I have 2 dogs that are on Sentinel 51-100lbs Flavor Tabs. I have a
male American Bulldog named Sully who is almost 100lbs and a female
Rottweiler named Corey who is 103lbs and they were both born on March
18, 2003 and are 18 months old.

What should I give my 103lb Rotty b/c she is over 100lbs, and I can't
seem to find any preventatives for dogs over 100lbs?

Is Sentinel a good preventative against Heartworm, Fleas and other
worms?

We are located in East Rochester, NY. I bring my pupz to the park a
lot and there are many other animals there like dogs and horses.
There are also a lot of cats and dogs in my neighborhood. They are
always kept up to date w/ all their shots. I just want to make sure I
am giving them the correct medz to protect them.

Milbemycin prevents heartworm in dogs at a dose of .05 mg/lb. (See
http://www.fda.gov/cvm/efoi/section2/140915s060498.html) That means your
103 lb. dog would need about 5.15 mg. Since Interceptor Green contains
5.75 mg of the drug, you should be able to easily prevent heartworm in
your big Rottie.

As for fleas and worms, in my house we treat for these things as they
occur instead of giving pesticides on a regular basis. The decision
between taking that approach and being proactive is one you will have to
make with your vet. In which case you can ask him or her what meds to
use should the need arise.
