Does this apply to mixed-breed pit bulls?

Are exemptions available?
Licensed breeders, dogs medically unfit for surgery with veterinary certification, and competition dogs may obtain intact-dog permits. Owners must apply through SF Animal Care and Control before keeping an intact pit bull.
Seattle FAQ

No. Seattle uses pricing incentives instead of a mandate. Unaltered pets pay roughly 50% more annually for their license but remain legal to own.
How do I qualify for the low-cost spay-neuter clinic?
Show proof of income at or below 200% of federal poverty level. Apply through Seattle Animal Shelter; vouchers cover most of the surgery cost.
