Sentinel for Dogs
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.
Side Effects and Warnings
Side effects of Sentinel for dogs include depression, drowsiness, vomiting, itching, hives, loss of appetite, diarrhea, or seizures. Contact your veterinarian if any effects occur.

Rated 3 out of 5 by pix10 my dog loves this medicine
My dog takes this little pill very easy and eagerly. Works well for fleas. Wish it worked for tick's too but have to buy something else for that.

by Sus1953 Sentinel one per month and no worries
I have been using Sentinel for my two dogs for six years now. There is a huge problem with Heartworm in Texas and although my dogs mostly stay inside, there is no skimping on the protection that I give them. They are my babies and thus, Sentinel is given to protect them from Heartworm, fleas, and other parasites. I give one to each once a month on the same day and I do not need to worry for the remainder of the month about whether or not they are safe.

Rated 4 out of 5 by Sbayly Good combination medication
I wish this would kill the fleas that may already be on the animal. I had to use a topical just in case they had fleas already. I do like the combination heartworm, flea, and other worm prevention. You just need to make sure the animal DOES NOT have fleas as it will not kill the ones already on the dog!

Rated 3 out of 5 by carolc720 Not Sure Yet
Two weeks ago was the first time we gave to our dog, Mandi. Mandi spit that sucker right out and we knew it was fight time... we put it in her mouth again and she seemed to be eating it but she was faking us out. Then we broke into pieces and wrapped them in some ham slices...she ate the ham but found the Sentinel. So then, we did what any good parents would do... I held her and my husband shoved whatever was left down her little throat. I can't wait until next month.
As for effectiveness, she doesn't have fleas so I guess it works.

I used to pay $150 mo for my pets flea and heartworm. Until i found petcarerx. Now i pay less than half that. Shipping takes a little bit so i recommend ordering early to keep in the cycle. Other than that, I'll never buy their meds anywhere else.

Rated 5 out of 5 by MikeyOne Great product!
easy to administer and keeps my dogs flea free for a month at a time. works on my big 'outside' dogs and my little buddies. We live near the beach and fleas are a nightmare with the warm humidity and sand. playing in the water makes the topical flea control useless.
