Fleas and ticks are more than just irritating pests—they can spread dangerous diseases that impact your dog’s health. If you’re raising a large breed, you already know that their size and lifestyle make them more vulnerable to infestations. That’s where Nexgard Chewables for large dogs come in, offering reliable, easy-to-administer protection.

What is Nexgard?

Nexgard is a beef-flavored chewable tablet designed to kill fleas and ticks. It contains Afoxolaner, an ingredient that disrupts the parasites’ nervous system, causing quick elimination. Developed by Boehringer Ingelheim, Nexgard has become one of the most trusted flea and tick preventives worldwide.

Why Choose Nexgard for Large Dogs?

Large dogs, such as Golden Retrievers, German Shepherds, and Rottweilers, need tailored protection because of their weight and exposure risks. Nexgard comes in chewable doses made specifically for different weight ranges, ensuring your big pup gets the right protection without the hassle of messy topical solutions.

How ...
... Nexgard Works

Once ingested, Nexgard is absorbed into your dog’s bloodstream. When fleas or ticks bite, they ingest the active ingredient, which attacks their nervous system and kills them quickly.

Fleas – start dying within 4 hours.

Ticks – eliminated within 48 hours of attachment.

Dosage Guidelines for Large Dogs

For dogs weighing 25–50 kg (55–110 lbs), Nexgard provides the correct strength chewable. Never split or mix doses. Always stick to one chew per month to maintain consistent protection.

How to Give Nexgard Chewables

Offer the chew as a treat—most dogs love the beefy flavor.

If your dog resists, hide it in food.

Ensure the full chew is swallowed.

Give the chew on the same date each month.

Key Benefits of Nexgard Chewables

Kills fleas fast before they lay eggs.

Protects against ticks including black-legged ticks, American dog ticks, and Lone Star ticks.

Convenient monthly dose with no messy application.

Palatable flavor most dogs accept easily.

Nexgard Safety Information

Nexgard is FDA-approved and proven safe in studies. Most dogs tolerate it well, but mild side effects may occur such as vomiting, diarrhea, or loss of appetite. Dogs with seizure histories should only use Nexgard under veterinary supervision.

Who Should Avoid Nexgard?

Dogs under 8 weeks old or weighing less than 4 lbs.

Pregnant, breeding, or lactating dogs (safety not yet confirmed).

Dogs with severe health conditions should consult a vet first.

Nexgard vs. Other Flea & Tick Treatments

Chewables vs. Topicals – Nexgard is cleaner and stress-free compared to messy spot-ons.

Nexgard vs. Bravecto – Bravecto lasts 12 weeks, while Nexgard provides monthly flexibility.

Nexgard vs. Simparica – Both effective; some owners prefer Nexgard’s taste and proven track record.

Can Nexgard Be Combined with Other Treatments?

Yes, Nexgard is commonly used alongside heartworm preventives like Heartgard. However, never start combinations without consulting your vet to avoid drug interactions.

How Long Does Nexgard Last?

One chew provides 30 days of continuous protection. If you miss a dose, give it as soon as possible and resume your monthly schedule. Delays may leave your dog unprotected.

Tips to Maximize Effectiveness

Stick to the same dosing date every month.

Keep your dog’s bedding and surroundings clean.

Regularly groom and check your dog’s coat.

Use yard treatments if ticks are common in your area.

Common Myths About Nexgard

“It’s unsafe for large dogs.” – False; it’s designed for all weight ranges.
