Definatly ask about a health guaarantee.....and make sure the parents are on site for you to look at...... lets see,.... i asked about weight, FOOD (find out what food they are eating so you can switch it gradualy) , i asked about the ears if they would go up or not (coz i wanted them to stay floppy
), i asked how much the parent weighed...... i asked SO many questions i cant remember them all!!
Mainly, if the breeder is a good one, they should be asking you lots of questions as well, because a good breeder wont give their puppies to just anyone.........
