However, each medication has a slightly different mechanism of action and may cause different side effects. It’s essential to discuss your dog’s specific needs and medical history with your veterinarian to determine which medication is best for your pet.
Does Sentinel kill fleas and ticks?
Sentinel is effective in controlling flea populations by preventing flea eggs from hatching. However, it does not kill adult fleas or ticks. If your dog is also at risk for tick-borne diseases, you may need to use an additional product for tick control.
How long does Sentinel stay in a dog’s system?
Sentinel is designed to provide protection for 30 days. After this time, the medication’s effects gradually decrease, and your dog will need another dose to maintain protection against heartworms and other parasites.
Can I use Sentinel for dogs with a history of seizures?
There is no strong evidence linking Sentinel to an increased risk of seizures in dogs. However, every dog is different, and it’s important to discuss your pet’s medical history with your veterinarian before starting any new medication.
How soon can I expect to see results after starting Sentinel for my dog?
While Sentinel starts working immediately to prevent heartworms and disrupt the flea life cycle, it may take some time before you notice a significant reduction in fleas. Flea populations can take a few weeks to months to control completely, depending on the severity of the infestation. Be patient and continue administering Sentinel as prescribed, and consult your veterinarian if you have concerns about your dog’s progress.
Can I give Sentinel to my pregnant or nursing dog?
It is essential to consult your veterinarian before administering any medication to pregnant or nursing dogs. Sentinel has not been adequately tested for safety in pregnant or nursing dogs, so your veterinarian will determine if the benefits of using Sentinel outweigh the potential risks in your dog’s specific situation.
Are there any drug interactions I should be aware of when using Sentinel for my dog?
While Sentinel is generally considered safe, it can interact with certain medications, such as theophylline, a drug used to treat respiratory issues. If your dog is taking any other medications, be sure to inform your veterinarian before starting Sentinel treatment to avoid potential drug interactions.
What should I do if my dog misses a dose of Sentinel?
If you forget to give your dog a dose of Sentinel, administer the missed dose as soon as you remember. If it is close to the time for the next scheduled dose, skip the missed dose and resume the regular dosing schedule. Do not give your dog two doses at once. To avoid missing doses in the future, consider setting reminders or using a calendar to help you stay on track.
Can Sentinel be used in puppies?
Sentinel can be used in puppies as young as four weeks old and weighing at least two pounds. However, always consult your veterinarian before starting any new medication for your puppy, as they can provide specific guidance based on your puppy’s age, weight, and overall health.
How should I store Sentinel for my dog?
To maintain the effectiveness of Sentinel, store it in a cool, dry place at room temperature, away from heat, moisture, and direct sunlight. Keep the medication out of reach of children and pets to prevent accidental ingestion.
How can I ensure my dog takes Sentinel without spitting it out?
Some dogs may be resistant to taking Sentinel, especially if they find the taste unappealing. To help your dog take the medication, try these tips:

- Use a pill dispenser or pill pocket to conceal the medication.
- Crush the tablet and mix it with a small amount of wet food.

Consult your veterinarian for guidance on the best alternative for your dog based on their specific needs and medical history.
