I'm trying Sue but Riley is so freaken picky when it comes to food. How often would you recommend feeding? The only way I can get him to eat the soft food is if I put water in it and then he just licks the water out and he's done. I'm afraid he's not getting enough nutrition and his back leg muscle is really thin. He begs for hard food and I don't know if I should just give it to him so he doesn't starve. As soon as I do that his # go up. He doesn't like freeze dried treats either or chicken.
