For those of you that ahve small dogs, how do you restrain them in the car? And do you think whatever you use would work for a 4-pound 3-legged dog? Right now I have a crate that I buckle into the front seat, but it's a pain. I have to take it out all the freaking time, and when it's in it's not easy to get to the door because it's a little too big. I could go with a smaller crate, but I think I'd rather have something that isn't a crate. For Gavroche and Logan I use seatbelt harnesses. Do you think there is one available that would work for such a small dog with only one front leg? I'm just trying to get ideas. It'll still be a couple weeks at least before he can comfortably wear a harness, but that gives me timw to find and order one. I've seen dog car seats too - are those any good? Safe? Easy to use?
