They're all so pretty. I just adore little Gia and her beautiful face and coat.
I feel you on the hawk situation. We had a bad scare a few years ago with Poppet and Boo. They were standing right next to my neighbor as he worked on his car, and two hawks circled as low as human height right on top of them. I screamed my head off and came running. I honest-to-God would have never thought of dogs being hawk prey prior to this incident. In fact, my vet didn't believe me when I told him. It wasn't until a lady with a similar story came in with her pom to get the puncture marks treated (hers was actually taken into the air a bit before the hawk dropped it) that he apologized and believed me. What's worse is that they were willing to take the plunge right there was a human not more than four feet away. Scary.
Luckily for me, the area I live in has little to no trees, so spotting one is fairly easy and they can't lie in wait. Still...there's a danger of it, especially with my smaller ones. Gosh, Tilly could actually be stalked and killed by a regular ole cat, she's so dainty and small. I can't imagine having four little, little ones to oversee and protect.
Try looking for hawk deterrents. I've been browsing the chicken boards (who have the most run-ins with hawks) and they've mentioned some interesting, safe, and legal methods to deter these winged harbingers of death.
Bird bombs, statues of a great horned owl (preferrably one with glittering eyes that give the impression it's alive and there's movement coming from it), calling in state falconers to relocate, and temporarily placing carpeting with nails driven through to the underside of limbs to prevent landings are some of the ideas being bandied about.
