I have a retired racing greyhound that has capillaria. The vet has tried ivermectin, and two rounds of panacure, but he still has them. Any other ideas as to what to try?

There is no approved treatment but ivermectin is considered to the treatment of choice for Capillaria in dogs (apart from Collie breeds and dogs with the MDR1 mutation); levamisole, fenbendazole and albendazole have been reported as being effective as well. Regards Dr Callum Turner DVM

I am fostering an English Setter from upstate NY breeder who died. Initial vet check found Capillaria eucoleus boehmi. She was given a dose of Intercepter through a shot. That was seven days ago. I have two questions: Is she contageous to my other two dogs? And how long before i should check another feces? My vet has not treated a dog with this. Thank

I don’t have specific data on the use of Interceptor (milbemycin oxime/praziquantel) but its use is similar to ivermectin which has shown favourable results within two weeks. I would recommend having another faecal test after two weeks, four week and then each month for a few months to be on the safe side along with regular administration of anthelmintics.

Hi! I have a pup that when she urinates a small white worms comes out. She's had a fecal test done, no parasites found. And has also been treated for tapeworms(2 weeks ago) Any idea what this might be? Any info helps! Thank you :)

It sounds like Keima may have Capillaria plica which is a small threadlike roundworm 15-60mm in length and white to yellow in colour; they normally stay in the bladder or upper urinary tract and most dogs are asymptomatic. Treatment using ivermectin is usually sufficient; after treatment take a urine sample for analysis at your Veterinarian’s office (note to other readers, ivermectin isn’t to be used in Collie breeds and isn’t approved for use in dogs).
