Product Detail: Sentinel Spectrum Chewables

Sentinel Spectrum Chewables For Dogs

Sentinel Spectrum is manufactured by Novartis Animal Health Australasia Pty Ltd as a broad spectrum preventative medication against many common canine parasites.

This product is given as a once monthly oral dose and is flavoured to enhance palatability for dogs.

Dogs should be tested for heartworm by their veterinarian prior to beginning on Sentinel Spectrum.

Sentinel Spectrum aids in the control of fleas by ensuring that the life cycle of the flea is interrupted at several stages by interrupting the development of juvenile stages of the flea. Sentinel Spectrum does not kill adult fleas. Another product which kills adult fleas may be required occasionally to kill any adult fleas on the animal.

All animals in the household should be on an effective flea prevention program to ensure maximal effect of this product.

How to use the product

Sentinel Spectrum is given as an oral dosage once a month, preferably on the same date each month. It should be given with a full meal.

Animals are dosed according to weight and as such a growing animal's weight will need to be monitored to ensure the correct dose is given each month during the animal's growth phase.

Treatment can begin at 2 weeks of age in puppies but needs to be given again at 4, 8 and 12 weeks of age before continuing on the regular monthly dosing schedule.


Four different sizes of product are available, each given according to the animal's weight.

  1. Dogs up to 4kg - orange pack
  2. Dogs 4-11kg - green pack
  3. Dogs 11-22kg - yellow pack
  4. Dogs 22-45kg - blue pack

Dogs over 45kg are dosed with the appropriate combination of tablets to equate to their weight. The packs are available in 6 and 12 packs.

Tips and tricks

In order to ensure continuity of coverage with Sentinel Spectrum, doses should be given on the same date each month. Many owners find the 1st of each month to be an easy date to remember. Dose dates should be recorded on the calendar for easy reference.

Sentinel Spectrum are a flavoured chewable tablet so dogs should readily accept the dosage. If they do not accept the tablet it can be given by placing the tablet at the back of the dog's tongue in the middle and then holding the muzzle closed and the head slightly elevated until the dog swallows. A veterinarian or veterinary nurse may be able to teach you this technique if required.

Dogs should only be given the tablet appropriate for their weight. Tablets should not be split and shared between animals.

In the case of severe flea infestations, a thorough cleaning of the animal's environment and bedding is recommended at the start of treatment.

Sentinel Spectrum contains 3 active ingredients

  1. Milbemycin oxime

Contraindications and warnings

Awesome Sauce!!!

I give this to my 3 beloved Boston Terriers to protect them from heartworms, intestinal worms and fleas. It works beautifully! I trust Sentinel with my dogs' lives and do not regret it. Only the best for my girls!

This product may cost a little more than the other heartworm meds but its like 2 products in one. During the flea season I was buying flea medicine and heartworm medicine and with 7 dogs it gets very costly. It takes a couple of months for the product to work if you have a flea problem but it works.

Perfect Product

I have close relatives, farm folk, whose house and 3 indoor dogs are perpetually, amazingly infested with fleas. We have to visit regularly because we love them and our kids need them. The first time our new puppy visited with us he picked up over 50 fleas, which I picked off one by one. We tried numerous products, largely ineffective, until Sentinel arrived in our lives. For 3 years, we have had not a flea in our home, and if one is lurking, it is alone! It is one of the parts of life that is actually working right.

I bought sentinel from Joe's Pet meds about a year age. I have been nervous since then about my NEMO getting heart worms. He was due for his yearly shots anyway, so I took him to the vet on Monday. They tested him and he was negative! No worries, this stuff works!
