JadeD, I wish your daughter a glorious birthday and an amazing year.
I, too, have two wonderful Yorkie mixes and adore them. Actually, my little girlie just went to her first Barn Hunt class last Tues and did nicely. Yes, I plan on getting my mix a title.
I do have purebred dogs for working, etc, but I am also happily owned and manipulated by some rather interesting mixes - Shoot, I'm a mix breed myself. So, there.
I do think insurance is an excellent idea, purebreed or mix.
Congratulations and happy Birthday to your beautiful daughter again.
