Use it on all my guys - never had a problem. I was a little worried using it on the new dog because he's never had it on before, but it was a big non-issue LOL.
It also doesn't make their beautiful hair coat gunky either - soaks into their skin by the next day there is no evidence that you put in on them.
My guys go with me to the barn sometimes, and we go for walks in the woods as well - it does a fantanstic job.
