1. Preheat oven to 350°F and line square baking dish with parchment paper (makes removal so much easier).
2. Mash sardines with fork until chunky but broken down—your kitchen will smell like fishy heaven to dogs.
3. Add cooled quinoa, pumpkin puree, mashed blueberries, and ground oats, mixing until Amber starts drooling.
4. Press mixture firmly into prepared dish—use some muscle to pack it down evenly.
5. Bake 20-25 minutes until set and lightly golden (start checking at 20 minutes).
6. Cool completely before cutting into squares—patience is key here, even though those puppy eyes are irresistible.

Notes:

• Always drain sardines thoroughly to prevent soggy squares
• Make sure quinoa is completely cooled before mixing
• Press mixture firmly for squares that hold together perfectly
• Amber prefers these cut into bite-sized pieces he can savor

Storage Tips:

• Store covered in refrigerator for up to five days
• Freeze in single-serving portions for up to two months
• Don’t leave these out—fish treats spoil quickly without refrigeration
• Thaw frozen squares overnight in the fridge for best texture

What Makes This Recipe Special:

Sardines provide the highest concentration of omega-3 fatty acids available in dog treats, supporting everything from coat shine to joint health. Combined with complete protein from quinoa and antioxidants from blueberries, these squares deliver veterinarian-level nutrition in a format dogs think is pure indulgence.

Mix It Up (Dog-Safe Variations):

Joint Support Special: Add tiny pinch of turmeric for natural anti-inflammatory benefits (perfect for 8-year-old pups like Amber)

Training Size: Cut into pea-sized cubes for mess-free training rewards that fit in any treat pouch

Iron Boost: Substitute finely chopped spinach for blueberries for dogs who need extra iron support
