Copper loves to go in the car. As soon as I take one of his harness vests out he is jumping around like a maniac. I use a dog car seat. I put his blanket in it and attach the clip to his vest. Since his vaccinations are not totally complete, we have only been to the vet and McDonalds drive through. Ok, I give him bits of hamburger without onion of course...bad mom I guess...
but I wanted him to get used to the car for short trips before we take any long ones.
He was a little anxious the first few times in the car seat, but now he loves it! Good luck with your baby!
