do you keep your dog on heartworm preventative

year-round?
I ask cause when I took Molly in this spring for her heartworm testing vet mentioned to me that they now suggest a dog stay on this all year - prevents intestinal parasites as well as heartworm.
I hesitate though mostly because I don't see the point when there are no mosquitoes in NH winters. She didn't/doesn't have intestinal parasites nor do I anticipate her being in a situation where that would happen. The most common being tapeworm from fleas and no flea problem no tapeworms. She doesn't go to dog parks so there is no problem w/being exposed to fecal matter of other dogs.
What do you do?

 

I do it year round, but I also work at a kennel and don't want to accidently carry something home. Also, I use revolution, so it does fleas, ticks, heartworm, and mange, so I don't ever stop. I'm also in Texas, where it seems like there are mosquitos year round.

 

I usually stop 2-3 months December to February, because from what I read the heartworm larvae need like 5 days 24/7 60 degree temp to produce. But I got to thinking, last winter, we were still in the 30/40 at night and 50s in the day an I saw mosquitos! so what if they get into my house and reproduce in the warm home?

 

My old dogwas on it year round for a fe years, but I eventually stopped the year round, she was also on the flea and heartworm medicine. I did it only in the summer.
With Luther, he has never taken the heartworm meds. He just takes the flea meds, occasionally.

 

Not far south of Houston they have an annual Mosquito Festival so that should indicate our situation. I keep the boys on Sentinel all year.

 

My brood stays on Interceptor. I'm not risking it.

I dont' use any topical or oral flea and tick preventative. They get brewers yeast and a bit of garlic powder daily. That keeps everything away!
