That's good news about your fingers and grip. I hope the straightening and the arm strength will return in time. Have you asked for physical therapy? I understand that when an arm or leg has been in a cast or sling, it needs a little PT to restore its strength.

I think 'the average folkie Mudcatter' understands that in your first post, where you said you hate dogs, you were merely venting. You hurt, you were worried that your playing ability was damaged, you were miserable, you were traumatized, and you needed to let off some steam.

I want to be fair to dogs, but I will never change my opinion that Weimaraner's are any ugly color and have creepy, pale eyes.

One final thought - when you go for a stroll take a stout cane or walking stick along in case you encounter that dog again.
