Thanks a million.

Hallo!
To buy a puppy for breeding I can say that you need good luck- it is very difficult to decide . The important thing you can do is choose a good kennel. Which important things can you see when the Yorkshire is still a puppylook at the hairit has to be compact and black- a silver hair in this early stage means that you 'll get a a fair grey later- that's not wanted.You 'll have also a problem to determine the quality of teath from the puppy- perhaps they are not complete later. The paws and the tail may give a hint to the size of the 'ready'dog- if they are small ( the tail is thin )- the dog will likely be small. Do not choose a to small dog for breeding!
If you really want to start breeding it is better not to buy a puppy...I think you will find a good breeder who sells you a dog which is acepted for breeding- that's the better way to start.
Good luck Anja
