometimes. I want to put down a Scotts brand crabgrass preventer. Is it safe for the dog? if not what lawn product would be safe yet effective?.
As a dog owner trying to maintain a healthy lawn you may wonder if crabgrass preventer products are safe to use around your furry friend. Crabgrass and other weedy grasses can quickly invade and ruin an otherwise pristine lawn. But are the chemicals in popular preventer formulas like Scotts Halts safe for dogs who roam play, and lie on the grass? Let’s take a closer look.
How Crabgrass Preventers Work
Pre-emergent crabgrass preventers utilize synthetic chemicals that stop crabgrass and other annual weeds from germinating and developing. The active ingredients vary by brand but commonly include:
- Dithiopyr
- Prodiamine
- Pendimethalin
- Oryzalin
These chemicals inhibit root and shoot growth in newly sprouted weed seeds. When applied before crabgrass emerges in early spring, they provide season-long control.
Most crabgrass preventers are sprayed or broadcast over the entire lawn. The chemicals remain active in the soil for 2-4 months. As they break down, they lose effectiveness in preventing germination.
Are Crabgrass Preventers Toxic to Dogs?
Most lawn care experts agree that modern crabgrass preventers pose little risk to dogs when applied according to the label directions. The low concentration of active ingredients is not especially toxic to canines.
That said, all dog owners should exercise caution when using any lawn chemical. Accidental ingestion or skin exposure can cause irritation drooling, vomiting and in rare cases, neurological issues.
According to veterinarian Dr. Kara, common signs of poisoning include:
- Pawing at the mouth
- Difficulty swallowing
- Vomiting
- Diarrhea
- Dilated pupils
- Seizures
She notes that small dogs are at higher risk than larger breeds. Puppies and elderly dogs also tend to be more sensitive.
To be safe, it’s best to follow all label precautions when applying crabgrass treatment. Also take steps to minimize your dog’s exposure.
Tips for Using Crabgrass Preventer With Dogs
Here are some best practices for safely using crabgrass preventer when you have dogs:
-
Read the label thoroughly and follow all instructions. Never use more chemical than directed.
-
Choose pet-safe application times when your dog will be indoors. Avoid treating the lawn when dogs are present.
-
Prevent access until the product dries completely, usually 24-48 hours.
-
Dilute granular products with sand for safer application. Never allow dogs in the area during application.
-
Water the lawn lightly after application to dilute any residual chemical.
-
Pick up dog toys and bowls beforehand so they don’t become contaminated.
-
Keep dogs off treated areas for as long as possible, ideally until after the first mowing.
-
Use signs and barriers if needed to keep dogs away from application zones.
-
Bathe dogs immediately if they access a recently treated area.
-
Consult your vet if you suspect your dog has ingested or touched crabgrass preventer.
With proper precautions, most healthy adult dogs will not experience issues from preventer chemicals. But their long-term health impact is still debated. Limiting exposure is wise, especially for vulnerable pups.
Alternatives to Chemical Crabgrass Prevention
If you wish to avoid synthetic chemicals entirely, several alternative crabgrass deterrents exist:
Corn Gluten Meal – A natural herbicide made from corn, it prevents root development in emerging plants. Must be applied in early spring before germination. May take 2-3 seasons to work. Safe for dogs once watered in.
Vinegar – High concentrations (over 20%) of household vinegar can suppress crabgrass and are non-toxic. Results are marginal and multiple applications are needed.
Soil Solarization – Covering lawn areas with clear plastic during hot months “bakes” and kills crabgrass seeds in top layers of soil. Completely safe for dogs.
Preventive Mowing – Mowing to 2-3 inches all season encourages grass to outcompete crabgrass. Doesn’t kill existing plants but prevents spread.
Improved Drainage – Crabgrass thrives in compacted, moist soil. Aerating and amending soil to drain better creates unfavorable conditions.
Overseeding – Seeding thin lawns with turf-type grasses in fall bolsters density, leaving no room for crabgrass the following year.
With some creativity and extra effort, it’s possible to prevent crabgrass naturally. But results may not match what chemical options provide.
The Bottom Line
When applied per label guidelines, most crabgrass preventing chemicals present minimal risk to canine health. But it’s smart to minimize exposure whenever possible. Natural alternatives also exist for dog owners wishing to avoid chemicals altogether.
The best approach is integrated weed prevention that uses cultural practices, mechanical removal, and selective herbicide use when necessary. Your lawn will thrive and your dog can roam freely with a balanced, dog-friendly crabgrass control plan.
Re: Lawn product, safe for pets?
Dont intend to be negative but. crabgrass is a tough cookie. Even though I’ve had professional lawn care for decades, it comes back every year, mostly along my driveway and sidewalk. The roots get down and deep – however, in your doggy area probably no obstructions. Instead of sprays, the best way to get rid of dandelions without using chemicals is to buy a hand tool that pulls them out by the roots. Time consuming – yes.

Are pre-emergent herbicides safe for dogs?
The same recommendations go for most pre-emergent herbicides used to prevent crabgrass, however one natural ingredient that forms the base of organic herbicides is safe for your dogs. Pre-emergent herbicides that are pendimethalin-based are effective at preventing the invasion of crabgrass.
Are weed killers safe for pets?
Ugly weeds and grasses can muscle into yards and gardens, but for those who have pets, it’s risky to use weed killers made with harsh chemicals. Pets can pick up toxins through their paws and skin, or eat plants that absorb them. It’s possible to choose a pet-safe weed killer instead to protect furry family members while eliminating the invaders.
Are pre-emergent herbicides safe for crabgrass?
Pre-emergent herbicides that are pendimethalin-based are effective at preventing the invasion of crabgrass. According to the Environmental Protection Agency, the toxicity rating for this chemical is low. It rates as being in the third out of four categories for toxicity, where the first is the most dangerous.
Can Prodiamine kill crabgrass?
Prodiamine-based herbicides are also effective at preventing crabgrass. According to Refuse to Use Chem Lawn, prodiamine is a possible carcinogen and can lead to pulmonary fibrosis after long-time exposure. Although the effects on dogs are not stated, the chemical can be fatal to fish and invertebrates.
Are pet-safe weed killers effective?
Tell them which weed killer your pet encountered, and have the label or original container handy. Q. Are pet-safe weed killers as effective as traditional weed killers? Some are, but it depends on what you’re targeting. Some require repeat applications and take longer to work.
