My 14lbs Schnoodle has been on Sentinal for the past 7 years. I usually put the pill in peanut butter and she eats it happily. This past month when she saw me getting it prepared she ran and hid, once I found her (in her usual hiding spot) she did take it reluctantly. That night she was in and out of the house all night with and upset stomach. I’m beginning to wonder if this happens every time I giver her this medicine and I’m just now catching on (thanks to her hiding). She’s usually very healthy, but on occasion has these stomach issues at night. Anyone else notice this? Thanks!
My 7 kg Cavoodle is about to take his first dose of Sentinel spectrum. Am I giving him one full green Sentinel spectrum chews or do I need to cut it? Because it says suitable for 4-11 kg.

I can't remember if I gave my dog Sentinal Spectrum on 1st December when she was due. Should I give her one now (12th Dec) just in case & then every month on 12th or could it be dangerous?
You can quite safely give your dog another Sentinal dose, but next month take the date from the date you gave the SECOND dose and not the first - so if you usually dose on the 1st of the month, and cant remember, and you give your dog a dose on the 17th, make next months dose the 17th of the month. Hope this helps!
Gave my dog freedom 45. It didnt seem to work. Got his sentinel refilled. When am I able to use it? He is a yorkie kid weighs 12.65 pounds.
You should ask your vet rather than relying on possibly incorrect advice sourced from here. It depends on if the active ingredients may interact, when you last treated your dog, how old your dog is, and whether you are trying to deal with worms or fleas.
I would ring the Vet Nurse at your regular Veterinary Clinic and ask, and I am certain that they will be happy to correctly and safely advise you. Sometimes ingredients should not be combined if you have recently dosed your dog, so please ask a Professional rather than risk your dog's health by taking a lay-persons help. Best of luck with your little Yorkie! :) Cheers NatNat
Does it prevent ticks as well?
Does giving your dog a bath affect the effectiveness of sentinel?
I can't say for certain, since I've never heard of that possibility. My uneducated guess is that baths would have no effect.
I doubt it very much. There is nothing in the instructions to suggest that wetting or bathing your dog would have any impact. A vet would know for sure.
Hi, my dog has eaten the chew but approx 12 hours later has vomitted. Does this mean that the treatment is ineffective? Should we give him another chew?
He used to have advocate liquid on his back, although this would affect his mood and make him very withdrawn and somewhat depressed.
Hi, i would suggest calling the vet and asking them, my dog had a bad skin reaction to sentinal (not sure thats correct spelling) its taken a month for her to be clear of all irritations
Does sentinel spectrum kill the fleas or just prevent the eggs from hatching? Vs Trifexis I think Trifexis will kill and prevent but Sentinel does not kill only prevents hatching is this correct? I need to know ASAP will have to buy one or the other tomorrow when my dogs get checked.
Is there a better alternative than Sentinel Spectrum as my dog wont accept it. Even cut up fine in her food does'nt work as once she smells it she leaves her food
Ive read other reviews on flea/heartworm treatments and some have alarming side effects
I have a dog that will not take these chews unless I make a small ball of butter with the chew inside then she wolfs it down.
Given my little dog sentinal flea and worm treatment 5 days ago still can see fleas. I don't think it's working! Can I give another flea treatment to my little dog without harming him like comfortis?
Hi, i wouldnt give your dog anymore oral flea treatment if she has already had the Sentinel tablet. The tabs actually kill eggs and therefore stop future fleas from hatching. You might just have to give your dog a good bath with flea shampoo to kill the existing adult fleas. Once gone hopefully all should be good for you. Goodluck.
I agree with Kristen. I would bath your dog to remove existing fleas. I bath my girls in teatree shampoo for dogs . Its available at Coles. It works well. Good luck.
Does my dog need to be heartworm tested before i start him on Sentinel, and how about ticks? I have fleas and ticks?!!
Yes, your vet will have to test your dog for heartworms prior to getting sentinel as it is dangerous for your dog to take sentinel if it is heartworm positive. Sentinel will control fleas by preventing the eggs from hatching, but it does nothing for ticks. You would have to use a separate product like frontline to prevent ticks. :( You might also ask your vet about Revolution, it's topical and applied monthly if I remember correctly. I believe it prevents heartworms and also prevents fleas and ticks.
Can this cause vomitting on small dogs?
I have only german shepherds. But my sister-in-law had a small dog and it didn't cause vomiting with Karma.
Can I give my dog capstar if he's already on Sentinel spectrum?
Vet gave Sentinel for our dog to kill the baby heart worms, in 3 months will give treatment to kill adult and youth heart worms. My dog is one day out from the first phase , and today doesn't have any energy. Unable to hold urine, laying down all the time, doesn't have the energy to go to feed and water bowls. Do we need to call bet, or will he start to feel better as days hp?
Hi Charlotte, I thought Sentinel was used for prevention, not cure of an existing problem. My dog has never had any adverse reactions and he is over 2 years old. As a matter of fact, he had his monthly tablet today, shaved finely in yoghurt. There is no way he will eat the tablet on his own. I would take the dog back to the Vet as soon as possible.
Hi my son has put his dog on sentinel it could have been a coincidence but she developed severe itching redness from scratching in patches and had to go on antibiotics and cream and medicated wash got that cleared up and he gave her next dose 10 days ago and the scratching is back could the dog be allergic to this product ? Thanks for any ideas pam
i use it on my dog and i have never had a problem.i use advance to kill the fleas and sentinel for worms and flea cycle control.and i do it every month and my dog has never had any problems ever.the best thing to do is ask your vet.because i find that very strange because i know other people that use the product and they all say it works great.
