German Shorthaired Pointer Q&A
I would say the normal weight would depend on whether you had a male or female, but it should be the average of between 10-15 pounds. The Mini Schnauzer I had weighed in at about 17 pounds full grown.
My Schnauzer is 2 years and is 8 pounds. I love my Marlin and feel that I got lucky when I got him. All my friends have schnauzers and they are at least 12-17 pounds.
