I’m going to throw a little non-information into this as my memory is poor at the moment. One of the Border Collie groups I follow has had a discussion going about a topical flea treatment, but I can’t remember the name… not sure if it was Nexgard. It’s something you add to a special collar… anyway, the BC’s are having trouble with it as it makes them lethargic and they refuse to eat. This probably doesn’t help you.
