How to Use a KONG Fill & Freeze Tray

At UPCO, we love finding products that make life easier for pet parents while also keeping dogs happy and entertained. One of our favorite tools for enrichment is the KONG Fill & Freeze Tray—the perfect accessory to take your dog’s KONG toys to the next level!

If you’ve ever struggled with filling a KONG neatly or wished you could prep a few in advance, this tray is a game-changer. Here’s how to use it and why your pup will thank you.

Step 1: Prep the Goodies

Start by choosing your dog’s favorite KONG toy and a tasty filler. Popular options include:

  • KONG Treat Paste

  • Peanut butter (unsweetened, xylitol-free)

  • Wet dog food

  • Plain yogurt

  • Mashed banana or pumpkin puree

  • Kibble softened with a little broth

Pro tip: Mix and match ingredients for variety!

Step 2: Use the Tray to Hold the KONGs

Place your KONGs upright in the specially designed Fill & Freeze Tray. The tray keeps them steady, so you don’t have to worry about spills while you’re filling them up. No more trying to balance them against a counter or cup—just set them in the tray and you’re good to go.

Step 3: Fill With Ease

Now that your KONGs are secure, spoon or squeeze in your chosen filling. Because the tray keeps them stable, you can fill each one neatly without the mess.

Step 4: Freeze for Long-Lasting Fun

Once filled, pop the whole tray in your freezer. Within a few hours, you’ll have frozen KONGs ready to keep your dog busy and satisfied. Frozen KONGs last longer, making them especially helpful for dogs with extra energy or those who get anxious when left alone.

Step 5: Serve & Rotate

When it’s treat time, simply grab a frozen KONG from the tray and give it to your pup. You can prepare multiple KONGs in advance, so you’ll always have one on hand for playtime, crate time, or quiet time.

Why We Recommend the Fill & Freeze Tray

  • Convenience: Prep several KONGs at once.

  • Less Mess: Keeps KONGs upright while filling and freezing.

  • Happy Dogs: Provides long-lasting enrichment and mental stimulation.

We love this product because it turns an already great toy into a simple, mess-free solution for everyday enrichment.

If your dog already enjoys KONGs, the Fill & Freeze Tray will make your life easier and your pup’s playtime even better!
