heartgard BAD!!!

I know a number of people who use Heartguard with no problem, but my vet doesn't recommend it for Shelties so I use Interceptor. As someone else has said, unless your dog has been tested for MDR1, I wouldn't use it.

Either Interceptor or Sentinnel are good choices instead.
 
I have always used heartguard with my shelties but now with Zak I have switched to interceptor that is what his breeder uses so I decided it is time for a switch and all shelties in the future will be on it. I have never had a problem with Maggie or the Sheltie I had before her but that is not to say it could not happen.

This is the message that I've been taking to get out regarding heartworm medication and medications in general. Always monitor your dogs when starting any new medication.

All heartworm medications are on the MDR1 list at high doses. All of them not just Ivermectin. All of them are considered safe at low doses even ivermectin. But indivdual sensitives do occur regardless of breed and mutant status as shown by Sharon7's normal MDR1 dog.

From the WSU website:I only listed the heartworm meds.

Drugs that have been documented to cause problems in dogs with the MDR1 mutation include

Ivermectin (antiparasitic agent). While the dose of ivermectin used to prevent heartworm infection is SAFE in dogs with the mutation (6 micrograms per kilogram), higher doses, such as those used for treating mange (300-600 micrograms per kilogram) will cause neurological toxicity in dogs that are homozygous for the MDR1 mutation (mutant/mutant) and can cause toxicity in dogs that are heterozygous for the mutation (mutant/normal).


Selamectin, milbemycin, and moxidectin (antaparasitic agents). Similar to ivermectin, these drugs are safe in dogs with the mutation if used for heartworm prevention at the manufacturer's recommended dose. Higher doses (generally 10-20 times higher than the heartworm prevention dose) have been documented to cause neurological toxicity in dogs with the MDR1 mutation.
Selamectin is Relovution, Milbemycin is Interceptor, Moxidectin is Advantage Multi or Proheart

I used to give my shelties Hartguard until my Marcus had to have his dose increased since he gained weight. He had a toxic reaction to the increased dose. My vet reported this and was told by the company that they had reformulated it and it SHOULD NOT be dangerous to shelties. Regardless I took all my shelties off it and started using Inteceptor.

In my opinion it only takes one dog, one time to suffer and that is enough for me
 
just went back to the vet for the third round of puppy shots... and his microchip. Poor little guy is a little sore from it.

They only had Revolution- the flea and heart worm pill. Is this okay to use?

I was at a military vet for certain reasons, but I think I might make a stop at a better vet I know for advice... I wasn't too pleased with the military vet but we had to start rabies vaccinations so we don't have to go through quarantine if we get posted in Hawaii...

So- Revolution- Good? Bad? Okay?

We like it.We've had no problems,or issues with it.When Trapp came home we started using it.We have three dogs all together.
 
Our vet suggested Heartgard as a less costly option. He said there wasn't enough ivermectin in it to cause a problem. I didn't want to take a chance so I bought the Intercepter instead for Louie and Meggie but did get the Heartgard for Misty.
