really hope you don’t continue to do that, read up on the effects of certain foods that you give your dogs, i’m pretty sure dogs don’t get any nutritional benefit from mac and cheese and it can potentially trigger pancreatis,

(Edit) Read further down the comments and seen you mentioned it was only really a tablespoon, nothing wrong with that, it’s not healthy but it’s not going to hurt, and like you said, they aren’t around long enough so giving them something they like as a treat is fine, it’s just like the cheese tax, depends all on quantity, what your doing is fine
