question on dewormers

**VTJess03** · 09-25-2006, 03:38 PM

Why is it that vets recommend rotating dewormers for livestock, but not for dogs/cats?

I asked a vet if I should rotate my dog onto a new dewormer, and he said no as long as I didn't see any problems with it, but there wasn't enough time for me to ask him why not (and he was really busy that day, besides). It's not like it was a particularly pressing issue, so I thought I'd ask y'all.

I'm not even sure what that means, so now I am curious!

Maybe because livestock is susceptable to more kinds of worms that dogs
than dogs are. I've never heard of rotating a dogs preventive. If it works,
why change it?

Not all livestock dewormers get all kinds of worms. They have to be rotated to ensure all the different types are eleminated.

Pet dewormers(at least the good ones) get all the different types of worms at once so no need to rotate.

I asked the boss about this one, he said livestock can get a variety of worms, and that worms can sometimes be resistant to wormers, hence the reason for rotation of dewormer meds.

There is no such thing! There are several different meds for many of the worms/parasites that cats/dogs can have (whips, rounds, hooks, tape, coccidia etc.). It's a myth that one dewormer does everything. The reason we don't rotate in pets is they don't get worms as often as livestock and don't become resistant to the dewormers.

No need to yell. Just repeating what my vet told me--it's why I don't use the substantially cheaper Panacur & Strongid anymore and pay 600 bucks a year for Drontral Plus instead.

Actually, Glacier is right. Drontal Plus, which is the wormer my Vets use, treats all common canine/feline intestinal worms such as hookworms, roundworms, whipworms and tapeworms.
