Best Prices for Sentinel Blue

By: Bernadette on 22 November 2018
I always shop around for the best prices of Sentinel. The Vet Shed was by far the most competitive, and that's including postage. No point in buying online if the postage is too high is there? It's good to know The Vet Shed looks after it's customers.

The ease of using Sentinel Spectrum Blue

By: peter a beaumont on 28 October 2018
I find it so easy to give ONE tablet each to my cattle dogs each month. I have been using this product for years and the dogs have never had fleas or worms. Good delivery by The Vet Shed. Very prompt.


By: Kirsten Walker on 22 September 2018
Works in preventing the lot including the important heartworm as well as the fleas and ticks and all in one easy chew that the dogs simply gobble down. No topical liquid applications needed that can be messy and a bit of effort. I like this product.

Have been using Sentinel for dogs 23-45kg for our very active Lab for several years now, and while she has not like to chew them voluntarily for some time, it does give her excellent coverage and protection, very happy withe the product especially since we take her our daily to the beach and through forshore and paddocks etc. We usually order through the Vet shed as they are usually competitive on price and delivery is very fast.

Chocolate flavoured chews are the way to go! No more inserting little white tablets and holding slobbery jaws closed. These chews are regarded as a treat

Sentinel for large dogs.

By: Mrs. Jacky Freeman on 15 April 2016
Buddy is a Golden Retriever so he will eat anything! He loves his Sentinel ,it's like a treat for him. We love Sentinel because it takes care of fleas & worms in one easy dose. We have used it for years for all our dogs, & even the 12 yr old dog wasn't bothered by fleas, which is often the case as they get older. We wouldn't change our brand now as we are more than happy with Sentinel.

He thinks they're treats!!

I have used this product on my pooch for six months now and I am very impressed. It keeps my American Staffordshire Terrier free from all nasties just like it says it will. I don't have to force feed him the chews either, he loves them and takes them like treats! Highly recommend this.

I love these chews. My dogs scoff them and I can rest assured knowing they are fully protected from all those nasties like fleas, worms and ticks.

Sensational Sentinel!

This product is excellent - a compact chew that leaves no mess and ticks all the boxes (pardon the pun) for worms and parasites!

Sentinel Blue Chews 23-45kg 6 pack

18 November 2013
Our Rottix kelpie has been taking Sentinel Spectrum for many years. I like it because it covers flea and worm (including heart worm) protection in one dose once a month, very convenient. She likes it too and we just put it in with her dinner. This product has never let us down and has no side effects.

Sentinel Spectrum is what we recommend

By: The Vet Shed on 29 December 2011
Sentinel is easy to use and covers so much. This suits us. No fleas, no worms and no chance of getting heartworm. Dogs happy and so are we

So Easy!

By: Carrie on 25 September 2011
Fantastic product. Easy once-a-month tablet covers pretty much everything. My dogs have never been sick and also have never had even 1 flea whilst using Sentinel. So easy and good value compared to buying Wormers + Heart Wormer + Flea prevention. Does not prevent ticks but our vet advised that she has never found a product that does anyway, daily checking is best. Will never choose another product :-)
