Hi Everyone, Good Morning. My chow chow won’t eat her food

. I got hey the Royal Canin Dry Food. I’ve been trying to feed her different dog foods, but she’s been so picky and she seems like eating homemade human food. But my point is, I don’t want her to get used my eating just human food, I want her to learn to eat her own food. Is anyone here owns/ owned a chow chow? Any tips of food that I can give her that’s she will like it. I really want my love to gain weight. Please. Any helpful suggestions are welcome. Thank You I’m advance
