I have an 11 lb Poodle (10 yrs old) and Kiwi (Yorkie) is just over one year old. They are both spayed. They get along fine playing. Sometimes Kiwi gets a little territorial about where Pebbles can sleep on the bed

But other than that they are great together. Good Luck in your search!
PS My dad is from Glasgow-I have never been but hear your country is so beautiful.
