Flax Seed Homemade Dog Biscuits 

I guess you could say that my dogs are super spoiled, but I’m ok with that! 😉 They love going on long hikes with us, playing fetch, basking in the sun, and chasing birds in the backyard.

My dogs went crazy for these little treats! I made them extra special by using a small dog bone cookie cutter.  You can make them as big or as small as you like and even save time by cutting the dough with a knife or pizza wheel instead of a cookie-cutter. 

We will often make several batches of these dog biscuits and take them to our local dog shelter. They always welcome the treats, and naturally, the dogs are more than happy to snack on them. If you have a local shelter that you like to donate to, this is a fun way to make a donation. It’s always appreciated at any time of year too. 

What If I Don’t Have Dog Biscuit Cookie Cutter 

That’s not a problem at all. I like to make these homemade dog biscuits with a little dog bone because I think they are absolutely adorable. However, you can make them into any shape that you like. Circles, squares, rectangles, or any other cookie cutter shape will do. Your doggie isn’t going to care what shape they are as long as you are giving them some treats. So go wild, have fun, and make as many playful dog treat shapes as you want. There aren’t any wrong answers here, so don’t stress over it. 

How to Store Homemade Dog Biscuits 

I recommend keeping the dog treats cold and in the refrigerator after they are finished being made. Let the flax seed dog biscuits cool down all the way first. After they have chilled, go ahead and place them inside a food storage container or special dog treat container. Keep them refrigerated for 7-10 days, and they will be good. They may start to go bad after that, so you don’t want to risk giving your pup a stomachache. 

Tips For Making Dog Treats

Making dog treats is actually a lot of fun. You can make all sorts of adjustments to this recipe and change things to make different flavors. Your doggie is going to be so thrilled that you are giving them such a yummy treat compared to the store bought stuff. Homemade treats are so much healthier! Let’s take a look at a few tips. 

  • If your dog is gluten-free, you can swap the flour for a gluten-free flour instead. Flax Seed is naturally gluten-free, so there shouldn’t be any problems there. 
  • Be sure to measure all of the ingredients properly. If you don’t, the texture may be off, and they will either fall apart. 
  • Use a silicone baking mat whenever possible to prevent the dog treats from sticking to the pan and breaking when you try to move them. 
  • You can also bake them inside of oven safe silicone molds to make different shapes. Just make sure they are oven safe, so you don’t end up with a disaster. 
  • Add a little bit of an egg wash to the treats right before baking if you want them to be shiny and extra pretty. 
  • Feel free to add your favorite add ins to the recipe. Peanut butter, mashed banana, meats, fruits, and veggies all have different flavors to offer. 
  • Never ever ever add alcoholic drinks, avocados, garlic, coffee, candies, apple seeds, cherry pits, grapes, old foods, raisins, mushrooms, or other foods that are bad for dogs. Not only can they become ill, but many can also cause bowel obstructions as well. 


All you need are ten ingredients to make these simple flax seed dog biscuits. You can also add in other ingredients that you think your dog may enjoy, such as mashed pumpkin or peanut butter. 

  • Whole wheat flour
  • Bread flour
  • Wheat germ
  • Salt
  • Brown sugar
  • Flax Seed
  • Large eggs
  • Vegetable oil
  • Powdered dry milk
  • Water

How to Make Homemade Dog Biscuits

First Step: Combine the bread flour, wheat flour, wheat germ, brown sugar, salt, and flax seed in a large bowl. Use a whisk to combine and set aside. 

Second Step: Dissolve the powdered dry milk in the water in a separate medium bowl. Add in the eggs and vegetable oil and whisk until they are combined. 

Third Step: Using a rubber spatula, combine the wet and dry ingredients together until they are combined. Leave the dog biscuit dough in the bowl, cover with a cloth and allow it to sit for 15-20 minutes. 

Fourth Step: Heat the oven to 375 degrees and line your baking sheets with parchment paper or use silicone mats. 

Fifth Step: Place the homemade dog biscuit dough on a work surface that has been lightly floured. Then roll out the dough into a rectangle that is around 1/2 inch thick. Cut the dough with cookie cutters or any other shape that you like. Place the cut biscuits on a cookie sheet and bake them for 35 – 40 minutes. The biscuits should be brown and really hard like a rock. 

Sixth Step: Take the flax seed dog biscuits off the baking sheet and put on cooling racks. Let the biscuits cool down all the way before you store them.
