I wouldn't expect a 7 month old to shed this fall. Probably not until next spring. My 9 month old is still coming into coat. Izzy has just started to blow coat, and she is 15 months old.
The harshness of the coat texture changes when the dog is altered. It gets more length, and a lot less undercoat.
Also, putting a dog under general anestheia for a procedure, can cause them to blow coat prematurely. We take that into consideration for show schedules with elective procedures, ie. OFA xrays, dental cleanings.
