A Cool, Omega-3 Rich Treat That Dogs Absolutely Love. If you’re looking for a dog treat that’s packed with nutritional benefits, unbelievably easy to make, and a total hit with even picky pups, these Frozen Sardine Dog Treats are the answer.
Made with just a few simple ingredients and no cooking required, these icy bites deliver a boost of omega-3s, protein, and flavor in every lick or crunch. Sardines are one of the best sources of healthy fats for dogs. They’re loaded with omega-3 fatty acids that support joint health, skin and coat condition, and brain function.
They’re also naturally high in protein, calcium, and B vitamins—making them a fantastic whole food to include in your dog’s diet.
This frozen treat pairs sardines with complementary, dog-safe ingredients like plain yogurt and parsley for added probiotics and fresh breath benefits. The result? A savory, icy snack that smells like heaven (to your dog!) and helps support long-term health in a fun and refreshing way.
Ideal for hot summer days, training rewards, or simply spoiling your pup the healthy way.
What You’ll Need
- 1 can of sardines in water (unsalted, no added flavors)
- ½ cup plain unsweetened yogurt (or unsweetened coconut milk for dairy-free option)
- 1 tablespoon chopped fresh parsley (optional)
- 1–2 tablespoons water (optional, to adjust consistency)
- Silicone molds or ice cube tray
Pro Tips
- Choose sardines packed in water, not oil. This avoids added fats and salt that dogs don’t need.
- Use unsweetened, plain yogurt. Avoid any flavored or sweetened varieties that may contain xylitol or added sugars.
- Chop parsley finely. It’s optional, but adds fresh breath benefits and is a safe herb in small amounts.
- Freeze in small portions. These treats are rich, so smaller sizes are best for regular use.
- Serve outside or on a mat. These treats smell fishy (which dogs love!) but can be messy as they melt.
Tools Required
- Mixing bowl
- Fork or small food processor
- Measuring spoons
- Silicone mold or ice cube tray
- Airtight container for freezer storage
Substitutions and Variations
- Dairy-free: Use unsweetened coconut milk or plain kefir instead of yogurt.
- Add-ins: Add a small spoon of ground flaxseed or chia for extra fiber and omega-3s.
- Flavor twist: Try mixing in a bit of plain canned pumpkin for extra fiber and a hint of sweetness.
- Fresh herb swap: Use mint instead of parsley for breath-freshening benefits.
Make Ahead Tips
You can easily double this recipe and make a big batch to store in the freezer. These treats keep well for up to 3 months in an airtight container.
Just pop one out when needed—great for cooling down after a walk or hiding inside a puzzle toy to keep your dog engaged.
Instructions
1. Mash the sardines
In a mixing bowl, mash the sardines (including the liquid) with a fork until smooth, or use a food processor for a finer consistency.
2. Add yogurt and parsley
Mix in the plain yogurt and chopped parsley until everything is fully combined into a thick, spoonable mixture.
3. Adjust consistency
If the mixture is too thick to pour or scoop easily, add 1–2 tablespoons of water and stir again until you reach a smooth, pourable texture.
4. Fill molds
Spoon or pour the mixture into silicone molds or ice cube trays. Fill each cavity evenly and tap gently on the counter to remove air bubbles.
5. Freeze until solid
Place the molds in the freezer for at least 3–4 hours, or until fully frozen. Overnight is best for solid texture.
6. Remove and store
Once frozen, pop the treats out of the molds and store them in a freezer-safe bag or airtight container for easy access.
Leftovers and Storage
These frozen sardine treats should always be stored in the freezer in an airtight container or freezer-safe bag. They’ll keep well for up to 3 months.
Serve straight from the freezer—no thawing required. Because of their rich smell and texture, they’re best served outside or on a washable surface.
