There are several considerations for your pets when you take them interstate.
On mainland Australia, they will meet new-to-them intestinal worms; rampant fleas; paralysis tick; heartworm ....
For your dog a new product, NEXGARD SPECTRUM, given monthly, copes with all of that ! although you may feel they need added help against fleas. Take care. We are here to advise you.
For cats you will still need to combine therapies. Nothing does everything. FRONTLINE PLUS covers ticks and fleas [but not heartworm]; ADVOCATE prevents heartworm, roundworm & fleas [but not ticks nor tapeworm] ... etc ... we can work through what is needed with you and develop a PLAN.
Decisions will be based on where you are gong, how you are travelling, how long you will be away.
Also full C5 or F4 vaccination is encouraged, so you can be ready to put them in kennels if you need to, or meet unexpected demands from airlines.
Safe and secure travel boxes, harnesses, name-tags AND up-to-date Microchip needed?
When you return: keep your pets on Heartworm prevention for at least 3 months to stop any problems developing And your dog will need Praziquantel tapeworm treatment against Hydatids before entering Tasmania.
