I have received some very useful info about ticks and their treatment over the last few days, and so am posting here to you two of the best.
1. TICKS FOUND ON DOGS in AUSTRALIA
The following ticks have been recorded from dogs-
Ixodes holocyclus (paralysis tick)- Qld to Bairnsdale in Vic, causes paralysis.
Ixodes cornuatus> (indigenous tick)- southeast coastal NSW, central Vic, Tas, may cause paralysis.
Ixodes australiensis (indigenous tick)- WA and Tas.
Ixodes hirsti (cat tick)- may cause paralysis.
Ixodes tasmani (possum tick)- Tas, Vic, NSW, Qld, SA, WA.
Ixodes myrmecobi (indigenous tick)- southwest of WA.
Boophilus microplus (cattle tick)- Qld, NT, WA, northeastern NSW, rare on dogs; transmits the cattle blood parasites Babesia bovis and Babesia bigemina
Haemaphysalis bancrofti (wallaby tick)- coastal Qld and NSW to Nowra, Kangaroo Is (SA).
Haemaphysalis longicornis (scrub tick, bush tick, New Zealand cattle tick)- southern coastal Qld, coastal NSW, northeastern Vic, esp Murray Valley; introduced from Japan.
Rhipicephalus sanguineus (brown dog tick), mainly inland areas of Qld, WA, NSW, Vic, but found mostly in northern parts of Australia. It is a vector for infectious agents affecting dogs such as Babesia canis. Infection with Babesia canis may result in a symptomless carrier state or in disease ranging in severity from mild to severe and occasionally ending in death.
Amblyomma triguttatum queenslandense (ornate wallaby tick)- north Qld.
Amblyomma triguttatum triguttatum (ornate kangaroo tick)- Qld, northern NSW, southwestern WA
Aponomma aurunginans (wombat tick)- southeastern Australia, rare on dogs.
Ornithodoros gurneyi (inornate kangaroo tick)- widely found all States except Vic and Tas; the only "soft" tick commonly recorded on dog.
2. Treatment of Ticks

Sounds like it is about time to give my 2 cents worth on the tick prevention debate. My vet practice is in Avalon, which is TRULY the paralysis tick capital of the world. We are a small one vet practice and we see well over 100 tick cases every year. We see dogs and cats that are on proban, tick collars, pyrethrins and frontline that have ticks.
NOTHING works with 100 % efficiency and all dogs should be checked daily for at least 10 days after being in a tick area. The differences in the products are:The tick collars and proban (and rinses such as malathion or bayer flea and tick rinse, or tiguvon spot on) are organophospates that are highly toxic to all animals and particularly easy to overdose. Chewing a tick collar is enough to cause problems. Some of these problems may be seen later down the line.
NEVER use a combination of two of these products together. NEVER exceed the advised dose. Don't let the kids play with the dogs with tick collars on. They act by causing excessive excitement in the tick's (and all other animal's) nervous system. So, before the tick dies, it often excretes more saliva (and poison) into the dog. Never use these products on a tick before you pull the tick out (and don't use metho, either) because this causes the tick to pump in more poison.
Permoxin is a pyrethrin, and relatively less toxic. It works by paralysing the tick, rather than overexciting the tick. It is a much safer product to use. It is relatively economic and is available as a rinse. It was also available as a spot-on product, although I do not know if that is still made.
Frontline is a new generation product that paralyses the tick. It acts on part of an insect's nervous system not present in mammals (don't ask for the technicalities - am just reporting a drug rep's description) so that it is virtually non-toxic for mammals (EXCEPT RABBITS-never put frontline near a rabbit.) Because it is so safe, you can use it in conjunction with other products such as proban or tick collars. We recommend Frontline. The reason is that, even though we see cases of tick paralysis with pets that have had Frontline applied, it seems that these dogs and cats do not seem to be as severely effected as the others. Probably, because the tick is paralysed, it has not pumped in as much saliva (and toxin). Perhaps I should collect exact data on this to prove (or disprove) my observation. Perhaps, next year-this tick season is nearly over.
My recommendations are:-
1.. Frontline topspot applied every two weeks. If your dog is near the cut-off point in size range, or if the dog is very hairy, then use the next size up.
2.. Use a little extra spray around the neck and face (where 90% of ticks are found). You can spray onto some cotton wool and then wipe around the face.
3.. If finances are tight, use permoxin weekly, instead of frontline
4.. Peak of season, or if in a particularly bad area, use a tick collar as well, but take off when swimming. Use proban instead if collar chewing, or kids wanting to hug the dog is a problem. Do not overdose, and do not use all year round.
5.. If you are doing something and it seems to be working, don't change the system!
6.. There is no substitute for going over your dog every day. Just remember that a dog can get worse up to 48 hours after a tick is removed so if there are any symptoms, get the dog to your vet. Signs can be vague at first, and misleading. Wobbly legs, vomiting or coughing are the most likely. Most dogs, especially if treated as soon as symptoms are seen, will survive a case of tick poisoning, and after a period of convalescence, make a 100% recovery.
Hope you find it useful and informative, and thanks to both these knowledgable people for their research and input!
