Quick Safety Notes (Because Dogs Eat First and Ask Questions Never)

You control ingredients when you bake homemade dog biscuits, so you can keep things simple and safer. You still need to check a couple basics, especially with peanut butter and canned foods. You also need to keep portions small, because biscuits still count as treats.

Do this every time:

• Choose peanut butter with no xylitol (sometimes labels call it birch sugar).
• Pick plain pumpkin (not pie filling) and unsweetened applesauce when possible.
• Use tuna in water if you make the tuna recipe, and drain it well.

FYI: your dog will still beg like you never fed them once in their entire life. Dogs commit to the bit.
