I developed this peanut butter flaxseed cookie dog recipe to honor the life of my picky pup, Dylan, who recently passed. For the majority of his life, my husband and I would have to disguise healthy foods and/or medicine with something delicious to get him to eat. Peanut butter was often used, and though Dylan isn’t around to test this recipe, his canine sibling is equally as stubborn and a good candidate for testing. Read on.

Because this recipe is developed in honor of my dog, I do not offer any substitution options (with the exception of a tip for oat flour).

What Makes This Cookie Dog Recipe Irresistible and Nutritious?

Peanut Butter

According to the American Kennel Club, Peanut Butter is a good source of protein, Vitamins B, E, and Niacin. It is also the perfect ingredient for masking flavors that your canine friends may not like. Opt for varieties with no added sugars, xylitol, added sweeteners, palm oil, or salt. The label should say raw or dry roasted peanuts, and that’s it.

Honey

This ingredient contains several vitamins, potassium, calcium, magnesium, copper, and antioxidants. Check out this blog from the American Kennel Club for more information. This ingredient adds a touch of sweetness and flavor to the cookie dog recipe.

Banana

Bananas make the good list too! They’re full of potassium and perfect for snacking in moderation. They help to bind the ingredients together alongside flaxseeds.

Flaxseed

According to PetMD by Chewy, Flaxseeds contain tons of Omega-3 and Omega-6 fatty acids–the good kind. In this recipe, they serve as an “egg” to help bind the ingredients together and add flavor to the cookies.

Oat Flour

Oats are loaded with vitamins, minerals, and fiber, and they’re easily digestible. If you don’t have oat flour on hand, pulse a cup of rolled oats in the food processor to get the same result.

Wheat

According to the American Kennel Club, wheat is a great source of protein, fiber, and essential fatty acids. It should only be avoided if your dog is allergic to grains.

My other pup is a picky eater, but these cookies pass the test. In fact, he was never really interested in what I was baking UNTIL these cookies. Now, he won’t leave me alone in the kitchen!

My Best Friend

My dog, Dylan, passed on March 19, 2023. He was a little over 16 years old and my sidekick the whole time. Below are a few images from over the years, followed by an open letter to him. Feel free to jump over or click the blue “jump to recipe” button at the top of this post to skip.

Dylan-
It is hard not to dwell on your loss. You were my best friend. What you’ve given me over 16 years is irreplaceable, and to say thank you doesn’t quite sum up how I feel.

There were times when I existed because of my responsibility to you. And my responsibility to you is something I always kept sight of, a promise I made to you when you were a puppy.

You were a constant in my life, and we shared a unique bond. I can still feel your soft fur, how you would fit into my arms when I picked you up, how your cheek felt when I’d kiss it. You comforted me in difficult times, willing to lay beside me all day and night if I needed it. The good times were brighter because of you. You had your fair share of health scares, but you were a fighter and always pulled through, even against tough odds.

A few days before you passed, I picked you up; music was playing in the background. I held you close to me with both arms while gently dancing in place. You placed your head on my chest and kept it there, and I continued dancing. I knew it was probably one of the last few good moments we’d spend together. Unfortunately, I was right, and you passed a few days later. I am so thankful for you, thankful for the remaining few weeks we were able to spend together and grateful for one of my favorite last memories of you.

I truly hope you continue on, free of pain and illness, chasing waves, enjoying donut holes, and napping in the sunshine. You were the best dog, and I will always love and miss you.
