Pregnant and lactating dogs in New Zealand: parasite control
Introduction
Pregnancy and lactation change a dog’s needs. Keep environments clean, avoid new exposures, and speak with your vet before giving any product. Your clinic will confirm options and timing for your dog’s weight, health and stage.
Before mating
Book a pre breeding check. Confirm current weight, teeth and skin health, and discuss a parasite plan that covers fleas, ticks and worms through pregnancy and nursing. Set reminders now so dose dates do not clash with due dates.
During pregnancy
Focus on the basics you control at home. Keep bedding clean and dry, vacuum high traffic areas and car mats, and avoid long grass or dense scrub where ticks live. Keep other pets on time with their own prevention to reduce household pressure.
After whelping and through lactation
Clean whelping areas daily and wash bedding often. Puppies are sensitive, so avoid unapproved products near them and keep application sites away from curious mouths. Your vet will set a worming plan for the litter and advise on timing for mum.
