Used to use frontline, but it got to costly on four dogs and there is no ticks in AZ. At least not where we hunt and they don' t have any fleas either. I guess the dry hot climate isn' t a good breeding ground for these bugger. Heartworm is a problem and they are all treated for it.

And the dogs are used to heat but I guess they are going to freeze solid in N. Dak. The can' t handle the winter here and have to sleep in the house on the couch.

Thanks for the help.
