Two of my dogs are tethered as their primary method of containment. I do twice daily clean ups, in addition to them being let off the chain for exercise, attention, and work.
This year, despite my clean up routine, the worst biting flies are coming around. I hate to see the dogs bothered by them and, until I find a solution, they've had to be in the house. Which is a shame when the weather has been so warm and nice out. I'm a little leery of the human products (Bug Off) and such, because I don't want to spray the dogs with something that could irritate them or cause skin issues. I made a solution out of natural neem oil but it just wasn't effective. I haven't had a fly issue before this season and, according to the vet's office, I'm not the only one seeing these pests.
Any ideas?
