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
