What Is Capguard for Dogs?

Capguard dosage for dogs is an oral topical flea treatment for dogs, with nitenpyram as the active ingredient, which is available over the counter. It is formulated to work quickly and effectively on killing adult fleas and would be a great choice if treating an active infestation. Once swallowed, Capguard starts to work in 30 minutes, most adult fleas are cleared in a few hours.
Capguard medication for dogs can be used on puppies and dogs 4 weeks of age and older, weighing 2 lbs or more. Available in tablet strengths according to your dog’s weight, appropriate dosing is easy and effective.
Unlike monthly flea preventives, Capguard provides short-term flea control only. Does not destroy flea eggs or larvae and does not help to prevent future infestations. Often a monthly flea preventer is used in conjunction with Capguard as part of a comprehensive flea control program for long-lasting protection.
Capguard Instructions and Warnings

Weigh your dog before administering Capguard dose to ensure proper dosage for safe & effective treatment. The tablet can be given straight to your dog’s mouth or mixed in a bit of food. If it’s given with food, be sure to watch your dog to ensure he eats the whole tablet. If it is not certain if the tablet was swallowed, it is safe to repeat the dose.
For the best results, treat all flea-infested pets in your household at the same time. Fleas can continue to multiply if one pet is not treated, potentially causing continued infestation.
Capguard medication for pets should not be given to dogs under 4 weeks of age or less than 2lbs. Safe when used as directed for pregnant and lactating dogs.
Once given, you might observe increased scratching from your dog. This is a temporary response and is not a reaction to the medicine, but rather to fleas dying off as they’re killed off and is usually self-correcting.
Storage and Safety
The children should not have access to Capguard. Keep the tablets at controlled room temperature (between 15°C and 25°C or 59°F and 77°F). Keep the medication in the original container and avoid excessive heat, moisture and direct sunlight until use to maintain the effectiveness of the medication.
What Happens If You Miss a Dose?
If a dose of Capguard is missed, it can be administered as soon as it is remembered, provided that the dog still has flea infestation. If the next dose is due to occur very soon, the missed dose is ignored and the next dose is given as scheduled. Avoid overdosing and only administer additional doses as a veterinarian may require. Capguard is intended for the rapid control of fleas and not for ongoing prevention, so it’s not as critical as a monthly flea preventive.
Will Capguard Work in Combination With Other Flea Products?
Yes. Since Capguard dosage for animals only kills fleas that are on your dog at the time of application, it is often recommended to be used in combination with a long-term flea prevention product. That will give immediate relief, while monthly flea preventatives will help to prevent future infestations. When using flea treatments, be sure to consult with your veterinarian before using more than one product, particularly if your dog is also treated for other health issues.
