Replying to Has your dog ever jumped out of the car?

I was driving 4 days ago, my dog was with my dad in the passengers seat and I stuck her head out of the window too far and lost balance, something she's never done out of the hundred times she's been in the car. We were going about 25/30 miles an hour and she fell on her left hind leg. She doesn't put any pressure on it and we've been giving her medication. She's 1 year old and my dad says she didn't break anything and will get better but I think her leg is at least sprained or fractured. Would you say she'll be fine or should I take her to a vet?

Sparknotes: dog jumped out of the window, seems to be healing. Is a vet mandatory?
