What should I use when worming a pregnant female ? I normally use Ivomec inj. 1/10th cc per 10 lb .

Thank you ,
Buddy

The vet told me to use (INTERCEPTOR) 11-25 lbs. It seems to work very well.

I use the Ivomec on my pregant bitches and have never had a problem.

NEMEX II

i always use panacure or nemex.

Best time to worm her is before she's bred. If you prefer not to use Interceptor which is proven safe for pregnant dams, I wouldn't worm her at all for that 63 days. Worming her while she's pregnant won't save the pups from getting round worms. If she's ever had them in her lifetime, the pups will get them.

Roundworms in Dogs and Puppies:

STEP ONE: Toxocara eggs are passed in the host’s feces. If a fecal sample is tested, the eggs can be detected. The embryonic worm develops in the outdoor environment inside its microscopic egg for one month before it becomes able to infect a new host. If environmental conditions are favorable, it takes about a month for the egg to become infective but Toxocara eggs are famous for weathering harsh environmental conditions. Eggs can remain infective for months to years.

Note: Fresh feces is not infectious.

STEP TWO: The egg containing what is called a “second stage larva” is picked up by a dog or by some other animal. The egg hatches in the new host’s intestinal tract and the young worm burrows its way out of the intestinal tract to encyst in the host’s other body tissues. If the new host is a dog, the life cycle proceeds. If the new host is a member of another species, the larvae wait encysted until the new host is eaten by a dog.

STEP THREE: These second stage larvae can remain encysted happily for years. If the host is a dog, the larvae mostly encyst in the host’s liver. When the time comes to move on, the larvae excyst and migrate to the host’s lungs where they develop into “third stage larvae.” They burrow into the small airways and travel upward towards the host’s throat. A heavy infection can produce a serious pneumonia. When they get to the upper airways, their presence generates coughing. The worms are coughed up into the host’s throat where they are swallowed thus entering the intestinal tract for the second time in their development.

If the host is pregnant, the larvae do not migrate to the lung after they excyst; instead they home to the uterus and infect the unborn puppies. The second stage larvae make their way to the puppies’ lungs to develop into third stage larvae.

If the host is a nursing mother, second stage larvae can migrate to the mammary gland instead of the lung after excysting. Puppies can be infected by drinking their mother’s milk, though, due to the intrauterine cycle described above, the litter would probably already be infected.

Note: When dogs are dewormed, this affects only worms in the intestinal tract. It does not affect encysted larvae. It is very difficult to prevent mother to puppy transmission and routine deworming is not adequate.

STEP FOUR: Once back in the intestine, the larvae complete their maturation and begin to mate. The first eggs are laid about one week after the fourth stage larvae have arrived in the intestine and about 4-5 weeks after infection has first occurred. From here the cycle repeats.

Thanks guys !!! Bev , that's a lot of detailed information . The female has been wormed either before or shortly after the first mating .
I like the intercepter and will probably go with it during her next worming .

Thank you all for your input
