Freeze-dried fish pieces for a dog's puzzle toy

Fish treats for puzzle toys start with small pieces. None of our listings mention puzzles, but they do tell you how to break each fish: sardines and anchovies into pieces for rewards, heads into a crumble. Break first, load the toy, count it all as treats, and stay in the room.

Can you put freeze-dried fish in a puzzle toy?

Nothing on any of our listings says yes or no to puzzle toys, so this page is our own application of the serving words the listings do use. We make no claim about what a puzzle does for your dog, and we have nothing to say about how dogs take to them.

What we can say is simple. The fish are whole, freeze-dried raw, one ingredient each, made in small batches in Malvern, Pennsylvania from imported fish. The listings say they are treats or toppers, not a complete diet. The pieces you load into a toy are those same treats, in smaller bits.

That makes a puzzle session a treat session. The share, the supervision and the handwashing all come with it.

Which fish break into pieces small enough for a puzzle?

Here is what each listing says about breaking or crumbling.

• Sardines: break into smaller pieces for rewards, or crumble as a topper.
• Anchovies: break into pieces for rewards.
• Sardine heads: a crumbled topper is the listing's small-piece form.
• Minnows: whole, or crumbled over food. They are sold out now, and the button reads "Sold out, back soon."

The Fish Trio page adds a comparison. It calls the sardines the largest of the three and the anchovies smaller and drier. That is the page's observation, not a measurement, and the listings give no lengths or piece counts.

Both the freeze-dried anchovies and the whole sardines break by hand. Break either until the pieces fit your toy and your dog's mouth. If you are loading a snuffle mat with crumbs, crumble. If the toy has a slot, break to the slot.

How much fish goes into one puzzle session?

The same amount as any other treat session, because the toy changes how the pieces arrive and not how many calories they carry.

For dogs, the sardine listing's FAQ says: "Hold all treats to about 10 percent of the day's calories." Our treat calculator uses 10 percent as its default, and the note on the sardine page credits VCA's treat guidance for it. That figure is for dogs.

Take your dog's daily calories from the food bag or your veterinarian, then use the label's energy figure. The sardine label reads approximately 94.9 kcal per ounce, and the anchovy label reads approximately 83.1. The calculator on the sardine and anchovy pages turns that into grams and ounces. It gives weight only.

So weigh the day's share, break it, and load it. Once it is in the toy, it counts as given, so do not stack more treats on top of it later.

How do you keep handling raw fish tidy?

The fish are freeze-dried raw, so treat the bag and the pieces as raw. The sardine heads listing says: "This is raw fish, so wash your hands after handling it." Wash after you break the fish and after you load the toy.

Break the fish over a plate or a cutting board, so the crumbs land in one place. Reseal the bag, and keep it cool and dry. The sardine and anchovy listings both say no refrigerator is needed.

Wipe the toy or mat down after the session, and keep your hands off your phone until you have washed. It is not glamorous, and it is the same tidy-bench habit as keeping tools off the floor.

Should you stay nearby while your dog works a puzzle?

Yes. Every listing says to supervise while feeding, and a puzzle toy is still feeding. So stay in the room.

That also means a filled puzzle is not something to leave out for later. When you leave, take it with you. The fish bones are in the fish. We make no bone claim of our own, and the anchovy and heads listings both send the question of fish and your own dog to your veterinarian.
