Our pups love frozen green beans! They are a real treat for them. Our big dog Quinn (lab) gets a few when we leave for work/school and Charlotte (yorkie) gets a few little pieces here and there. They both love apple! For dinner they get veges mixed in with their food, Quinn gets mixed veges and Charlotte gets petite peas. For the longest time she'd pick out the peas and spit the puppy food on the floor till the peas were gone then she'd eat the kibbles. LOL It was so cute.
They love when I peel carrots, I'll shave some off and they run off with the pieces like it's candy. hehehe
