Took the lab out for her 3rd birthday present to get some feathers in her mouth yesterday at pheasant preserve in Delaware and picked off a few tics on the dog and myself. With the mild winter, I fear a bad tic and flea year is coming. Does anyone use a natural repellant with decent results on your dog? Lots of things on the internet but would appreciate a first hand testimonial from someone here. I use frontline but would prefer not using the commercial stuff if it can be avoided. They seem to have some potential harmful ingredients.
