Just recently I have come to realize how hard it is to get rid of hookworms in retired racing greyhounds. I work for a company called https://cluejay.com/add-on-fec/ and recently a FB customer reached out to us from a group called "Getting rid of parasites in retired greyhounds". She explained the need for the McMaster's testing and how nice it would be to test from home. After much research and correlation with our lab we have chosen to offer this to our customers as as "Ad-on" to a Level 1, 2 or 3 test. We have since gained a lot of interested customers and we are excited to help this community! A veterinarian consultation to discuss any health findings is a available as well by reaching out through email or chat:)
