Terribly sorry. I misunderstood your post. For some reason I thought it was a puppy. Forgive me.
I'd say perhaps there could have been damage, perhaps trachea damage from a choke chain or something, collar jerking, etc. You might want to take the dog to your vet and see if they can do x-rays or something to determine if there is some damage there and if so, how extensive. If for no other reason than to ease your mind, if nothing can be done about what has happened.
Again, my apologies for misreading your post.
