Welcome! My name isXXXXX am a UC Davis graduate, and currently, a Medical Director of a veterinary hospital.
I am sorry to hear about this concern for Fergus.
Normally, I encourage rechecking a stool sample about 7 days after medication is finished using these guidelines:
Bring in a fresh poop sample to the veterinarian. Ideally, within a few hours. Request that it be sent “OUT” to the laboratory instead of being looked at in the hospital (more accurate that way). We are not interested in only worm eggs, but also checking for the very common microscopic bugs like giardia and coccidia. These types of parasites will not be cured with over-the-counter dewormers. Giardia can also be difficult to identify on routine fecal tests, so ask your vet if they always add a “giardia elisa” to the fecal test. Here is more detailed information about fecal testing:Fecal Testing
Also, my suggestions:
1. Stop the Wellness Core
2. Stop all treats....EVERYTHING...
Start a regular premium puppy food like Science Diet or Royal Canin. Ignore anything about ingredients, if it has corn, etc...
Just do a regular premium diet.
I have time and time again had many problems with these high protein or ultraholistic diets.
So, you must stop all treats and the Wellness Core, as one very well is the source of your problem.
Also, ask the vet to do a empirical treatment with panacur suspension.
I recommend at least a 5 day course at 50mg/kg once a day. Vet will understand.
Please let me know if there is anything I did not cover for you. I hope that information has been helpful.
