Ummmm...animals/dogs don't come potty trained. These kiddos are just 12 weeks old - they wouldn't be anywhere *near* being potty trained at this age. So, I'm a little confused by your post - were you expecting them to be potty trained at this age and know they shouldn't poop inside certain things?
What kind of plan / book / guide are you using for potty training? If you want to PM me your email - I do have a potty training guide I could email you in pdf form.
