DIY Dog Treat Spinner: Make a Rotating Bottle Puzzle

A little turn, a small clatter, and a treat lands on the wooden base. That's the appeal of a DIY dog treat spinner: your dog has to figure out how to move the bottles before the reward comes out.

This homemade puzzle uses two plastic bottles, one wooden dowel and a simple frame. It is a hands-on project for adults and a supervised game for dogs that like investigating objects with their noses.

What you'll need

• Two matching clear PET bottles, about 16–20 fl oz (500–600 mL), with one screw cap each
• A broad, stable wooden base and two sturdy upright wooden supports
• One smooth dowel long enough to pass through both bottles and the supports
• Ruler, pencil, drill or awl, craft knife, sandpaper
• Wood glue and recessed fasteners, if required to make the frame rigid
• A small portion of your dog's regular dry kibble

Choose bottles that are full-length, with intact bottoms. Each bottle has a single cap at the top. The finished toy has a round kibble outlet low on the side of each bottle, not an opening cut through its base.

Before starting: Keep your dog out of the work area while cutting or drilling. An adult must remove all plastic scraps, smooth rough edges and check the wooden parts for splinters.

Step 1: Build the wooden frame

Attach the two uprights to opposite ends of the base. Keep them parallel and place their pivot holes at the same height. The base should be wide enough that the finished spinner will not topple when gently nudged.

Check the bottles against the frame before drilling anything else: the dowel should sit high enough for the entire bottle to rotate without touching the base. Press lightly on the uprights to check for wobble. Reinforce the frame if it moves.

Step 2: Mark and cut the treat outlets

Take one empty bottle and mark a small circle on the side wall just above its molded bottom. The close-up shows the position of that circle; the white ring identifies the intended outlet. Repeat at the same height on the second bottle.

With the bottle held securely and your dog away from the workbench, carefully cut each outlet. Start with an opening just wider than one piece of kibble, not a large hole. Remove all offcuts and smooth the edges.

Keep the bottoms sealed and intact. Do not add an extra bottle cap or put an outlet at the bottle's neck. Both bottles are still empty at this stage.

Step 3: Pass one dowel through both empty bottles

Near the upper body of each bottle, just below the shoulder, mark two opposite pivot holes at the same height. An adult should make the holes and smooth away any sharp plastic burrs.

Slide the wooden dowel through the first bottle and then through the second, as shown. This is the same straight rod through both bottles; the rod does not move downward in later steps.

Test that the empty bottles can rotate around the dowel without snagging. The lower treat outlets should remain well below the rod. There should still be no kibble inside either bottle.

Step 4: Mount the empty bottles on the frame

Fit the dowel carrying both empty bottles through the matching holes in the wooden uprights. Secure the rod ends so they cannot slide out or become loose during play. Keep any fasteners inaccessible to your dog.

Check the finished assembly: two full-height bottles, both upright in their resting position, caps at the top, the dowel passing across their upper bodies and the treat outlets low on their sides. Rotate each bottle once by hand to make sure it clears the base and the second bottle.

Step 5: Open a bottle and pour in the kibble

Now it's time to add the treats. Unscrew the white cap from the top of the right-hand bottle while keeping the bottle supported on the frame. Hold the cap safely aside, then pour a few pieces of dry kibble from a small bowl through the open neck. The photo captures this exact action; the left-hand bottle has not been filled yet.

Screw the cap back on firmly. You can begin with only this one filled bottle. Once your dog understands the game, fill the left bottle in the same way. Use a small portion from a normal meal rather than adding lots of extra treats.

Step 6: Check that a gentle spin releases treats

Before the dog plays, turn the filled bottle gently by hand. A few pieces of kibble should travel toward the low side opening and drop onto the wooden base.

If nothing comes out, stop and check whether the opening suits the kibble size. Make any adjustments off the frame and away from your dog, then clear up every plastic scrap. Make sure the dowel is still at its original high pivot position, the frame is stable and neither bottle can trap a paw against the supports.

Step 7: Invite your dog to try the puzzle

Move the toy to a firm, nonslip floor. Let your dog sniff it, then demonstrate one slow turn. Give your dog a moment to investigate. A light nudge that makes food fall is enough; there's no need to force the bottle into a full spin.

Start with one bottle and only a few treats. Add the second bottle when the first feels familiar. If your dog bites the plastic, repeatedly paws at the frame or seems uncomfortable, end the session and put the toy away.

Keep it safe between games

This is not a chew toy or an unattended feeder. Watch every play session. Before and after use, inspect the bottle caps, rod ends, pivot holes, treat outlets and frame. Retire any bottle that cracks, develops a sharp edge or can be pulled loose. Dogs that chew or swallow plastic should use a sturdier commercially made puzzle instead.

Wash and dry the bottles completely before refilling. Keep the spinner out of reach between sessions.

Quick questions

Can I build this without power tools?

You need a reliable way to make clean, matched holes in the wood and bottles. If you can't create smooth holes and a stable frame with the tools you have, choose a simpler enrichment project rather than compromising safety.

Should the holes be the same size?

The pivot holes should fit the dowel snugly but allow smooth rotation. The treat outlets serve a different purpose: each should be slightly larger than one piece of your dog's dry kibble. Do not confuse the two.

Do I have to fill both bottles?

No. Start by filling just one bottle. The empty second bottle can stay on the rod while your dog learns how the game works.
