Dog tested + for worms while on interceptor

Hello everyone,

I am wondering if anyone here has had their dog test positive for worms while on prevention. We have a lab mix who has had a lot of gastrointestinal issues since we adopted him last August. He had tape worm when he came to us, then tested positive for hookworm was treated. Then tested positive for round worm and was treated. our new vet decided to run a test following the round worm to make sure the round worms were gone. Well, we then found out hewas free of round worm, but they found whipworm! We then switched him over to Interceptor Plus in December. Keep in mind this all haPpened in a span of a few months.

we recently went through with gastro testing because Cormac has had a few more episodes of diarrhea. This last One has been horrible. So we sent out blood work and stool samples to Texas A&M. Everything came back normal except... he tested positive for round worm!

I have NEVER been late with his interceptor. Has this happened to anyone else? And did you try to get reimbursed through the company? Now I have to deworm him again and also my indoor cat since cormac has had accidents in the house. Will this ever end?!

Sorry, that's really stressful. I live in an area that doesn't have heartworm, so my dogs aren't on a preventative - we just do a routine dose of dewormer at the vet once or twice a year to flush out anything they might have picked up. So I'm not really up on the current state of affairs. Is it possible there are drug-resistant parasites in your region? Or might he be on another med or supplement that's interfering with the drug absorption? It'd certainly be worth contacting the company about reimbursement.

he wasn’t on any other medicine except a probiotic when the diarrhea surfaced this time. As for drug resistive parasites? I have no idea, but I suppose it could be a possibility. I also talk to my vet and even though the instructions say to give the same day each month, it is best to give every 30 days. So on the months where there are 31 days, I could be giving it a “day late”. Apparently the drug companies are redoing how the medicine should be administered. But his interceptor has dewormer and should maintain any worms he may pick up. Maybe I got a bad batch 😭. We will probably do the same as you and do a routine dewormer every few months to wipe anything out he may pick up.
Be cautious. Not every dewormer med will eliminate every type of worm.

Read the label. Ask your Vet about the specific worm.

I used to give Fenbendazole to my dog on a monthly basis. It is effective against several types of worms, but it is only effective against 1 type of tapeworm. It primarily targets round, hook, whip and some tapeworms. The heatworm dose of Ivermectin has an effect on some worms......sorry, not sure which other that heartworm prevention.

As always talk to your VET about the specific worm and treatment. You may need to consider placing the dog on a monthly routine of deworming. Apparently, your dog is finding a source of the worms which may be driving the repeat problem.
According to my vet his heart worm should have protected him against round worms. Interceptor plus covers 5 major parasites including round, tape, hook and whip worms. I understand that it isn’t 100% but she was as shocked as I was and believes that the company should reimburse me for the interceptor as well as the dewormer that my vet has prescribed me. I would never give dewormer medicine without clearing it with her first.
