Thanks for the answers.

I dont want to do a surgery on him, its not often that he limps, maybe 1-4 times in a year, he does not often ''scream'', when he does it its just in 1-5 seconds then he goes back to normal.
Im not sure its pain, I think he's just scared, doesnt know ''what that was''.

I think he has just 1 grade, im not sure, im going back to the vet in 2-4 weeks to buy dog food, I'm going to ask the vet what grade he has then.
