Are Lemons OK for dogs? - lemons for dogs

I have a Yorkie 9mnth age, and Sunday, ate lemons and whistled, and had a piece of lemon that I managed to take by mouth. Lemon seemed to enjoy it. I just wanted to know, lemon is not bad for dogs with acidicness? What is the impact, if any? No stupid comments please, thank you!
