If your dog won't take the medication as an entire chew, they are easy to cut into little pieces and then just mix them in with their food. My 10 and a half year old Shih Tzu has taken Sentinel for years. It is effective. Search on the internet for the best price.

My 11 year old beagle springer spaniel cross has been on Sentinal for 5 years and in that time has never had a flea. Prior to that I tried Frontline which worked for a while then failed, and Advantix which didn't work at all. He doesn't like the taste of the chews but takes them no problem if I cut them in half and embed them in a piece of fetta cheese which he adores - to take them I make him sit or lie down or do anything else that he usually might get a treat for and he just gobbles them up! Also have had no intestinal worm problems and it is his sole heartworm protection as he is a total nightmare at the vet and needs sedation to have an injection. Love it!

I just paid $53 for 3 months of worming and flea coverage for our beloved member of the family. Open the pack - just 2 tablets!! That is $26.50 per tablet. Just crazy! Only then looked at the production line - Puerto Rico to Switzerland to Australia. Says 3 tasty chew enclosed - not this time.

I used Sentinel for dogs for the recommended 12 month period to break the flea cycle and worked a charm. I have 2 dogs; one long hair and one short hair (plus a cat) and it worked on them both. I live in the country where the fleas are unavoidable especially in the summer months and even so, my dogs were still protected. I would agree with others that it can be expensive but I think it's worth it for your pets and you not to suffer. I have been search for comparison prices online, it's surprising how many companies discount these products.
It did what it said - stopped fleas!

I have to wrestle my maltese shitzu every month ... she will not 'chew'. I have to cut in 4 and force it down her throat. She keeps spitting the pieces out and clamps her jaw ... what a nightmare. One tablet was much easier. Seems to work although as pointed out several times by others it doesn't stop the fleas.
I have only ever used this product and my dog is 11
Expensive; even harder to administer now that it is in a bigger chew; and not tasty according to my dog.

My dog has been on Sentinel all his life. The product works but it is expensive. The only drawback is that the dog will not eat it. I have tried mixing it with mince, but without success. Have worked out the only way is to shave the tablet very thinly and mix it with ice-cream. Probably the cold masks the taste.
It is reliable and works.
Bad taste ( Or so the dog thinks )

Ive had my dog on comfortis for 6 months have not seen a flea in all this time, changed to Sentinel on 12/3/2014 and by the 26/3/2014 my dog has bad fleas? i would not recommend this product to anyone and will change back to comfortis, total waste of $120 now off to spend more money changing back over, not happy at all. Im guessing the positive reviews are written by people who work for the company.

Expensive, doesnt last 2 weeks cant believe they say it will work for a month, dont buy this product

They wont eat the chew - both dogs, and so I have to chop it and try and hide it in chicken, they try to spit it out - such a hassle - Frankly I would rather put a tablet down their throat. I have two jack russell terriers who are generally good eaters. It is NOT tasty
need the drugs
they wont eat it

My staffy had a problem with fleas so I tried sentinel spectrum and my dog has not had a flea on it since. Also this product is for heart worm and intestinal worms. I have found this product to be great. I would fully recommend this product
the price is good because this product lasts along time

I think it needs to be accepted that Sentinel is not really a treatment for killing fleas already on the dog. Rather it is for stopping the breeding cycle of the fleas. If a dog is infested then you will need to use something else along with the Sentinel (like Capstar) to actually kill the fleas. I have used it for many years on my collies and shelties as safety is of prime importance in the medication sensitivity of these breeds.
Safety aspect for medication sensitive breeds.
Accepting it does not kill fleas already on the dog.

I Purchased this product as a prevention to heart worm and intestinal worms. It comes in a chewable form and I was really surprised at how easily my dog ate it and was looking for more when he had finished! Much easier to administer than those in tablet form. It was a no fuss way to treat.
My dog loved eating it.

I have a small indoors dog. I asked the pet store specifically for a flea treatment and they gave me Sentinel. My dog didn't like the chew, I had to crumble it onto a plate, and he got more fleas than ever over the next couple of days and became very distressed as he isn't used to them. Will never buy again.

Expensive. Didnt work.

I agree it's a great product.
My dog has been on them for 2.5 years with no problems until recently spending time in an infested yard, people don't realise that it does not kill adult fleas (instead prevents larvae and eggs), so if a yard or house is infested it also needs to be treated with an insecticide.
All in one treatment, easy to give dog with no hassles (just hide it in it's wet food)
Doesnt kill adult fleas

I find it is worth the extra expense because of the ease of using the product. my dogs have had it for 7 years now, and not had a flea ourbreak or anything. I feel I am buying a quality product for my dogs.
Love this product. does intestinal worms, fleas and heartworm all at once, with 1 tablet per month with a meal.I always used to forget when I did what, so this is easy - first of the month is sentinel time!my fussy dog loves the new chews so makes it easier to take ( no more hiding it in her food, only to find it spat out!)
it is expensive, how-ever you can find it cheaper on the net. I find www.pricelsspets.com.au one of the cheapest and most reliable.

This has always been a great product for my dog, a very long-haired German Shepherd. I always treat the cat with Frontline or Advantage at the same time and we haven't had fleas since, for 4-5 years now. The trouble is this used to be a palatable chew for my dog but since the formula changed a couple of years ago she's refused to take it and now clamps her very strong jaw shut so I can't even force it down her throat any more. Looking for a new product.......
It works very well
My dog won't take it

Been using Sentinel for 3 months and, despite using it exactly as per the instructions, each month we find fleas on her. Once it was a couple of weeks after the tablet, once it was a few days - it doesn't seem to do anything, as far as I can see. I'm extremely disappointed, as it's an expensive product and was recommended to me by a vet nurse - and every month we have the same problem and I have to wash everything etc to try to eliminate the fleas.

Doesn't work, hard to administer to dog
