> i'm looking into getting one of these breeds
Donna, please remember that, if you're buying a puppy, then you will not be able to walk it for hours.
The "golden rule" for dogs of
any breed, is 5 minutes walk per month of age. So, at 3 months, that means 15 minutes walk per day. And that is literally 7.5 minutes there, and 7.5 minutes back. Take into consideration just how much sleep a 3 month old needs. And just how much exercise they will get at home, just from normal playing, both in the house, and in the garden.
My Yorkies love exercise, but they were limited to the 5 minute rule, and built up gradually, an extra 5 minutes per month. If you know all this - I'm not trying to teach you to suck eggs, but it is always important that newbies know the rules too! :-)
