City dog licensing records show that more cocker spaniels are registered to addresses in the Flynn Heights neighborhood than to addresses in all other neighborhoods combined. So if an animal control officer finds a stray cocker spaniel anywhere near Flynn Heights, it is likely that the dog belongs to someone in Flynn Heights.
The statement 'whether the city's animal control officers find more stray dogs in and around Flynn Heights than in any other part of the city' would be most useful to know in order to evaluate the argument.
