Very similar to our situation. They only go outside when we are walking them, and we have a rule and we stick to it: Clean their paws with at least water on a paper towel when we get inside, every time - would you wear a pair of dirty shoes to bed?? And of course, wash with anti-bacterial soap IF they do manage to get into something on their walks. Also, we check their butts reguarly to be sure everything came out AOK

Our little girl does get her anal glands manually cleaned when necessary...
I think with these types of precautions, there is no problem with them sleeping on our bed, and we've been doing that for about 16 years now with no issues we know of. I do not let them on our pillows, and not even on the sheets, only on the blanket or spread on top.
