I don't know about other dogs, but ours love most vegetables. Aside from tomatoes, they eat lettuce, raw spinach, and raw broccoli like it's candy. They hear the rustling of the plastic bag of broccoli or spinach and come running.
I'm so glad you two are doing that - sunflowers are so rewarding for kids (and adults). She'll be thrilled with them, because they practically grow six inches/day. Whether or not she likes radishes, those are quite rewarding to watch grow, too.My daughter has decided to plant sunflower seeds. They are in a pot so they won't get big, but they are blooming. This is the first time she has planted anything and she is so excited. She is in the planning stages for next year. I would love it if she decided to be my yard person. I dislike yardwork with a passion.
