Do you know how she caught it? Is she an indoor dog?

What is an ACD?

From what I understand from my vet if a dog is on heartworm preventative and gets heartworm, the manufacturer will cover the cost of treatment. Check with you vet about this.

I've never used that 6 month type because when it came out I read something that didn't sit well with me. I don't even remember what I read. You could probably find a lot on it via google.

Yes, the treatment is lousy. Send me a private email if you wish.

Like people, all dogs are unique and may react differently to drugs/medicines. And remember, some medicines do not mix well with some foods. Inform the vet immediately. They may have an alternate brand to use. On the other hand, you may wish to get a second opinion from another vet.

Good luck.

Our vet recently notified us that they would no longer be giving the injections due to some type of recall...we had to go back to the edible type. Downside is that we have to force our dogs to eat them, they just don't like them at all. Here is an article on the recall:

FDA recalls popular heartworm drug for dogs

Did your dog test for microfillia or did he get the occult test? The occult test looks for actual heartworms in the heart and is the only definite diagnosis. Circulating microfiliia are just young heartworms in the blood and will be removed with preventatives.

Be very careful with the different prevetatives! Some breeds ( and mixes thereof) are sensitive to ivermectin and can die from it! Collies are one such breed; ACD might be on that list too.
