Is Fertilizer Dangerous for Dogs?

Fertilizer is usually low risk around dogs unless large quantities are ingested. Most cases of ingestion result in gastrointestinal distress, including vomiting or diarrhea. 

However, the risk increases substantially with small breeds and puppies, as their little bodies can only handle so much.

fertilizers for dog owners

With that in mind, whether they’re pet-friendly or not, all fertilizers can be dangerous if stored incorrectly.

Furthermore, like other lawn care products, many fertilizers contain added substances that can be incredibly dangerous for dogs, risking your dog’s health and safety if he even runs across a freshly treated area. 

So, only select pet-friendly fertilizers to prevent injury or illness and follow the manufacturer’s directions closely.

Dog-Safe Products Still Warrant Caution

Your pup can be sickened by eating any fertilizer, dog-friendly or not, especially if he eats a significant amount. Since manufacturers don’t disclose every ingredient for us to investigate, we can’t guarantee that ANY of today’s picks will be completely safe, despite bearing a pet-friendly label. 

It’s always best to keep your canine clear of the area as your lawn absorbs fertilizer and to store products far out of your dog’s (and children’s) reach, preferably in a locking cabinet.

Pet-Care Pro Tip: Want to protect your garden from your doggo?

As any pet-loving gardener knows, while we love them, dogs can wreak havoc on plants. Sometimes, it’s best to keep them away from the space entirely, preventing them from damaging your plant babies and, better yet, from coming into contact with fertilizer.

What Chemicals Are in Fertilizer?

What Chemicals Are in Fertilizer?

The biggest concern surrounding fertilizers is the chemicals used within them, as manufacturers aren’t always super transparent with listing every ingredient in a detailed list like dog food must. As pet parents, this is worrying, even for products that claim to be pet friendly.

The active ingredients of most fertilizers are:

  • Nitrogen: This growth-promoting nutrient is the most important active ingredient to look for in fertilizer as it’s the most needed by plants to help them grow stronger.
  • Phosphorus: This ingredient is responsible for helping plants convert nutrients for new growth but shouldn’t be applied excessively or before heavy rain.
  • Potassium: Generally used in smaller amounts than nitrogen and phosphorus, potassium strengthens a plant’s root system and helps protect it from disease. 

These active ingredients (often listed as NPK, which refers to the element symbols) are often broken down on the packaging into ratios such as “5-10-10,” meaning the fertilizer is 5% nitrogen, 10% phosphorus, and 10% potassium. 

Having the right balance of nutrients for your specific application is essential, as too much of a given element can damage your lawn or plants, known as “burning.”

These active ingredients are often derived from natural sources like plants or manure, but they can also be synthetic. For dog-safe applications, seeking a natural option is recommended.

Some fertilizers also include other nutrients to aid in plant growth. While they’re not as widely used as the top three picks, they’re still helpful in certain applications.

Trace minerals featured in fertilizer include:

  • Calcium
  • Sulfur
  • Iron 
  • Zinc

Always read up on what nutrients the type of plant or grass you’re treating needs, as some are finicky and can burn easily.

Fertilizers may also contain fillers to make the granules for application. These ingredients aren’t the star of the show, but they’re worthy of scrutiny, as they may potentially contain harmful chemicals to your pup.

Common filler ingredients in fertilizer include:

  • Sawdust
  • Ground corn cobs
  • Peat moss
  • Dirt
  • Sphagnum 

These aren’t things we’d feed a dog, but they may be harmless, provided they’re not chemically treated to repel bugs or large enough to be eaten in excess and cause an obstruction.  

How Do You Pick a Dog-Safe Fertilizer?

Selecting a dog-safe fertilizer starts with picking one labeled as safe for pets. From there, you can drill down into other criteria.

As a general rule, consider the following when shopping for the right dog-safe fertilizer:

  • Skip those containing substances known to be dangerous to dogs. Cocoa bean mulch is a prime example of a known toxic ingredient in fertilizer. Others feature large grains of corn cobs as fillers that can make your dog ill if consumed.
  • Avoid unnecessary additives. If your lawn doesn’t need insecticide or herbicide, skip its inclusion. It’s not worth risking your pup’s safety.
  • Be critical of organic options. While more natural than other options, organic doesn’t always necessarily mean safe for use around dogs. Some organic fertilizers have ingredients that make the product more appealing to your pup to sniff or even eat, such as manure. 
  • Aim for transparency. Not every fertilizer manufacturer lists every ingredient, but some do a great job of letting you know what is and isn’t in their product, making your choice easier. Give them business over those who list the bare minimum. 

Sometimes there’s an ingredient you’re not sure’s safe around sniffers, and other times your dog’s sensitive to things other pups aren’t. When in doubt, ask your vet. 

Using Fertilizer Safely Around Dogs

Just because a product is marked as dog safe, that doesn’t mean you can use it any way you see fit. Always follow the manufacturer’s instructions to keep you and your canine safe. That said, all fertilizers have basic safety measures to take.

With any fertilizer, remember to

  • Keep your dog off the lawn for roughly 48 hours. Yes, some products claim to be safe right after application, but it’s always best to be as safe as possible, particularly if you have a pup known to scarf down things he shouldn’t, such as new granules in the grass.
  • Store products safely. Even dog-friendly fertilizer can be dangerous if ingested, particularly if your pup eats a large amount or is small, young, or medically fragile. Always store fertilizer and other lawn care products out of reach, preferably in a locking cabinet, as some ingredients have scents that entice dogs to chow down.
  • Clean up the area. If spreading granules, be sure they’re evenly distributed and do not collect around walkways, patios, or lawn ruts. Check the space after application and remove or redistribute any wayward fertilizer. 
  • Wash your hands thoroughly after handling fertilizer and other yard care products. You don’t want to expose yourself or your dog to hidden chemicals. You also don’t want to accidentally spread them around your house as you go about your day.
  • Double-check the product’s safety data sheet: Many fertilizers and yard care products have a safety data sheet provided by the manufacturer so you can check for risks, such as skin or eye irritation. If something bothers humans, it’s going to bother pets, too, so heed the warnings.
  • Watch your dog: After applying fertilizer and waiting the designated time, monitor your dog in the area to see if he’s sniffing, pawing, or nibbling at the grass, potentially consuming remnants. Don’t allow him to ingest granules. Also, watch him for signs of a problem, like skin irritation around the paws, vomiting, or diarrhea. If noted, contact your vet.
