If he did say that working ability was more important than appearance, would it change your mind?
Here's some quotes from Max.
"The Shepherd dog is a service dog & must be bred as a service dog AND must only be judged as a service dog. With service dogs, suitability ranks higher than beauty: indeed their real beauty and their only nobility consist in their complete adaptability in the arrangement, balancing and coalescence of each & every part."
"The basis of the judgement must be the service which is demanded of the dog: shy, weak-nerved animals are to be marked as injurious to the breed, even as over-bred dogs (oversize) are not true to breed type. In addition: a good shepherd expression, a lively disposition, a long well-knit body suitably proportioned for service, not spongy or bulky, whose form guarantees a stretching out & swift gait, with powers of endurance are among the first qualifications. In the case of bitches, solidity is preferred to beauty...oversize or bitch-like dogs and the fading of color coat are injurious from the point of view of breeding & are to be marked accordingly. Defects in body-build and gait, teeth, jaw, head, ears, tail, haircoat, general coloring, and eye color may exercise an influence in marking. Short, stumpy tailed dogs, albinos are dismissed as harmful to the breed."
"Exaggeration is bad in all circumstances."
