|---|---|---|---|---|
| Yes | Moderate | Immediate to 2 hours | Common (popular houseplant) | Urgent |
The Toxic Principle
The dangerous compound in Pothos (Devil's Ivy) is Insoluble calcium oxalate crystals (raphides).
Pothos contains insoluble calcium oxalate crystals embedded in the plant tissue. When a dog chews the leaves, these needle-shaped crystals penetrate the oral mucosa, tongue, and throat, causing immediate pain, swelling, and irritation. Dogs are less likely than cats to chew plants but larger dogs may ingest significant amounts.
How Much Is Dangerous?
The risk depends on your dogs's weight and the amount ingested.
| Pet Weight | Dangerous Amount | Expected Severity |
|---|---|---|
| Small dog (under 20 lbs) | Even a small bite causes oral pain and drooling | Moderate |
| Medium dog (20-60 lbs) | Several bites cause vomiting and oral swelling | Moderate |
| Large dog (60+ lbs) | May tolerate small amounts with mild symptoms | Mild |
