Preheat your oven to 200 degrees Fahrenheit (95 deg Celsius).
While the oven is heating remove the skin if still on (it can be harmful to your dog) and also any excess fat from the chicken.
Turn the chicken breast on its side so that you can use a paring knife to meat into 3-4mm strips.
Put the strips on a baking sheet and bake for 2 hours.
It is in a slow oven, so it’s drying out process so that the finished product is dry and hard.
Before removing the Chicken from the oven, check that it is dry and hard, not soft or chewy.
Cool before you allow your dog to have some.
Store in an airtight container in the fridge for up to two weeks.
