My puppy a pitty mix 10 months old was in the car and we were going to the vet.I had the windows half way down but i had him on a leash.But he wanted to jump out...well we got there and i got out the car i let go of the leash to get out and go get him.In the mean time he flys out the car window...and hes a big 65 pound dog...i still cant believe he did it
