Measuring your dog To measure your dog, use a ruler, calipers, or a measuring tape to find the width of their jaw behind their canines. Only include their jaw and teeth, do not include lips/jowls. Try to measure to the closest half centimeter and if your dog is between sizes, select the larger size. How to Use Your Bite Block Training Using a bite block requires some foundation training. Your dog should first learn a reliable “hold” behavior before you ask them to hold the bite block. The bite block is more challenging than other objects because it requires a wider mouth opening and is made of a solid material that’s less naturally appealing to hold. Don’t rush the process—once your dog understands “hold” across a variety of objects, they’ll be able to generalize the skill to the bite block more easily. Start simple: Begin with an intuitive object like a toy Progress to a wooden or PVC dowel Then introduce the bite block Below is a good video on teaching this skills.

However, 3d printed items are not typically classified as food safe because the printing process creates tiny gaps in between the layers that can be difficult to completely sanitize. To prevent the spread of disease and bacteria between dogs, I recommend using a different bite block for each dog.
