Why is it dangerous to pets?
Blood meal and bone meal smell like food, so dogs eat them readily — and a large amount of blood meal can cause pancreatitis and severe gut upset.
Organophosphate and carbamate insecticides in combined “weed and feed” products block an enzyme that controls nerve signals, causing SLUD signs — salivation, lacrimation, urination, diarrhoea — and muscle twitching. Iron-containing fertilisers add iron poisoning.
Why speed matters
Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.
Symptoms of fertilizer poisoning
- Drooling, watery eyes, vomiting, diarrhoea
- Pinpoint pupils, muscle twitching, tremors
- Weakness, difficulty breathing, slow heart rate
- Abdominal pain, restlessness, pacing
- Bloody vomit or dark stools if iron-containing
What to do right now
- Call your vet or a poison line and read the product label — the active ingredient changes the treatment.
- Bring the bag; wash pellets off the fur and paws so grooming does not continue the exposure.
- Do not induce vomiting unless instructed.
- Store fertiliser in a sealed container, and keep pets off treated lawns until watering has soaked it in.
If your pet shows any of the signs above, go to the nearest emergency vet now and call ahead.
