## Root Cause

Peanut butter can contain aflatoxins from Aspergillus mold, which cause severe liver damage and failure in dogs, even in small amounts.

## Workarounds

1. **Use a commercial dog-safe peanut butter that is tested for aflatoxins, such as 'Pupford' or 'Dog for Dog' brands. Check batch lot numbers on FDA recall lists before feeding. Example: 'Choose a brand that explicitly states aflatoxin testing on label.'** (82% success)

   ```
2. **Feed dogs a small amount of plain, unsalted, roasted almond butter instead (but avoid xylitol). Almonds have lower aflatoxin risk but still monitor. Example: 'Limit to 1 teaspoon per 10 lbs body weight, and inspect for any mold.'** (75% success)

## Dead Ends

- **** — Recommending only brand-name peanut butter like Skippy or Jif ignores that aflatoxin can appear in any batch regardless of brand, and these brands still contain added sugars and salts harmful to dogs. (35% fail)
- **** — Suggesting making homemade peanut butter from raw peanuts is dangerous because raw peanuts may carry Salmonella and aflatoxin risk is not eliminated by home grinding. (25% fail)
