How to Give Simparica
- Weigh your dog and confirm they fall within the 40.1 to 60kg range before administering the Red pack. For dogs over 60kg, use the appropriate combination of tablets and consult your veterinarian.
- Give one chew monthly with or without food - most extra large dogs take it straight from the hand like a treat.
- For fussier dogs, pop the chew inside a small amount of food or place it directly into their mouth.
- Repeat every month year-round for continuous protection - there is no need to wait for tick season.
- Missed a dose? Give it as soon as you remember and continue the regular monthly schedule from that point.

Frequently Asked Questions
Is the Red pack right for my extra large dog? +
The Red pack is designed for extra large dogs weighing between 40.1 and 60kg. This covers some of Australia's biggest and most beloved breeds including Great Danes, Rottweilers, Bernese Mountain Dogs, Saint Bernards, Mastiffs, Irish Wolfhounds and larger Labradors and German Shepherds. Always weigh your dog before purchasing - body weight in giant breeds can vary considerably. For dogs weighing over 60kg, the appropriate combination of Simparica tablets should be used - speak with your veterinarian for guidance on the correct dosing approach.
How quickly does Simparica start working? +
Once your extra large dog eats the chew, sarolaner enters the bloodstream within 30 minutes and starts killing fleas within 4 hours and ticks within 8 hours. Extra large dogs who cover more ground on walks and adventures are often exposed to a greater tick burden, so the fast onset of action after each monthly dose provides important peace of mind for owners of big, active dogs.
Does Simparica protect against paralysis ticks? +
Yes. Simparica provides treatment and control of all three key Australian ticks - paralysis tick (Ixodes holocyclus), brown dog tick (Rhipicephalus sanguineus) and bush tick (Haemaphysalis longicornis). While larger dogs may tolerate tick paralysis slightly differently to smaller breeds, paralysis tick remains a serious and potentially fatal risk for dogs of all sizes. Simparica starts killing paralysis ticks within 8 hours and consistent year-round monthly dosing provides continuous protection.
Will my extra large dog eat the chew? +
The liver-flavoured Simparica chew is palatable and most extra large dogs take it eagerly as a treat. In fact for many big dogs the chew barely touches the sides. For any dog that is cautious about new things, the chew can be concealed in food or placed directly into the mouth. It can be given with or without food so there is complete flexibility in how you offer it.
My dog weighs over 60kg - what should I do? +
For dogs weighing over 60kg, the appropriate combination of whole Simparica tablets should be used to achieve the correct dose. For example, a dog weighing 65kg could be given one Red pack chew (120mg) plus one Green pack chew (80mg) to reach a total of 200mg - however the specific combination should always be confirmed with your veterinarian before administering to ensure the correct dose for your individual dog's weight.
Can Simparica be used with other medications? +
Simparica is generally well tolerated alongside other medications. Extra large and giant breeds are often on joint supplements, anti-inflammatory medications or other treatments given their predisposition to conditions like hip dysplasia and osteoarthritis. If your dog is currently receiving any other treatments or supplements, check with your veterinarian before starting Simparica to make sure there are no concerns specific to your dog.
What if I miss a dose? +
Give Simparica as soon as you remember and then resume the regular monthly schedule from that point. Each dose provides up to 35 days of protection so there is a small buffer built in. For extra large dogs that spend significant time outdoors, year-round monthly dosing without gaps is strongly recommended for continuous tick and flea protection. A free monthly reminder is available at zoetis.com.au/pet-reminders.
Are there any side effects? +
Simparica has a strong safety record and is recommended by veterinarians across Australia. Side effects are uncommon but the most frequently reported include vomiting, diarrhoea and lethargy. In very rare cases, seizures have been observed. Some giant and extra large breeds can have a predisposition to neurological sensitivities, which is worth mentioning to your veterinarian when discussing Simparica. If you notice anything unusual after dosing your dog, contact your veterinarian promptly or call the Zoetis support line on 1800 814 883.
How do I check my extra large dog for fleas and ticks? +
Extra large dogs with thick, dense or double coats can be harder to check thoroughly for ticks and fleas. Run your fingers slowly through the coat against the direction of hair growth, paying particular attention to the head, neck, ears, between toes, armpits and groin - common attachment sites for ticks. Signs of fleas include persistent scratching, biting at the skin, hair loss and flea dirt in the coat. Simparica's monthly protection means fewer ticks and fleas make it past the first 8 hours and 4 hours respectively, significantly reducing the risk of an undetected attachment causing harm.
Please note: Always read the label and follow directions for use. Suitable for dogs and puppies from 8 weeks of age weighing at least 1.3kg. Not suitable for cats or other animals. Not evaluated for use in pregnant, lactating or breeding dogs - consult your veterinarian if applicable. For dogs over 60kg use the appropriate combination of whole tablets - consult your veterinarian. Store below 30°C away from direct sunlight and out of reach of children and animals.
