Our dogs are all on preventative stuff for fleas/ticks but we had a litter of Aussie pups last Summer and a couple of them got a tick (they were not on the preventative yet). I googled the best way to get it off and found this....
How to remove a tick
There are comments below the article about pros and cons to this method but I'll say that it was much more preferrable to me AND the puppies to do it this way. I know a lot of people don't like touching the tick with their finger but I'm not queasy that way. Good luck!!
P.S. You'll get lots of advise about the best way. Just use your best judgement.
