Long-Acting vs Monthly Parasite Protection for Dogs in NZ

The short answer
Both monthly and long-acting options work well when used on time. Pick the application you can give reliably. Think about swims, trips to the bach, and how often you want application days on your calendar.

Monthly options

• Simparica Trio chewable tablet for dogs
  A simple monthly chew that covers multiple parasites. Give with food and set a phone reminder.

• Nexgard chewables for dogs
  Monthly chew focused on fast-acting flea and tick control. Handy for active dogs and busy homes.

Long-acting options

• Bravecto chew for dogs
  Long-acting flea and tick control in a tasty chew. Fewer application dates across the year.

• Bravecto topical solution for dogs
  Long-acting spot-on if you prefer a skin application. Apply to clean, dry skin and keep the site dry as per the label.

How to choose

• Your routine: Monthly suits people who like regular reminders. Long-acting suits those who prefer fewer dates.

• Swimming and bathing: Chews are popular for river and beach dogs. If you use a spot-on, plan around swim days and drying time.

• Where you go: Bush tracks, farms and long grass raise tick risk. Keep prevention on time and do quick hands-on checks in risk periods.

• Keep it simple: One clear plan you follow all year beats swapping often.

Quick application guide

• Chews: Easy to give with food. Good for swimmers.

• Spot-ons: Apply to skin, let dry fully, and keep the site away from kids and other pets until dry.

Safety basics

• Weigh your dog and choose the correct pack every time.

• Use dog products on dogs only. Never use dog products on cats.

• Do not combine treatments unless your vet advises it.

• Read the label each time and set phone reminders so you do not miss a dose.

• If your dog has a health condition, is pregnant, or takes other medicines, ask your vet first.

FAQ

Is long-acting better than monthly
Neither is better for every dog. Long-acting reduces how often you need to dose. Monthly keeps a steady routine. Both work when used on time.

What if I miss a dose
Give it as soon as you remember, then reset your schedule from that date. Ask your vet if you are unsure about timing.

Can I switch between a chew and a spot-on
Yes. Start the new product when the previous one would have been due to avoid gaps or double dosing.
