Can it be possible for a dog to test negative for worms twice even though I have physically seen them?

Question

Ive showed the vet and they just keep giving her the same thing and her fecal comes back negative? What should I do?

Also she does not have fleas and she does not go outside she is the only pet in the home. They have been giving her Drontal.

Answer 1

It absolutely is possible for her fecal test to come up negative for worms, even though she has them. When they do a fecal test they look for intestinal parasite eggs under the microscope. Intestinal parasites do not shed eggs at a constant rate. They only shed them at certain times. So they may have not been shedding when you had her tested. And some worms, like tape worms, can be seen physically by a human eye, but are hard to find on the microscope. And this could be what your dog has.

If this were my dog I would just do what the vet suggests. If it is not working, talk to them about it, ask whatelse you can do. If you still think it isn't helping, I might see another veterinarian. Good Luck, I hope you get rid of the worms soon!!

I also wanted to add the sewwood.. is right. She could be reinfecting herself. You will have to ask your vet how your dog could have got these worms, and how to avoid getting them again. An example is tape worms come from eating fleas or rodents. Animals who has fleas can get treated for tapeworms, but it they are not also treated for fleas, then they can just keep reinfecting themself.

Answer 2

If you are seeing the worms then it is one of the forms of tapeworm.
Flea tapeworm is caused by the ingection of fleas. Treat your pet for fleas and give her a popantel tapewormer tablet now and then again in 6 weeks time.
Spirometra This one is far more difficult to treat and comes from farming land, eating frogs / lizards. It requires 3 times the normal dose of worming and several doses.
Hydatic Tapeworm (doubtful) As above.

Get your vet to send a sample of the worms to a endoparasite specialist at your local university they will identify the type of worm and give them the life cycle and how to best treat the worm.
We did this when we had a dog present with a worm we had never seen before and it turned out to be a weird worm that only sheep get and somehow the dog had got them!!

Answer 3

Yes it is possible. Your dog has tapeworms if they look like little peices of rice. Fecal tests are done under the microscope, this picks up the eggs for roundworms, whipworms and hookworms, but tapeworm eggs are too big to be seen through a microscope, and you pretty much have to just see the worm segments with your eyes and tell the vet you are seeing tapeworm. Ask him for a Cestex pill, this will get rid of those and only those worms. But if you don't get rid of the fleas on the dog, he will get reinfested with these worms over and over. They get them from swallowing a flea while they are grooming themselves and the flea has the tapeworm larvae inside of them.

Answer 4

No - and it's bad practice. Find another vet. If you haev tested the dog in the past month, and then start giving the vet-dispecsed pills on time, the manufacturer of the pills will cover the ocst of treating your dog for heartworm, whould they test positive later on. They are aware that the pills aren't 100% even when given on time, so they will cover the costs - but not if the test was 6 months old. This 6 month thing isn't good medicine. You really need another vet.

Answer 5

Assume that you have Tape worms they do not show in fecal exams and are seen by sight in stool. The prefered wormers for Tape are Safe Guard, Panacur and Droncit. Tape worms come from flea bites.

Answer 6

Don't waste time money or stress on a vet that is willing to test for worms +x. My dogs are active and exposed so I worm 3x a year. A cold winter is the only low exposure stretch I won't. My sister is a veterinarian so I use lopotol by weight 3weeks apart every 4 months. NO WORRIES! If your yard dirt has been contaminated by round worm eggs you could have a chronic reinfection issue.

Answer 7

I would say it is possible, but if your vet isn't listening to you and your concerns I would say it is time to find a new vet. Tape worms are different from heart worms are different from hundreds of types of worms that can infect a dog. Have them do a blood test, bring a sample of the worms you see and then see what the vet does.

Answer 8

It may be tapeworms which are very hard to find on a fecal sample. Most intestinal parasites shed eggs periodically so then you have had the fecal checked the parasites may not be shedding eggs.

Answer 9

Try D-Worm there are two kinds get both of them as you may have a problem with tape worms also.

Are your dogs in a situation where they can eat wild animals or cat poop? this will make it seem like an on going thing even tho it would be considered *reoccurring*

GOOD LUCK

Answer 10

If you have seen them, I guess your dog has them. Why the test is showing negative, who knows. What is your vets answer?
