No probs Mate just pointed out that there is some usefull info there.
We use a coller from Greenhound GmbH Cy´s had it on for round a month now and no Tics.
I´m sorry that the link is in German but I´ve looked and not found it in English (yet)
While on exercise in Belize, I woke up one morning to an irritating itch in my bollocks. On lowering my pants, I found a tick attatched to my ballbag, gorging itself on my blood. I got rid of it by twisting it anti-clockwise.
Back at Airport Camp, we found a tick, and one lad who had been plagued by them stopped us from squashing it so tha the could really make it suffer by burning it with a cigarette.
