1. Preheat your oven to 350°F and line a baking sheet with parchment paper—fishy treats love to stick without it.
2. Drain sardines thoroughly and mash with a fork until mostly broken down but still textured—your dog will start getting excited from the oceanic aroma.
3. Mix in cooked brown rice until evenly distributed, then gradually add oat flour until a workable dough forms.
4. Crack in the egg and mix until everything binds together without being sticky—add more oat flour if too wet.
5. Roll out on a floured surface to 1/4 inch thickness and cut into shapes or squares (ocean-fresh flavor matters more than appearance).
6. Place on prepared baking sheet and bake for 20-25 minutes until crispy and golden brown throughout.
7. Let cool completely before treating your pup—these need to be fully set for proper crunch and safety!

Notes:

• Always use sardines in water, never oil or salt-packed varieties
• Drain sardines thoroughly to prevent sticky dough
• Biscuits should sound hollow when tapped and feel crisp when done

Storage Tips:

• Store at room temperature for 1 week in airtight containers
• Refrigerate for up to 2 weeks for longer freshness
• Freeze for up to 2 months (they thaw perfectly)
• Keep in dry location to maintain crispness

What Makes This Recipe Special:

Whole sardines provide concentrated EPA and DHA omega-3 fatty acids that support coat health, brain function, and heart wellness. Combined with fiber-rich brown rice, these biscuits offer complete nutrition that dogs can’t get from synthetic supplements.

Mix It Up (Dog-Safe Variations):

Salmon Version: Substitute sardines with canned salmon for different omega-3 profile

Training Size: Cut into tiny squares perfect for reward-based training sessions

Coastal Blend: Add a pinch of dog-safe seaweed for extra ocean minerals
