Even muscle-bound Jose Canseco needs a supposed service dog. The former MLB slugger was spotted Saturday lounging in a cabana at Bare Pool at the Mirage Vegas with his Weimaraner, Bruce, and a sexy brunette. Dogs are not permitted in the pool area, but Bruce is allegedly “an emotional service pet” for Canseco, said a source, and had an ID badge on its collar. According to spies, he “made sure the pooch was taken better care of than him.” Waitresses were seen filling Bruce’s bowl and bringing him wet towels.
