Lentil and Flax Seed Dog Biscuits

I know I’m not the only dog owner out there that has had problems with their pup’s stomach, food and allergies. But I have to say sometimes it felt that way when trying to navigate these issues. My girl, Sophie of 4 1/2 years, has an immune deficiency and allergies so it’s extra important that I know what goes into her belly. I wanted to create a dog treat for her that I know her tummy could handle and came up with these crunchy lentil and flax seed dog biscuits.

I was so happy with the results, that I just had to share with all of you!

If you’ve ever had a dog that with food issues, you’ll know how important it is to keep consistency with her food and treats.  You don’t want to mix too many ingredients or proteins. So when creating a new treat for Sophie I started by looking at the ingredients she already eats in her dog food. I came up with this fun crunchy twist biscuit made with lentil flour, flax seeds, pumpkin puree and egg. These are all ingredients that she already gets and I know her system can handle.

Lentil Flour

This is the first time I’ve made lentil flour, and I’m not going to lie… it was a bit of a pain in the butt! I mean it was easy enough to do. I bought dried green lentils from bulk barn and placed them in my food processor to blend into a fine powder. The problem was, it takes forever to grind up those little lentils!! I decided to make small batches and sieve the lentils through a fine mesh while I did batches.  I had 2 cups of dried lentils and ended up with 1 cup of flour. The rest was taking too long to chop down any finer. I used The Cookie Writer’s  lentil flour directions. My note to you is to have some patience and know that this process will take longer than you expect. You may even want to give your food processor a break. If you can find lentil flour already done, I’d just buy it!  The things we’ll do for our dogs!!

Taste Test Approved

Now my dog isn’t a picky eater so I would be surprised if she didn’t like these lentil and flax seed dog biscuits. But I do know when she’s into something more than others and she lovvvvves these treats! And bonus, I feel good about giving them to her since I know exactly what they are made of (and I know her stomach is okay with all the ingredients). I passed a few treats to my brother to give to his pup Fin, and they were a hit too! So we’ve got these treats puppy approved!

I had so much fun creating this recipe for my girl, and since she doesn’t get treats often it’s nice to have something special for her. She went bananas for these dog biscuits! I mean I was basically torturing her while getting these pictures, she wanted to eat them so badly! Don’t worry, she got lots of treats after for being such a good girl.

I hope your pup loves these treats as much as Sophie and Fin does. Let me know in the comments below! Oh and if you’re wondering who Sophie is wearing 😉 ? She’s sporting Rover Boutique’s Cider Bandana, shop here!

  • Prep Time: 1 hour
  • Cook Time: 15 mins
  • Total Time: 1 hour 15 mins
  • Yield: 40 1x
  • Category: Dog Treats
  • Cuisine: Canadian


Units Scale
  • 1 cup lentil flour (from dried green lentils)
  • 2 Tablespoons flax seed
  • 5 Tablespoons water
  • 1/4 cup pumpkin puree
  • 1 egg
  • 1/2 cup dried blueberries, optional


  1. In a food processor, add lentils in batches. Blend into a powder and sieve any large lentils. This process will take lots of time to break the lentils down. Be patient. Note: I bought 2 cups lentils and was able to get 1 cup of flour, the other 1 cup I discarded as I couldn’t get the lentils any finer.
  2. Preheat oven to 350˚F and line a baking sheet with parchment paper.
  3. Soak flax seeds in a small bowl of water for 10 minutes. Discard water, after soaking.
  4. In a bowl add pumpkin puree and egg, mix together.
  5. Add flour and flax seeds (and dried blueberries if using).
  6. Mix together to form a ball. This dough is tough, you may need to use your hands to mix together.
  7. On a work surface roll out your dough in a long rectangle approx. 6 inches x 20 inches and 1/8 inch thick (it does not have to be perfect).
  8. Using a sharp knife, cut into 1/2 inch strips (cutting along the short length). See images for reference.
  9. Take each strip and gently twist. Place twists on your prepared baking sheet and bake in the oven for 12-15 minutes or until browned and crisp.
  10. Let biscuits cool before serving.

How long do they last (can they be frozen)? Buster loves them….they were honestly a pain to make – very moist and stuck like glue to my rolling pin.

A high speed blender would make very short work of those lentils. A food processor is so inefficient.

Life is uncertain, but dessert doesn't have to be!
