We give ours fresh carrots. I use to give the younger pup bananas (fresh & frozen), but he stopped liking them. He use to eat little pieces of apples & blueberries too but same as bananas he stopped liking them, guess as he went from puppy stage to adult (mind you he is only 3 yrs old) he decided he didn't want them anymore. Our senior dog has never like fruit, but she will snack on a carrot, lol. You can't say CHEESE or crinkle a cheese bag without the younger one come running in the kitchen, lol. It's like his crack! haha. Even if you can get it out without making a noise he literally can smell it from the other room and come to investigate. He's too damn cute for my own good, I can tell you. And Lord the boy is smart! I thought our senior girl was smart, he picks things up faster than she ever did. Typically all our male dogs were not as smart or quick to learn, so was surprised what a fast learner he is, and so ready to learn too.
