why do you even want to give them a bath? I wouldn't give puppies that young a bath unless the mother wasn't caring for them, as she is licking the pups so much. I'd be afraid they would get chilled otherwise
Never trust a tall dwarf... he's lying about something.
I agree with the above posts. Only give them a 'butt bath' if the mother isn't doing her job. Even then, don't just put them back with the litter right away. Make absolutely sure they are dry and warm before you put them back with the litter. You don't want them to get chilled. Even if they live after being chilled, they will never be as good as pups as they could have been.
