BTW Get a couple chickens if you have a tick issue. They will eat all the bugs in your yard. I raise dogs and I have two chickens and never had a tick problem :)
Do you know if ducks eat them? We have six ducks and I was thinking they'd help with tick control, but they seem to be worse than ever.
A trick about removing ticks that I have heard about, but not tried yet, is to soak a cotton ball with Dawn dishsoap and place it on the tick. Let it sit a few minutes and the tick will back out and will be caught in the soap and you don't have to pull it out. If it works, it may be less traumatic for your dog.
