Absolutely, apples and carrots just might be the best treats for dogs and much like kids, they love them and have no idea that they are good for them (and for the love of Pete, don't tell them!). It was very good advice though to thoroughly seed the apple as I have heard before that they contain cyanide and while a few may have no effect whatsoever, many seeds over a long period of time very well may. Happy (healthy) treating!!
