Ingredients and What They Bring to the Smoothie
Just a handful of simple, easy-to-find ingredients are all you need. Here’s what each one contributes:
- Creamy Peanut Butter – Adds rich, nutty flavor, protein, and creaminess.
- Banana – Adds natural sweetness and fruity flavor while helping thicken the smoothie.
- Plain Greek Yogurt – Gives the smoothie a creamy consistency while adding protein and calcium.
- Lite Coconut Milk – Provides the liquid needed for blending and adds creaminess with a mild coconut flavor.
- Old-Fashioned Rolled Oats – Add fiber and help thicken the smoothie.

Ingredient Notes and Substitutions
Choosing the right ingredients is important, and there are several easy substitutions you can make. Here’s what to keep in mind:
- Peanut Butter – Always check the label to make sure it does not contain xylitol, an artificial sweetener that is toxic to dogs. Choose plain, unsweetened creamy peanut butter when possible.
- Peanut Butter Substitutes – You can substitute peanut butter with almond butter or sunflower seed butter. Make sure whichever one you use is xylitol-free.
- Coconut Milk – You can substitute coconut milk with unsweetened non-dairy milk such as almond milk or oat milk. Goat milk is another good option.
- Greek Yogurt – You can substitute Greek yogurt with regular plain yogurt. Greek yogurt generally contains less lactose and may be easier for some dogs to tolerate. Low-fat cottage cheese is another option. Always use plain, unsweetened yogurt and never use yogurt containing xylitol.

Other Great Uses for the Smoothie
A bowl isn’t the only way your pup can enjoy this creamy treat. There are several fun ways to serve it for a little variety and enrichment.
- Enrichment Toy – Pour it into a Kong or similar fillable dog toy and freeze it for a longer-lasting treat.

- Frozen Treats – Pour the smoothie into silicone molds and freeze until solid.
- Lick Mat – Spread a thin layer over a lick mat and serve immediately or freeze it for a longer-lasting activity.
How to Store the Smoothie and How Long It Lasts
Store leftover smoothie in an airtight container in the refrigerator for up to 2 days. It may separate as it sits, so shake or blend it again before serving if needed.
For longer storage, pour the smoothie into an ice cube tray and freeze until solid. Transfer the frozen cubes to a freezer-safe container or plastic freezer bag and store them in the freezer for up to 3 months.
