When preparing homemade dog treats, make sure you take into account any allergies that your pet has to specific ingredients. You will want to avoid adding any ingredient that you know that your pet has reacted poorly to in the past. If you are experimenting with new flavors, feed the treat to your dog in a small amount to see how he reacts to it before distributing an entire treat. Store your homemade dog treats in an airtight container and place them in the freezer. Allow the treat to thaw for 10 – 20 minutes prior to serving to your dog. Treats can last for up to 6 months in the freezer.
