A well chook I wouldn't think twice about but we're not talking an hour or 2. We're talking pretty much a full day excursion ~ a lot of it in heat or wind. I know it's a risk waiting but I have to weigh that against everything else. I don't just stick her in the car for a 1/2 hour drive. She's in & out of cars, bumpy boat rides [our weather is rather wild just now], hiked along a hot road to where we park our car, & she's really, really fragile. So yeah...You might choose differently & if she gets worse so might I but for now...
