Cure for sheep ticks on dogs - Moss got one last week on Preseli mountains;
Liberally dowse offending tick with alcohol (whiskey), it was over his eye, enormous creature, wait a couple of minutes for the tick legs to relax and then remove with sharp tweezers. The one on the dog dropped off, drunk presumably, and it was a couple of hours before we found it...yuk. Not sure if they get on humans though.
