I find dogs a bit revolting so the thought of breastfeeding one is never going to be appealing.
But I'm bemused by some of the reactions on this thread. Surely that link doesn't need a warning? It's just daft, ridiculous, a bit yuck - it's not immoral or hideously offensive.
Unless, of course, you see bf as much, much more than as just a nice, cosy way of transmitting nutrition and other health benefits to your child. Which I know plenty of women do - all those on threads who say they could never bf a child that was not their own, or that they couldn't bear the thought of someone else bf their child. I bf for 22 months, I loved it, but I still never got it as this kind of quasi-spiritual bond thing.
