well you know how we have a hunger bar, and if we r too hungry our health bar will go down. The tail shows the dogs health and you feed it to heal it, but it doesn't get hungry unless you hit it. Wut I'm saying is a dog getting hungry like we doIn normal vanilla Minecraft and in BC, you can tell a dog's hunger level by the heightness of it's tail. If it is at full health, it's fine. If it's all the way down and whimpering, then it needs food. I guess what I'm saying is that your request is already implemented.
