Sentinel Spectrum Chewables

Sentinel Spectrum is a once-a-month chewable tablet that contains a combination of milbeycin oxime, praziquantel, and lufenuron to prevent and control fleas, heartworm and intestinal worms in dogs. Milbemycin oxime interferes with nerve transmission and helps protect against heartworm, roundworm, hookworm, and whipworm. Praziquantel causes muscle spasms and kills tapeworms. Lufenuron is an insect growth regulator, which is used to control fleas by preventing the development of flea eggs.

Item Specifications:

Sentinel Spectrum is a highly palatable beef-flavored chewable tablet that provides broad spectrum parasite protection.

Use this product because it covers more than heartworm and fleas. They have made the Spectrum more broad based in its protection.

because it was less expensive than what we used last year and still has the same coverage
Elizabeth A on Jun 30, 2018
The dogs like it. They think it's a treat. We've had trouble getting our dogs to take other pill-form medication. This is soft and they chew it right down.

I have been using this product for a number of years and have found it to be effective without side effects.
Onia G on Mar 6, 2018
It works.
WILLIAM R on Feb 27, 2018
Love that I do not have to buy separate prescriptions for Flea, Tick, worms and heart worm. One stop shopping to cover all parasites. Nice to give one chewable that my dogs like and I don't have to remember multiple medicines.
Jennifer M on Feb 7, 2018
Have used it for years.

Includes protection from tapworm vs regular Sentinel which would require a second medication.

We have used this for years on our older dog. Works well.

Need for my dog
Cassandra S on Sep 28, 2017
This is MUCH cheaper here than at the vet. My dog is, shall we say, peculiar with taking his medications. They are wrapped in lunchmeat. With this product, I can cut them into decent sizes pieces for him to take. Being able to do this, is a TREMANDOUS help. Thanks for the product.

work on ticks?
ken n on Feb 3, 2018
BEST ANSWER: I live in upper Michigan were there are a lot of ticks. Along with Sentinel Spectrum I use Freedom 45 just to be double safe. So far have never seen a tick on her. Because of the amount of ticks in our area I'm not relying on one product.
Are these tabs flavored?
A shopper on Mar 21, 2018
BEST ANSWER: They must not be super yummy. One of my dogs will eat it but the other one spits it out unless I put meat or cheese around the tablet.
How many chewables per pack?
A shopper on Mar 13, 2018
BEST ANSWER: They offer a choice for a 6 count or a 1 count pill.
Do I need a prescription for sentinel spectrum?
Carol W on Oct 16, 2017
BEST ANSWER: Yes, this is a prescription item.
