Pitbull Announces November Release For 'Global Warming'

PET SOUNDS: Dog days are just beginning atop the Billboard Hot 100, as Pitbull celebrates his first No. 1 with "Give Me Everything," featuring Ne-Yo, Afrojack and Nayer.

In anticipation of the Miami rapper's ascension to the apex, Chart Beat reader and frequent contributor Pablo Nelson of Berkeley, Calif., looked into "What else? ... artists with animal names that have reached No. 1 on the Hot 100.

"In terms of canine-related artist names that have led the chart," notes Nelson, "Pitbull joins Three Dog Night, Nate Dogg and Snoop Dogg ... and, 'Toto,' too."

With Nelson having doggedly searched each man's best friend to have topped the tally, here is an updated look at a zoo's worth of animal-inspired artists that have clawed their way to the top of the Hot 100 (with leeway allowed for alternate spellings):
