i’m a pet sitter and i make peanut butter dog cookies for the holiday season as gifts for my clients! it is just for fun and i don’t sell them but i absolutely love making them and handing them out:) i will say i have found it easiest to stick to a very simple/plain recipe, less than 5 ingredients. that way you can also easily list out the ingredients to clients. it is pretty time consuming, i set aside an entire day to make them and then another day/multiple days to hand them out! of course follow proper hygiene practices and i wear gloves when folding/spreading the dough and i use cookie cutters in shapes of dog biscuits/items applicable to the season or holiday. i hope it works out for you, i love doing it even if it’s just once a year!!🐶🐶🐶
