I'm sure her left ear will go up in time. Luckily, she eats her high-quality Innova puppy food readily. I would think that the Innova has adequate calcium for puppies but I'm not sure. She also likes chewing on her little deer/elk antler, which is supposed to be a good source of calcium. I am keeping the top 1/3 of the inside and outside of her ears shaved. If her left ear doesn't start standing in a couple of weeks, I will try feeding her plain Greek yogurt or cottage cheese. Thank you for that suggestion.
