|Yes, 10 weeks is a tiny tot! :) Precious!
It's amazing to me how smart dogs are. Like little children, they add gradually to their vocabularies -- knowing about 200 words as they get older. I ask my dogs if they want to go "pee pee" and they run for the back door! If I ask if they are hungry, they run to the place I feed them, etc. Smart little critters.
Your little Milo will learn your words soon enough, and by his actions can tell you a lot about his wants and needs.
Have fun teaching him, and learning from him, too! Pets are a real blessing from God!
