What This Medication Is Used For
NexGard Spectra Small is a prescription chewable tablet prescribed by veterinarians to help protect dogs from several common parasites. It is used for flea and tick control, heartworm disease prevention, and the treatment or control of certain intestinal worms.
Parasites addressed
Fleas
Ticks
Heartworm disease (prevention)
Selected intestinal parasites, including roundworms and hookworms
Situations where treatment may be recommended
Ongoing scratching, licking, or skin irritation related to fleas
Risk of tick exposure due to outdoor activity or travel
Preventive parasite care based on local prevalence and lifestyle
Why a veterinarian may choose this option
When a dog requires both external and internal parasite coverage
When a once-monthly oral medication supports consistent prevention
When parasite control must align with the dog’s size, health, and routine
How It Works
This medication contains two active components that work in different ways. One component eliminates fleas and ticks, while the other prevents heartworm larvae from developing and helps control certain intestinal worms.
NexGard Spectra Small works systemically and does not remove parasites from the home or yard. In cases of active infestations, veterinarians may recommend additional environmental control strategies.
How it compares to other parasite medications
Some products focus on a single type of parasite. NexGard Spectra combines multiple protective actions into one chewable tablet, when your veterinarian determines combined coverage is appropriate.
Use as part of a prevention plan
Parasite prevention may change over time depending on risk factors, testing results, and seasonal exposure. Your veterinarian can reassess and adjust treatment as needed.
Dosage and Strength Information
Dosage and administration are determined by your veterinarian. Always follow veterinary instructions and do not modify dosing without professional guidance.
What this strength is generally prescribed for
The Small (yellow) strength, 9 mg/45 mg, is commonly prescribed for smaller dogs when a mid-range dose is needed to support accurate and effective parasite prevention.
