As you did not provide any further info we have to assume the dog didn't sustain any type of injury of which you are aware, like for example an injury to the thyroid. The thyroid lies along the trachea and reportedly can be damaged by the old style choke chains. Does the dog have any skin abnormalities, like a dull or dry coat or hair loss?
My heart sank when I read this. We never walked him on a leash much until recently because we moved into the 'burbs. My GSP is very hard headed and I resorted to a choke chain to keep him from pulling me and tripping me. His episoed have never happend befor use of the choke chain. I'm hanging it up for now to see if it makes a difference.
He's in fantastic shape and has no health problems other than this issue. Thank you.
