The guy whose ferrets were lost to something-or-other doesn't come into contact with the fuzzies at work; we quarantine pretty carefully. Usually, the only diseases we see are fish with fin rot or the occasional case of a hamster with wet tail, but the rules are fairly strict... I wanted to add a note of encouragement to the discussion of the puppy and ferret situation. My friend Melissa has a slew of ferrets (actually only four), as well as a dog and a couple of cats. My fuzzies go over and play quite a bit, too, so her dog has 10 ferret friends. Granted, he's a beagle, not a huge animal, but he really loves the ferrets. My Tesseract is his favorite--he'll chase her all over the house, and she'll chase him back, nipping at his toes. He would never hurt one of them, even by accident--he doesn't mouth them at all, and is careful of where he steps. I think, since you're teaching Merlin ferret manners starting in puppyhood, by the time he's the huge beautiful fella he's going to be, he'll be sleeping with them at night. :-) Remember what we fert folks like to tell other people? Baby ferrets are nippy, just like baby dogs. Both need affectionate handling and consistent training. It sounds like what you're doing is just about perfect--let your baby dog know it's okay to play with the ferrets, but not to chew on them at all. You should have seen me with my cats and ferrets--when I brought home my first kit, and my half-grown Maine Coon adopted her, I was actually kind of terrified. It looked like they were being so rough! Now, though, I know that Zephyr (the cat) is an absolutely wonderful surrogate ferret. A silver mitt, even! Later I brought home Amadeo, only a baby, at the same time as I was helping a cat raise four-week-old kittens. The little cinnamon climbed into the box with the kittens, snuggled down, and screamed bloody murder if I tried to take him out of there. For three days I hardly saw him, and he never did anything to hurt the kittens. The mother cat seemed to accept him--cleaned him like her own, and even nursed him once or twice... Anyway, all this is just my way of saying that ferrets can coexist peacefully with just about anything they don't want to eat. Sometimes it just takes a little work. Good luck!
