Is there any such thing? My three-month-old GSD, Piper, has major itchies from the mosquitos going after her. We have a very low, barely tidal "creek" (basically standing) as the border for our backyard but no other nearby standing water. I spray myself with Off anytime I go outside, but can't do that for her, right?
When we had dog classes at the park, we used Off on all, humans and dogs, approved by our vets, some that were also training with us.
Our dogs in training at that time were a dobie and toy poodle, but there were all breeds in our classes.
