Welcome, Louise and Milo!! Your little boy is downright ADORABLE!
Everyone already gave some great advice regarding his ears and food. If you're interested in learning about Raw Diet at all, you can search for "Kat's Prey Model Cheat Sheet" in the Food section; I tried to target it for raw beginners as I also foster small dogs and give it out with any adopted dog.
Anyway I look forward to seeing you around and getting to know you and Milo! =D
