Emily, did you find what you wanted in the 2 posts? I don't recall Jill's post but you can search in the box for it in archives if these 2 aren't what you want.
I thought I did the right thing posting about what I heard saves puppies. I'm ordering them for my next litter. A friend had them on her links page & says it works terrific. I hope I didn't post the wrong item.
I love using a Delee mucus trap! Works fantastic! I get mine very reasonably priced from Whelpwise http://www.whelpwise.com/mucus-traps.html but the above link has a similar one even cheaper!
