lol.... I wouldn't lose much sleep about them hurting themselves
Of course you have to be careful and watch that they don't get into trouble
just like you would with any dog
But don't baby them
You'd be surprised at what they can do
Mine are 3 months and they need help getting on the couch
but if they see something down on the floor that looks interesting they go sailing into the air and OFF they GO!
They're tuff little guys
