We have an 18 month old Bichon too! AND her name is DAISY! We got our yorkie about 4 months ago and they are the best of friends,even from the get go. If anything, sometimes Cindy our yorkie picks on Daisy, But Daisy kinda thinks shes cindys mom,so she just takes the nips all in stride lol! So, I say go for it! They will probably get along great! Daisy was just a little shy of Cindy right at first (mabie 3 or 4 days) then they became good friends.
