Wow Bongo sure is handsome! Hehe sorry no tips nor advice i better leave that to the experts here. Oh but maybe you can try wetting him on walks or giving him ice cubes? You could put the ice cube into those thermobottles. We also wet my boy when i think he doesnt drink enough but is panting too much. Helps cool them down. Thats just what i do though lol. Better wait for the experts though .
