Batch Prep: Fill and Freeze a Week of Enrichment in One Hour
Almost nobody stops using enrichment toys because they do not work. They stop because on a Tuesday evening, with a restless dog and nothing prepared, it is easier to hand over a biscuit.
The fix is not more willpower. It is doing the work once a week instead of every day. An hour on Sunday produces fourteen ready-to-go sessions, and after that the daily effort is opening the freezer.
Here is the system.
What you need
Toys: three minimum, five is better. This is the part people get wrong. With two toys, you cannot have one frozen while another is in the dishwasher and still cover two sessions a day. With five, you never run out.
Different shapes also matter, because a dog who solves the same cavity every day gets less out of it. A mixed set is more useful than five of the same thing, which is the argument for a bundle over single purchases. The bundles range covers this, and Build a Bundle lets you pick the shapes that suit your dog.
Equipment:
- A silicone ice cube tray, for portioning bulk ingredients.
- A chopstick or the handle of a teaspoon, for packing.
- A tray that fits your freezer, so toys stand upright while setting.
- Freezer bags or a lidded box.
- A marker pen.
Ingredients, bought once a week:
- Unsalted bone broth, or the makings of it.
- A tin of 100% pumpkin purée.
- Plain full-fat yoghurt.
- Their own kibble.
- One or two single-ingredient dried treats for texture.
Total cost is small, because the bulk of every fill is broth, pumpkin or their own food.
The hour, step by step
Minutes 0 to 10: portion the bulk
Open the tin of pumpkin and spoon it into an ice cube tray. Do the same with yoghurt in a second tray. Freeze both.
You are doing this because a tin of pumpkin holds far more than one dog needs and only keeps a few days in the fridge. Frozen into cubes, one cube is roughly a tablespoon and it keeps for three months. Most of a tin usually gets thrown away otherwise.
Label the bag with the date.
Minutes 10 to 20: soak the kibble
Measure out the kibble you intend to use across the week, put it in a bowl, and cover it with warm water or unsalted broth. Leave it to swell while you do the next step.
This is the most important ingredient in the system. Soaked kibble packs dense, freezes hard, lasts a long time, and comes out of your dog's existing daily ration, so it adds no calories at all.
Minutes 20 to 45: assemble, production line style
Line all your toys up on the counter, openings facing you. Then work across the row one layer at a time rather than finishing one toy at a time. It is considerably faster.
Layer 1, the back: soaked kibble, pushed down firmly with the chopstick. This is the hardest part to reach, and it should be the densest.
Layer 2, the middle: pumpkin or yoghurt, or crumbled dried treat. Vary it between toys so the week is not identical.
Layer 3, the opening: a small amount of something high value. A smear only. This is the starter, not the meal.
Then top up with broth, so it fills the gaps and freezes the whole thing into one block.
Pack tight. Air pockets are shortcuts, and thirty seconds of pressing adds ten to fifteen minutes of session time. Tap each toy on the counter between layers to settle it.
Minutes 45 to 50: freeze upright
Stand everything on the tray, opening upward, and put it in the freezer. Upright matters when you are using liquid, because it sets against the closed end instead of pooling at the opening. If a shape will not stand, prop it in a mug.
Freeze overnight. Eight hours minimum, twelve is better. A partly frozen fill has a soft centre and the dog goes straight through it.
Minutes 50 to 60: clean up and plan
Wash up, put the trays away, and bag the pumpkin and yoghurt cubes.
Then decide roughly which toy is for which day. You do not need a spreadsheet, but knowing that the biggest one is for Friday evening because you are out is worth the thirty seconds.
Vary the week deliberately
Fourteen identical fills is a wasted opportunity. Build in difficulty variation, and it costs nothing.
| Session type | Composition | Roughly |
|---|---|---|
| Easy, for the morning | Yoghurt-heavy, loosely packed | 15 to 20 min |
| Standard | Kibble base, pumpkin middle | 25 to 35 min |
| Hard, for absences | Broth base, packed dense, dry pieces suspended | 40 to 45 min |
| Very hard, for the worst evenings | Layered and frozen between layers | 45 min plus |
Aim for roughly four easy, six standard and four hard across a week. Give the hard ones when you actually need them, which for most households is the late afternoon and any absence.
Freezer management
The practical constraint nobody mentions until they hit it.
Work out your capacity before you commit. Five filled toys plus two trays of cubes takes real space. Measure a shelf.
Stack flat where the shape allows. Some formats stack, some do not. Stackable sections are the easiest to store, which is a genuine practical advantage of the FreezBrick and the FreezBrick Tower Bundle beyond what they do for layering.
Use a box or a bag so toys are not rattling loose among the peas.
Keep them at the front. If you have to dig for one, you will not.
Label the batch date. Fills keep about three months frozen. In practice you will use them within a fortnight.
Washing
Do this as one job too, not one toy at a time.
- Rinse immediately after use, so nothing dries on.
- Collect the used ones through the week.
- Run them all in one dishwasher load. Freezbone toys are dishwasher safe.
- For narrow cavities, a bottle brush gets the corners.
- Check every toy as you unload it. Any tear, crack or missing piece and it goes in the bin rather than back into rotation.
That last point is not optional. Rubber fragments cause intestinal obstructions, and the check takes two seconds.
Calories, once, properly
If you are running two sessions a day, seven days a week, the arithmetic matters.
The rule: whatever goes into the toy comes out of the bowl. Enrichment should redistribute the daily ration, not add to it.
The reason kibble is the backbone of this system is that it makes the arithmetic automatic. Take the measured portion, soak it, freeze it. Nothing added.
For everything else, keep extras under about 10% of daily calories. Unsalted broth is roughly one calorie a tablespoon. Pumpkin is about five. Peanut butter is about ninety-five. Our fill calorie table has the full list, and the pattern is consistent: the cheapest fills in calorie terms are also the longest lasting.
Use high-value ingredients as a smear at the opening, never as the body of a fill.
Single-ingredient dried treats are useful here because a small amount goes a long way and there is no label to interrogate. Crumbled cod or chicken chips suspended in broth stay solid after the liquid has gone, which stretches the end of a session. The treats and refills range is built for this.
Safety checks to build into the routine
Read the label on anything processed before it goes into a toy, every time. Shop-bought broth usually contains onion or garlic, both toxic to dogs. Sugar-free products may contain xylitol. Our list of what should never go in a treat toy covers the whole set.
Take the toy away once the food is gone. These are food enrichment toys rather than unsupervised chews. Freezbone's own guidance is that some dogs move on to chewing the rubber once the food has finished, and the toy should be removed at that point and saved for next time. It also keeps the toy interesting.
Supervise the first several sessions with any new shape.
Size correctly for your dog. A small bone holds up to 45g, and a large holds up to 90g, which is a useful reference when you are portioning a week's worth.
Scaling the system
One dog, one session a day: three toys, prep every ten days.
One dog, two sessions a day: five toys, prep weekly. This is the standard case.
Two dogs: eight to ten toys, prep weekly, and feed them in separate rooms. High-value food is the most common trigger for a disagreement between dogs who otherwise get on. The Family Value Bundle covers a multi-dog household in one purchase.
A dog on crate rest or long-term confinement: prep twice a week and keep more variety, since you are filling weeks rather than days. Our crate rest plan covers that specific situation.

Frequently asked questions
How long do frozen dog toy fills last in the freezer? Around three months if bagged or boxed. Label the batch date.
How many toys do I actually need? Three minimum, five if you run two sessions a day. One in use, one frozen, one in the wash, and spares so the routine does not break.
How long should I freeze a filled toy? Overnight, at least eight hours. A partly frozen fill has a soft centre and empties fast.
What is the cheapest thing to fill a toy with? Their own soaked kibble, which costs nothing extra because it comes out of their existing food, and unsalted broth, which is close to free in calories.
Can I freeze yoghurt and pumpkin in advance? Yes. Portion both into ice cube trays, freeze, and bag the cubes. One cube is roughly a tablespoon.
Do I need to wash the toy after every use? Rinse it straight away and run a full dishwasher load once you have several. Frozen dairy and meat residue should not sit at room temperature.
Will batch prep make my dog gain weight? Not if the fills come out of their daily ration. Weight gain happens when enrichment is added on top of normal meals rather than replacing part of them.
