About this product
1. What is Sentinel Spectrum for Dogs?
Answer
Sentinel Spectrum protects your pet dog from tapeworms, intestinal worms, heartworm, and fleas. The bacon and beef flavors often liked by dogs allow them to accept the medicine directly from your hand. As it is in tablet form and therefore, there are no restrictions to your pet being washed or swimming post-treatment. The key benefits of Sentinel Spectrum are: It protects your pet from six varieties of parasites, namely fleas, tapeworm, roundworm, hookworm, whipworm, and heartworm. The lufenuron present in the medicine prevents the flea eggs from hatching. You need to give your pet a dosage of one tablet every month.
2. Is Sentinel Spectrum Safe for Pregnant Dogs?
Answer
Yes, pregnant and lactating dogs can be given Sentinel Spectrum and it is completely safe. Although Sentinel Spectrum is a safe medicine, it can have some adverse effects. Check the Sentinel medicine for its ingredients and ensure that your pet dog is not sensitive to any of them. Only give medicine to your pregnant dog if it is prescribed by a registered vet. Although being considered safe, go with the advice of your veterinarian, whether to use it or not.
3. What Does Sentinel Spectrum for Dogs Prevent?
Answer
Ease out your pet’s flea and heartworm issues with Sentinel Spectrum. One dose per month can protect your dog from six varieties of parasites, namely fleas, tapeworm, roundworm, hookworm, whipworm, and heartworm. The medicine requires a prescription from a registered veterinarian.
4. Is Sentinel Spectrum Good for Dogs?
Answer
If your dog is facing parasite-related issues, then Sentinel Spectrum can be of good help for its prevention. It prevents fleas reproduction and is potent against heartworms in dogs. The dogs like the beef flavor and take it as a treat rather than a medicine. It is also very effective against intestinal worms like whipworms, hookworms, tapeworms, and roundworms and destroys the flea eggs before hatching. Sentinel Spectrum should only be administered on dogs exceeding six months and should only be given once a month.
5. What is the Difference Between Sentinel and Sentinel Spectrum for Dogs?
Answer
Both Sentinel and Sentinel Spectrum are very effective and the best medicines in their category. Both the Sentinel medicines have Lufenuron and Milbemycin Oxime as their main ingredients. Both can be bought on prescription only, comes in beef flavor, and are in chewable form. The dosage of both the medicines is also the same and should be taken only once a month. Both provide effective results against heartworms and fleas and prevent the flea eggs from hatching. Both are safe to be used in pregnant, breeding, and lactating dogs. They both are also safe to be used in puppies. Sentinel can be used in puppies over the age of 4 months. However, Sentinel Spectrum can only be given to puppies over six months and weigh more than 2 pounds. The second difference between the two medicines is that Sentinel Spectrum has one additional ingredient, Praziquantel. This extra content is potent against tapeworms.
6. Will Sentinel Spectrum Kill Fleas?
Answer
The medicine does not kill the adult fleas instantly but kills the fleas at very early stages and thus stops the flea life cycle. The grown-up fleas that we usually see on our pet dog are only a minute problem. But there are several thousand flea eggs, pupae, and larvae present in dog beddings, floorboards, carpets, etc. These then turn into adult fleas that come on your pet dog. Stopping this environment stage is important, which is the role of Sentinel Spectrum. It destroys the flea eggs and larvae and stops their cycle of converting into adult fleas. Over a few weeks to even a couple of months, Sentinel Spectrum clears the home environment and prevents your pet dog from further parasitic infections.
7. Can my Dog Still Get Fleas with Sentinel?
Answer
Sentinel Spectrum cannot create an invisible shield around your pet that can prevent fleas. There are situations where your pet accidentally gets in contact with another flea-infected dog or area and can also get infected with fleas. However, if your pet dog is getting regularly medicated with Sentinel, then these adult fleas will not be able to reproduce further.
8. Can my Dog take Sentinel and Nexgard at the Same Time?
Answer
Yes, and it’s a good combination. Sentinel cannot kill adult fleas, while NexGard is effective against ticks and fleas. On the other hand, Sentinel gives protection from heartworm, whipworm, hookworm, and roundworm while also preventing the reproduction cycle of fleas.
9. Can a Dog Get Worms on Sentinel?
Answer
No, your pet dog cannot get worms if on regular Sentinel medication. Sentinel Spectrum is an effective deworming medicine developed by Novartis. It is the most preferred medicine that treats and prevents hookworms, roundworms, whipworms, and tapeworms. The effective ingredients of Sentinel also eliminate the microfilariae found in the blood, which prevents any heartworm-related diseases. Only one dose of Sentinel Spectrum is good enough to kill all types of worms and infections.
10. How do I know if Sentinel Spectrum Chewables have expired?
Answer
To check if they have expired, you should first look for the expiration date on the packaging, which should be clearly labeled with the month and year the medication will expire. If the packaging has been discarded, you can check the tablets themselves for a stamped or imprinted date on one side or edge of the tablet. Additionally, you can inspect the tablets for any discoloration or changes in texture, as expired tablets may change in appearance.

Answer

Answer

Tip:

When administering Sentinel Spectrum Chews to your dog, try wrapping the chew in a small piece of your dog’s favorite treat, like cheese or peanut butter.

4. Is Sentinel Spectrum Good for Dogs?
Answer
If your dog is facing parasite-related issues, then Sentinel Spectrum can be of good help for its prevention. It prevents fleas reproduction and is potent against heartworms in dogs.
