There’s a freezer trick that can make goodbyes easier. Here is why this simple calming routine helps anxious dogs relax when you leave…

Separation anxiety can cause issues for you & your dog. For example, a common form of a dog’s separation anxiety would be for them to whine, bark, pace back & forth, destroy items, and have bathroom accidents once you leave them for a few hours alone.

We recommend using frozen Kongs as a way to keep dogs busy, calm, & emotionally stable when they are left alone, so let’s find out how!

Why Frozen Kongs Work for Separation Anxiety

A frozen Kong is more than just a food puzzle. It combines mental stimulation, soothing licking, and a long-lasting reward that helps your dog associate your departure with something positive.

1. Licking Helps Calm the Nervous System

Licking is a self-soothing behavior for dogs. It encourages slower breathing and provides a repetitive action that can reduce anxious energy.

2. Mental Work Reduces Panic

A dog that has to work for food is a dog that is less focused on your leaving. The challenge of getting the reward out of the toy gives their brain something productive to do.

3. Frozen Texture Makes It Last Longer

Freezing the filling extends the time your dog stays occupied. Instead of finishing a treat in minutes, they may stay engaged for 20 to 40 minutes, which is often the most difficult part of being alone.

How to Build the Perfect Frozen Kong

You want the filling to be safe, dog-friendly, and appealing enough to keep your dog interested.

Good Filling Ideas

• Plain peanut butter with no xylitol
• Pumpkin puree
• Plain Greek yogurt
• Mashed banana
• Goat milk yogurt
• Wet dog food

How to Prepare It

1. Choose a Kong-style rubber toy that fits your dog’s size.
2. Layer in a few soft ingredients to create a “trap” that makes the filling harder to get out.
3. Add a final layer of a tasty topping.
4. Freeze for several hours before use.
5. Give it to your dog right before you leave.

Helpful Tips

• Start with short absences so your dog learns the routine.
• Reserve frozen Kongs for departures, crate time, or calm-alone practice.
• If your dog is a fast eater, pack the filling tightly for a longer challenge.

Most dogs benefit from them, especially dogs that get anxious when left alone. Just be sure the toy is the right size and durable enough for your dog’s chewing style.
