Hello,
Some of you may remember that my lovely girl went away to a friend who then took her to be mated. I was very careful to worm and do flea treatments before she went and got pregnant. BUT it seems she may have visitors....OMG. She has come home with more than pups !!!!
What treatments are safe when in whelp? What can I safely use to stop things getting worse?

THANKS....

frontline spray is safe for pregnant and lactating bitches and pups from 2 days old
