i use almost anything in them i try to make them taste good together here are some of my examples:

left over mashed potatoes with meat or kibble or treats

yougurt with fruit pieces

cream cheese with meat or veggies

peanut butter with kibble or treats or fruits

thick gravy with meat or kibble or treats

soft cheese spread with meat or kibble or treats

canned dog food with treats or kibble or left over meat scraps

scrambled eggs with hash & cheese chunks


i use left over cassaroles & mac & cheese stuff like that also
these are examples I let my immagination run wild & work up many different concoctions for my furry pals!

sometimes i freeze them especially if it is liquidy or it is hot outside.
