Effective Flea and Tick Prevention
NexGard Chew is a parasite treatment for extra large dogs weighing over 25 kg and up to 50 kg. Afoxolaner acts on the nervous system of fleas and ticks as they feed, killing fleas within 8 hours and ticks within 48 hours.
Easy-to-Administer Chewable Tablets
The chew carries beef braised flavouring, so most dogs take it without a struggle. Each pack contains three chews, which is three monthly doses. Do not give to dogs with a known hypersensitivity to any ingredient.
Dosing Interval and Age
Flea activity lasts at least 5 weeks and tick activity lasts one month, so give one chew a month, on the same date each month. NexGard may be used in dogs from 8 weeks of age weighing at least 2 kg. Match the chew to your dog's current weight.
Safety information
Afoxolaner is a member of the isoxazoline class of medicines.
This class has been associated with neurological reactions including muscle tremor, loss of coordination and seizures. Seizures have been reported in dogs with no previous history of them. Use with caution in dogs with existing epilepsy or a neurological disorder, and tell your vet before use.
This is a prescription-only veterinary medicine. Use under veterinary direction.
How we work out the portion
A pet's daily energy need starts from its resting requirement — 70 multiplied by body weight in kilograms to the power of 0.75 — then multiplied by a factor for species, life stage and activity. The calculator above uses 1.4 to 2.2 for adult dogs and 1.0 to 1.4 for adult cats.
The gram figure then depends on how many calories are in a kilogram of the food. That varies by formula, so we use a sensible default and show it openly rather than hiding it. If the bag states its own kcal/kg, use that number instead.
Choosing a pack size
The price-per-kilo figure next to every size is the honest comparison — a bigger bag is only better value if the maths says so, and on a handful of lines it currently does not. Buy the size your pet will finish within about six weeks of opening, so the food stays fresh.
