Q: What happens if I miss a dose?

A: Administer NexGard Spectra as soon as you remember and continue monthly treatment from that new date. Missing doses may leave your dog vulnerable to parasite infection.

Waiting Until You See Fleas

One of the biggest mistakes dog owners make is only treating their dog after they notice fleas. By the time fleas are visible, eggs and larvae may already be developing throughout your home. Regular monthly treatment helps prevent infestations before they become established, reducing discomfort for your dog and making flea control much easier.

Missing Monthly Doses

NexGard Spectra is designed to provide approximately one month of protection. Missing or delaying a dose can leave your dog vulnerable to fleas, ticks and intestinal worms, allowing parasites to re-establish before the next treatment is given.

Setting a monthly reminder or enrolling in an automatic subscription can help ensure your dog stays protected year-round.

Choosing the Wrong Weight Range

Every NexGard Spectra chew is formulated for a specific weight range. Giving a chew intended for a smaller dog may not provide adequate protection, while using the wrong size is not recommended by the manufacturer.

Weigh your dog regularly—particularly puppies and young dogs that are still growing—and always choose the correct pack for their current weight.

Assuming Indoor Dogs Don't Need Protection

Many owners believe indoor dogs cannot get fleas. In reality, fleas can be brought inside on clothing, footwear, visiting pets or wildlife. Even dogs that spend most of their time indoors can be exposed, which is why year-round flea prevention is still recommended for many households.

Forgetting About Worm Protection

Some flea treatments only protect against external parasites, meaning owners still need to administer a separate worming product.

Because NexGard Spectra combines flea, tick and intestinal worm protection into a single monthly chew, it helps simplify your dog's parasite prevention routine and reduces the risk of forgetting one part of their protection.

Only Treating One Dog

If you have multiple dogs, treating only one can allow parasites to continue circulating between pets. For the best results, every dog in the household should receive an appropriate parasite treatment according to their age, weight and individual needs.

If you also own cats, they should be treated with a cat-specific parasite product, as dog treatments should never be used on cats unless specifically stated on the label.

Stopping Treatment During Winter

While flea activity often increases during warmer months, fleas can survive indoors throughout winter where homes provide warmth and shelter. Pausing treatment during cooler months may allow flea populations to rebuild unnoticed, leading to larger infestations when temperatures rise again.

Maintaining regular protection throughout the year helps keep parasite populations under control.

Forgetting Puppies Grow Quickly

Puppies can move through weight ranges surprisingly fast during their first year. A chew that was appropriate a month ago may no longer provide the correct dose as your puppy grows.

Checking your puppy's weight before each treatment helps ensure they continue receiving the correct level of protection.

Protecting Your Dog Is Easier With A Routine

Parasite prevention is most effective when it becomes part of your regular monthly routine. Giving NexGard Spectra on the same date each month helps maintain continuous protection against fleas, ticks and common intestinal worms, reducing the risk of missed doses and helping keep your dog healthy all year round.
