Rice versus barley groats

I would like to use barley instead of rice in my homemade dog food. Can I just replace the rice with barley? It's locally sourced, more filling (dog on a diet) and perhaps a little better nutritionally?

• Yes, it's perfectly fine to switch! It's also a good idea if your dog needs to lose weight 👍🏼
• 👍
• Oh, we have someone on a diet here too! Do you use the same amount of groats as rice?
• Yep, you can use the same amount 😄
