I'm thinking Subaru for my next car--which won't be for a while because apparently Toyotas never die. Anyway, both the Subaru Legacy station wagon and the Forester seem to be popular among my friends with dogs. They're also highly rated by Consumer Reports (the cars, not the friends with dogs LOL). I need a vehicle that will accommodate a rear tow hitch for a bike rack, roof racks for kayaks, and of course, the large chocolatey fellow shown in my avatar, and the Subaru models seem equal to all my requirements.
On the other hand, my neighbor-with-dog just got a Honda CRV and both she and her dog are very happy with it so far.
