That's likely as far from your dog as you'll be able to aim. It's not going to be a static target, and if by chance you did hit your dog, it's got the best chance of survival from any of the rounds previously recomended.
I agree. I was going to say aan old ruger 10/22. Although if I had a coyote latched onto my vizsla I think my steel toed work boots would be the best option. I would have a hard time opening fire on anything that is attached to my dog. Plus once the coyote retreats you could have up to 30 rounds in the mag and reach out and touch em!
