Hi! I have recently fostered a 7 month old puppy who I found on the side of the road. She was just skin and bones. She was a picky eater too, but she absolutely loved the raw food I made for my dogs. I would recommend you feed your dog raw food, but if you’re not up for that (which is totally fine) you could top her kibble with things like boiled chicken, raw eggs, homemade bone broth, or cottage cheese. Keep the Tail Wagging is a wonderful blog by someone who shares lots of tips about raw feeding and holistic care, and I use her recipe for bone broth. I hope this helps!
