Candi had the runs this past Thursday. It had a little bit of blood in it. Took her to the vet and they tested a stool sample. They put her on Royal Canin Gastrointestinal prescription diet. She gets 1/4 cup about four times a day. They just called and said that she is positive for whip worms (?) and hook worms. First of all, is there such a thing as whip worms or did I mistake that for round worms? Second of all, my partner will be picking up her medicine this evening, since I don't drive. I could walk there but with temps -25 below zero...that's not an option. So while Candi IS being treated for this...is this something to freak out about? Out of all of our pets, she is the only one that has/had worms. Thanks.
