Oh! this is very hard for me, as my last dog was 4.5kg fully grown, and she was a cutie, but have had big dogs also, which I have loved. Now I have a big dog, well not big as in Mastiff. She is about 25kg. I miss the little one cuddling up to my neck, but I like this one as she protects......so hard to make a choice.????? Help me do it ......Large for the protection, or small for the sooky baby loves and cuddles??
