Why aren't couples having sex? According to this survey, most of the time it's because of financial stresses. A third of the time, however, it's the dog's fault. Mind you, this is a British survey, so you may need to factor in the stoic British passive aggressiveness.

"Yes, it's Fido's fault we haven't had sex in a while."

"Indubitably, darling, were it not for the dog's snoring, we would be banging right now."

"Yes, bad dog! Snoring...and leaving the toilet seat up, boy, I do hate that! Bad dog!"

"Well, in that case, don't forget how...Fido...forgets to balance the checkbook and we get an huge overdraught fee for going over only a few quid. Bad dog!"

Via.
