Sorry, but "species" is biologically defined (check your high school or
college biology books).
Dogs are all in one species because their offspring are fertile.
Physical difficulties notwithstanding - if you (ahem) gathered sperm
from a St. Bernard and artificially inseminated a Chihuahua in heat,
you would get offspring which were themselves fertile.
