Good advice. I wouldn't have thought of that either, but it does make sense since they groom each other.
Just curious though - Now what happens if Dori grooms herself?
I am very lucky that we don't have fleas - I say lucky, because it is that time of year, and our apartment building has a few dog owners and it's easy to pass them along in the main area when I am greeting and snuggling with everyone's dogs as we say hi.
So sorry you have to go through all that flea stuff. That is one subject I am still learning about, so keep me updated!
