📊 Nutrition Notes
Sardines are one of the most nutrient-dense foods available — rich in omega-3 fatty acids, calcium (from the soft bones), vitamin D, B12, and selenium. They're low on the food chain so have minimal mercury. Potato starch is easily digestible and grain-free.
💡 Tips
- Tinned sardines with bones are fine — the bones are soft and full of calcium
- Roll as thin as possible for maximum crispiness
- The fish smell is strong but dogs absolutely love it
- These are like gourmet fish crackers for your pup
