I am not sure if this should be here or in general...but this last week I have found 2 ticks on my dog.

I never have had to use any products on him for fleas or ticks....I am wondering if others know of any safe NATURAL ways to prevent them? I know how to remove them and not leave any tick in ...I hate to give up our walks and runs but I think that is where he is getting them...ick help and thanks
