Last dog loved fruits and veggies. I would regularly give him pumpkin, sweet potatoes, green beans. He would patiently wait and stare at anyone eating a banana, knowing he'd get the last bite. And when we were done with an apple,, we'd hold the core and he would nibble it with his front nippy teeth like it was corn on the cob. It was hilarious taking him blackberry picking with me, he'd find the ripe ones and carefully nibble them off the briars as to not get prickled. No tomatoes, melons, or squash in the garden were ever safe from him. Except cukes. He did not like cukes.
New pup is getting a raw carrot every day, to clean his teeth and to deworm. And it gives him something other than my table legs to chew on. He has also had sweet potatoes and pumpkin, and likes those. After he is completely housebroken, I'll introduce more veggies into his diet.
