I am pretty surprised about the requests you received

and I believe you were right in claryfing this point.
...
but...
this is the first time I hear about a "maximum" high for this breed (even though you say that higher dogs are "
tolerated")
Where does it come from the idea that the typical height is 65-70 for males and 60-65 for females?
Is there any document by any Club stating that?
Or it is just your personal opinion? Or the opinion of some others?
I am asking this because some Judges in Italy write "too big" in some tall dogs judgements, and since now I thought it was a completely wrong thing.
