Lawn and Garden Fertilizer: A Common Backyard Hazard

Fertilizer toxicity varies enormously depending on what's actually in the product, which is why checking the bag or bottle, if it's still around, is one of the more useful things you can do in this situation. Basic fertilizers with nitrogen, phosphorus, and potassium tend to cause mostly digestive upset if eaten in typical amounts. The bigger danger comes from combination products — fertilizers mixed with pesticides, herbicides, or "bone meal" style products that smell appealing to dogs and can also cause pancreatitis or, in some cases, intestinal blockages from the dense meal-based formulation clumping in the stomach.

Symptoms to watch for: vomiting, diarrhea, drooling, and abdominal discomfort. With combination products containing pesticides, additional symptoms like tremors or difficulty breathing are possible.

What to do right now: find the product packaging if at all possible — the specific ingredients matter far more here than with most other toxins, since "fertilizer" covers products with very different risk profiles. A basic lawn fertilizer and a combination bone-meal/pesticide product warrant very different levels of concern.

When it's an emergency: any combination product involving pesticides, or any significant amount of a bone-meal style fertilizer given the blockage risk on top of toxicity.
