Here's Ripley in her Four Paws car harness. Sara asked if she rides well. Shockingly, she does. She spazzes about everything else, but she's happy to put on her safety harness and go for a ride. There's enough slack that she can stand, sit, or put her head out the window, but if I hit the brakes it locks her to the seat.
After elderly Samantha took a tumble off of the seat, and after Ripley tried to drive a couple of times, I decided it was best to buckle them in. The car harness keeps them secure and out of trouble and it keeps me from getting hit with a canine cannonball in an accident. I like this harness because it's heavily padded and easy to fasten. The seatbelt just slides through the back of it and clicks normally into the seat.
Does anybody else buckle up their dogs?
