There is nothing wrong with giving *safe* people food, as long as you don't use it for more than 10-15% of their diet. I like to give a little hard boiled egg every morning or a little piece of cheese. Also, carrots, bit of apple, cauliflower, a pretzel if I'm having them, peanut butter....so just little bits and pieces of people food...gives them a little variety.
Funny 'people food' thing....our Pfeiffer LOVES coffee, btw, lol! She is *always* trying to get at my hubby's coffee and is just relentless about it at times. I think she worked at Starbucks in a former life

. Of course, a lick of it is fine - but coffee/caffeine isn't good for doggies, obviously
