Homemade Dog Treats

Dog treats are horrible for your dogs. I've been trying to become a dog trainer and for dog owners out there, I've got a picky dog. He hates ALL his training treats, so here is a healthy dog treat for picky dogs.
2 cups of whole wheat flour (I used King Arthur)
Peanut Butter (I didn't measure, I estimated)
1 tablespoon of Vanilla Extract
1 cup of water
Turn you oven on 350 degrees, mix I ingredients in a bowl and roll dough into ball and squish into small rounds on pan. Put in oven on 8 minute intervals (in total I did 16 minutes) until they are hard but still just a little hard. Enjoy!
