hi, It's been a while since i last posted, so hi!! Ok the other day i got a card in the mail from my vet asking me to make an appointment for a blood test for my dog for heartworm. It said that its dangerous to give your dog heartworm meds w/o making sure he/she doesnt have the worms. But i've been going there w/ the ferrets longer than the dog, and they've never mentioned a blood test for ferrets. I've assumed since its dangerous to give a dog heartworm meds w/o checking for the worm, wouldnt it be dangerous for ferrets too??? Are ferrets suppose to get a blood test once a year for heartworms too?? Please let me know soon since heartworm season is just around the corner! Thanx, Karri & f 'rats [Posted in FML issue 1863]
