Sentinel Spectrum Tasty Chews Yellow (Medium Dog)

NOT CHEW-Y – ****opinion based on palpability: not any side effects*** My pup has been on *regular* Sentinal TABS for Years. Recently I switched to CHEWS (assuming) would be easier & quicker for dispensing. NOT!!! :-( They are little "bricks" which I dampen with water then cut up so my pup will even swallow!! (NO, they haven't expired) Our 2nd pup… Read more

was given a HeartGuard RX by our Vet >>>those ACTUALLY are CHEWY and crumble in my hand. ^^^So in 3 months I will stop Sentinal and switch to HEARTGUARD!!! :-)

Effective but expensive – We have used Sentinel Spectrum from the get go from when our Kelpie was a young puppy with no known side effects. She has remained fit and well for the 9 years of use. I beleive it is very important to know your dogs weight and use the drug accordingly. If your dog has only just reached the lower weight range then cut the pill in half etc and work… Read more

upward. So if 11-22kg and your dog is 12KG, cut it in half. I see too many comments for side affects, and have often wondered if its a first use / change in pill weight range. Give your pups the lower dose and work up to where your weight range is. Chat with your vet / before use. They should know what works well for which breeds and weights etc. Don't guess on your best mates health. PS, no fleas ever seen, and hope we have no heart worm either.

Extreme anxiety for my dog – I have use Sentinel Spectrum for small dogs on my dog ( a Cavalier King Charles Spaniel) without any noticeable problems, and been happy with the results(no fleas). As my dog gained weight and reached 11 kg I gave a treatment for a medium dog. I didn’t notice any problems for 24 hours but after that my dog has been sleeping constantly, salivating… Read more

excessively, chewing at his feet, refused to eat for two days. It is now 5 days since he had the dose and he has still not recovered. When I looked at the size of the doses for small and medium dogs, there is a huge difference in strengths. I can see my dog has been poisoned by having far too strong a dose. I found the advice about problems put out by the manufacturer to be totally inadequate and unhelpful. I am clearly just going to have to wait for weeks or longer for the drugs to clear out of his system.

Great product .. works well – I have used this on my Beagle for 8 yrs without any issue .. Seems to work well and never found any fleas as yet .. she swallows it whole though not sure if that makes any difference ?  Show details

Will Not Give To Dog Again – My daughter gave her dog this tablet about a month ago. A few days after giving the tablet to her dog, she became lethargic and would not eat her dog food. My daughter mentioned that her dog usually takes the tablet without any issues but this time she would not take it. She placed the tablet in her dog food, but she would not eat from her bowl… Read more

for days even after after removing the tablet and cleaning the bowl. 2 months later, I spoke with a dog owner who said her Chihuahua had to go to the vet after taking Sentinel. She said he would throw up and had seizures and that lasted for a week. I told my daughter not to give her any of the remaining tablets.

My dogs hate it – I have 3 dogs that are NOT picky eaters. They will not touch these things. They will lick peanut butter off of them. I've wrapped them with cheese. Nope. Nothing will get them to eat them.

Do not give to Australian Shepards .IMO – I have heard specific (anecdotal) reports saying it is potentially deadly for that breed. It is suspect in our niece's Australian Shepard's death, as well. That said we have given it to our three standard poodles and a husky/shepard/dobie mix successfully. Raw meat, butter or cheese is their preferred camouflage. Not peanut butter. Show details

Excellent Product – I have used Sentinel Spectrum for many years and have seen zero side affects. The product works well and we not had fleas or worms. I highly recommend it from puppy through to an aged dog. Show details

Have always used Sentinel, but no more! – We’ve had our mixed breed on Sentinel his whole life (8 yrs), and we are suddenly having a flea problem. He doesn’t have a history of fleas. I don’t know if the formula changed, or what happened, but lately it seems that the Sentinel isn’t even stopping the cycle. If I have to buy a separate pill for fleas, then what is the point to keep buying this?

Seizures after single use – My healthy happy 7.5 year old english bulldog started having seizures 8 hours after first dose. 2 months later she is on seizure meds and still suffering. Terrible chemical.

Seizures – Ever since my German Shorthaired Pointer was 3 moths old she was given Sentinel. At about 4-1/2 months she started having seizures. From that age until she was about 3-1/2she would have 8-12 petite mal seizures a year. Sometimes having cluster seziures (more than 10) in a single week. Ranging from a minimum of 30 minutes until a maximum of 1-1/2… Read more

hours. YES a minimum of 30 minutes. My vet diagnosed her as epileptic. I tried tons of different things, I received second opinions and even tried anti seizure medication and a range of different dog foods and vitamins. I recall suggesting my concern several times that sentinel could be causing the seziures. Both vets insisted that it was a safe product and it was extremely unlikely, and they were positive that Sentinel was not causing her epileptic episodes. After a while I gave up and didn't know what to do. Out of desperation I tried one last thing against my Dr's advice and stopped giving my best friend Sentinel and started her on Heart Guard. It is been almost 2 years and she has had NO seziures and lives a completely normal life. I'm sure for some dogs Sentinel is safe but the bottom line is, it was not safe for my dog. Sentinel can cause seziures and don't let anyone tell you otherwise.

My Poodle hates this stuff – We can't persuade our dog to take this med, even when coated in peanut butter, pill pockets or cheese. She eats the good stuff and leaves the med. If we chop it up and mix it with anything else she won't eat it. It's a monthly trial and we need a better product.

Very expensive – Not worth the price if you cannot receive a rebate. Paid over $100 for 12 months and was denied rebate because purchased at a warehouse.

dog has sores since taking this – I have a aussie, and just tried sentinel for heart worms and fleas, he now has sores and is constantly scratching, I have always kept him clean and groomed, I will never buy this product again and I would like my refund for the years supply I purchased. My dog is miserable and I am a mad woman. this dog has never had any sores on his body in his six years, I need a response from your company ASAP

My puppy is having a reaction – I haven't noticed any difference in fleas, although he didn't have many in the first place, only got this product to prevent them as we live in a wooded area but i have noticed that my 3 month old Great Pyrenees/Catahoula mix puppy has been itching and now has some patches coming up that look like burns. It was his second vet visit and i received… Read more

one monthly tablet to try for free, i wish i had read reviews beforehand. Any advice on what to do? I've never had a puppy have adverse effects from medicine.

Never seen a flea! – Have been using this for my two lagottos for nearly six years. One was rather wormy when we first got her but both have had no sign of pests since then .One was a bit loose in the bowels after dosing but I then realised that I should give it after her main meal not before, or with, and she is now fine.This same dog loves to eat them but the other dog must be enticed to eat the chew by putting it in a butter ball.

Would not use anything else – I have used this on my pug since he was born. He has no issued with the chew, eats it like it's a treat and has no issues. Has never had any fleas, worms or anything. Will be sticking with this one for life.

7 years on Sentinel Spectrum – My Blue Staffordshire Bull Terrier has been on Sentinel Spectrum every month for 7 years now. It's been an excellent product and I have had no negative issues to report except that I would agree that it isn't the most palatable chew for dogs. They obviously don't taste great and I do finely cut the chew and mix it into his food. There have been no… Read more ·  2

noticeable side effects physically, nor have there been any behavioural changes since having him on Sentinel Spectrum. I have read the feedback here and I am absolutely surprised about the negative comments made. Either the given dosage isn't quite right for the dogs body weight or there is something else not related to Spectrum causing these problems, maybe allergies. It seems unusual that many dogs are fine with the product and there are so many inconsistencies.

Horrible Product – What good is a tablet the dog won't eat. This is too expensive. No more Sentinel for my pets.

Puppy (sick) Given 11-22kg Pack (11 week old GSD puppy 8.5kg) - store staffs recommendation – Fingers point to this product but not 100% sure at this stage. Not given a full chew - Took a small amount off as it states 11 kg > Given 8 pm with her meal, Next day she didn't seem all that interested in any of her meals which was out of the norm. but being puppy and not sick at the time I didn't think too much of it. at 5 am next morning… Read more

(33 hours after) she was vomiting and had diarrhea, after clean up she vomited a few more times in the next hour or 2. Morning Breakfast (38 hours after) not eating as much but ate her mean somewhat with a hour gap in between, I added organic no additive pumpkin soup in it to help with the diarrhea. (She has eaten pumpkin and enjoyed it a few weeks back)

So I will see how she goes. was told by the vet to try it again in 4 weeks time if same results than its definitely the Sentinel.

No changes to diet or daily routine. - did not eat anything that she isn't given daily,

No walks outside of the house (only played in the yard as usual) and nothing was ingested at the time (nothing to ingest) Brought inside after a bit of play each time.

My other larger 8 year old GSD given the Blue pack and so far (fingers x) he is fine no issues.

Not Enough Words – I was given a beautiful Staffy/cross by my daughter, 5 years ago. Today she is gone. I had her on Sentinel for Heart Worm Preventative. Yesterday my vet told me, they no longer sell it because it doesn't work. They tested Charly and yes, she has Heart Worm. My friend, comforter and protector. This product does not work and I feel like I have let Charly down. I'm devastated. This company should be made pay for all the lived they have ruined.

This is a mixed review! – I have used Sentinel Broard Spectrum for years with my 14-year-old cattle cross dog. She has never had an adverse reaction to it, although I do have to chop it up and disguise it in her food. Sentinel works very well with her. She has never had any gastro-intestinal problems with it despite a long history of sensitivity following chemotherapy… Read more

several years ago.

However, my two young Kelpies have both had adverse reactions. 14-month-old Banjo has had diarrhea following administration, while poor little Lawson has been very unwell after his recent dose. He has had diarrhea after each dose in the past, but nothing alarming. However, this month he refused to eat his food with the Sentinel in it, so I fed it to him bit by bit. He has had vomiting, lethargy and bloody diarrhea. Thankfully after three days he is improving. When he was a young puppy, he had an episode of severe vomiting and hyper-salivation, for which the vets could not find a cause. We had another dog who had runny poop and would eat grass for a few days after his dose. He died suddenly last year from a mysterious intestinal bleed of unknown cause...3 days after his Sentinel dose. I retrospectively wonder if I killed my dog while trying to protect him from nasties.

Horrible thought. I will not use this product for the Kelpies again.

Must Taste Awful - every dose was a struggle!!! – I tried every way of giving this to our staffy and she hated it every time, Very frustrating as it's no cheap. Will be looking for an alternative next time.

Works perfect for my three dogs – We have three dogs, shih tzu, weimeraner and beagle and all three have been on sentinel since they were puppies. We have never had any fleas on our dogs and never had any instances of worms or parasites. The fact that all of this is built right in to their heartworm medication that we give every month anyway is a huge plus to me. The only downside… Read more

is they dont really take them when given as treats. I just put the pill inside a little dab of peanutbutter for each of them. Works like a charm. Would definitely recommend.

Has always worked for my dog – 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… Read more

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!
