What age is too old or too young to begin giving my puppy heartworm medication?
I have a Pug puppy who is about 7 months old. She has shots but I want to begin giving her preventative heartworm medication as soon as possible, but I heard something about having to do it before a certain age… Is that true? I think someone told me that I need to start it by 6 months of age… Will it be just as effective if I start now? I’m hoping it’s not true about needing to get it before 6 months… I’m just wondering what the facts are.
Thanks!

FACT- you can still start the dog on Heart worm preventative like Interceptor monthly. BUT….you need to take the dog to the VET first & have a Heart worm test done, to make sure your dog doesn’t already have adult heart worms, if your dog does, then giving a preventative instead of treatment can actually be very harmful to your dog.
You need to talk with your Veterinarian about a heart worm test & then starting the dog on a monthly preventative.
Rogue Bullies-your VET may have something different.
My VET however requires a test before the preventative. My VET doesn’t even carry heart-guard!!!
So NO I’m not wrong, you are just being an idiot.
