My husband and I bought what we thought was a mini Schnzauer, but at just about 4 months old, he's already just over 13 pounds. We're assuming that he is not, in fact, a mini Schnauzer, but a standard, however we are not sure. Does anyone know where I can find a size chart for a standard, or for a mini. It doesn't really matter, he's too cute not to keep, we'd just like to know. Thanks
