Sentinel for Dogs Description
Sentinel for dogs is an oral tablet for the prevention and control of flea populations, the prevention of heartworm disease and the treatment and control of roundworms, hookworms, and whipworms in dogs.
The active ingredients in Sentinel for dogs are Milbemycin oxime, a heartworm and parasite preventative, and Lufenuron, an insect growth regulator. Female fleas feeding on treated animals will produce eggs that cannot hatch. The interruption of the flea life cycle results in effective long term flea control on the pet as well as in the environment. Generally, Sentinel is well tolerated by dogs of all ages and breeds, including Collie breeds and other herding animals. Sentinel for dogs should be given with a meal. Consult your veterinarian for a recommendation on heartworm and flea prevention for your pet.

Rated 3 out of 5 by EmilyS Does not kill adult fleas
I would not recommend this to anyone who thinks their dog might come into contact with fleas. This product does nothing to fend against adult fleas so you will have to invest in other products to treat them. It is cheaper for now a very apparent reason...

You communicated with the vet to get the prescription, sent the prescription quickly, and made the whole transaction very easy. I enjoy working with you.

Rated 5 out of 5 by Buckeye Keeps away the bugs.
I have been giving this to my dogs for about 3 years. Every time the heartworm test comes due, the veterinarian has yet to find any critters in my dogs blood. It is doing exactly what I would hope it would do.

Rated 5 out of 5 by Keri No fleas!
We were using Comfortis but a friend recommended Sentinel instead. When we learned that Sentinel was cheaper than Comfortis, we were interested. But the fact that it not only took care of fleas & ticks but also worms, we were sold. We have not had one flea since beginning the treatment!
