Dehydrated Whitebait Dog Treats
These dehydrated whitebait dog treats are crunchy, protein-packed, and incredibly simple to make. Whitebait are small fish that are naturally rich in protein and omega-3 fatty acids, making them a nutritious homemade treat for dogs. They’re perfect as high-value training treats or a crispy snack for fish-loving pups.
Although our dogs loved these, the whitebait has a strong aroma when cooking. Which caused expectations in the kitchen from the dogs and cats. Windows and doors had to be open, so this is not to be made on a cold day in a sealed house!

What Are Whitebait?
Whitebait are tiny, immature fish that are eaten whole. The term “whitebait” doesn’t refer to one single species — it’s a name used for very small juvenile fish, often including sprats, herring, or sardines depending on the region.
Because they are so small and delicate, whitebait are usually cooked and eaten whole, including the bones, skin, and head. The bones are soft and edible, which means they are naturally rich in calcium and other nutrients.
Where Can You Buy Whitebait?
Whitebait are commonly found:
- In fish markets
- Frozen in supermarkets
- At seafood counters
- In Asian or Mediterranean grocery stores
In the UK, frozen whitebait is often easier to find year-round than fresh.

How To Make Dehydrated Whitebait Dog Treats
We made these in a dehydrator but you can make them in the oven. We have given oven instructions in the recipe card below. Due to the strong smell when cooking, we would advise not to make these overnight but during the day when you can have the windows open!

Place a single layer of whitebait on a dehydrator tray.

Dehydrate until crispy. Cool, then serve as a treat.
Recipe Tips
- Pat the whitebait dry before dehydrating to help them crisp up faster.
- Arrange the fish in a single layer so the air can circulate evenly.
- Smaller fish will dry more quickly than larger ones, so start checking early.
- Properly dehydrated whitebait should feel dry and crispy, not soft or chewy.
- If using the oven method, leave the door slightly open to allow moisture to escape.
- Let the treats cool completely before storing to avoid condensation in the container.
- These treats can also be crushed and sprinkled over your dog’s food as a tasty topper.
- Always introduce fish treats gradually if your dog has not eaten whitebait before.
Storage Instructions
Store in an airtight container in the refrigerator for up to 1 week.
For longer storage, freeze for up to 3 months.
Ensure the treats are completely dry before storing to prevent spoilage.

Serving Suggestions
Because these are rich fish treats, serve them as an occasional snack rather than a full meal. Smaller dogs may only need 1–2 fish at a time, while larger dogs can enjoy a few more.
