Feedback on Idea

Things for me continue to evolve...I am trying to land on something I can do while I still work full time.  I want what I do to center around baking as well.  So I have come up with this idea and would like to get feedback on things I need to be aware of or potential problems I could run into.  I have researched those fruits and veggies that are safe and good for dogs.  Veterinarians like the idea of fruits and veggies for snacks rather than other more fattening treats.  Many of the veggies and fruits have other added benefits that the store bought treats do not.  Just think if I could create lots of these as well as my desserts in a jar...maybe I could sell them at a craft show...I'd have to also research the shelf life of these products as well.  I could sell ready made desserts and breads in a jar; cookies, cake, and bread mixes in a jar and all natural dog treats in a jar.  What do you think?  What do you feel I should be aware of?
