Eeek! We saw a great horned owl in our trees once. Hawks of all sizes are daily visitors, along with vultures, including the kind that kill their prey. We've had them stalk us on walks. It is unnerving and one of the reasons we cannot enjoy our backyard off leash.
Rather than try to pad train (unless you want to for inclement weather too) I would do short leash walks in the yard.
Stay safe!
