Why Fertilizer is dangerous
Many fertilizers are tasty to dogs; some contain iron or organic meals that cause GI upset or worse.
Bone meal, blood meal, and other organic meals
The counterintuitive leaders in fertilizer raids: to a dog, organic meals read as dinner rather than groundskeeping, so the ingestion tends to be large. GI upset is the common outcome, and the quantity eaten is what earns the vet call.
Iron-added and combination products
Risk rises with the iron content on the label, and lawn products that bundle fertilizer with insecticide or weed killer carry that second ingredient's risk on top. Keep bags labeled and intact: the label is what your vet will ask about.
Treated lawns
The open bag is the emergency; the lawn is the caution. Keep dogs off freshly treated grass, follow the product label's own re-entry directions, and then let normal yard life resume.
Signs to watch for
Vomiting, diarrhea, drooling, belly pain
