Yes, I know the actual size of the teacup size breed. The one we had was somewhat weight 5-6 kg. bigger than conventional size. He enjoy short running & cycling with us.
German Spitz (Mittel) might be another one to look at lattepom. They seem a very nice dog.
I agree, there is a lovely lady in my area who shows 2 of these dogs and they're just gorgeous dogs, quite compact but not as small or as 'fine' as Pomeranians.
My mum used to breed them years ago. Yes, they are very good breed. Do you know whether your neighbour have any puppies for sale? If yes, How much is she expecting for the price? Hope it's not too costly as I only got certain limit of budget. ;)
