Hello & welcome, I am Dr. B, a licensed veterinarian & I would like to help you with your wee one today.

Now how to approach this properly will depend on when you collected the stool sample. If it was taken and analysed before the Ivermectin was used, this wormer may clear the burden (and a 2nd sample could be analysed to ensure that was the case). Otherwise, if the sample is since treatment and thus a sign of treatment failure (though if it was given today, this is unlikely), then we'd want to use an alternative wormer. Those we would use in this situation include Fenbendazole (which can be used as a paste, liquid, or medicated feed) or Albendazolesince both can be used with Ivermectin. Just to note since you used the Ivermectin today, we'd avoid Moxidectin since it is the same drug class and there would be risk of interaction. But again if the Ivermectin was given since the results, we'd not rush to re-worm unless we have a 2nd positive sample.

Please take care,

Dr. B.
