pup's now I agree that they must respect your wishes if you really want to wait the 12 weeks,but at 10 weeks they are ready.I would ask have they owned a small dog before and if so I think everything should be fine.
as far as buying I would wait the longest I could to make sure I won't get an oversized one.I think 7lbs would be my limit maybe but that is me.
I am sure you will make the right decision for you and they will fall in line. |
