HULK’s great-great grandmother Maia is the OG of dog breeders Dark Dynasty K9s, the pitbull who started it all. Acquired by DDK9s founder Marlon Grennan as a 10-week-old puppy, Maia - whose name means ‘female warrior' - has produced generations of the finest protection pups. But the 12-year-old was diagnosed with terminal cancer a year ago, and now DDK owners Marlon and Lisa face an impossible decision as they decide whether or not the time has come to say goodbye to their beloved matriarch. The story is featured in the new season of Barcroft TV’s hit online show Dog Dynasty, which has racked up more than 150 million views on YouTube and Facebook. The show follows the fortunes of Hulk and the other DDK9 protection dogs, which sell for between $5000 and $25,000 and has catapulted Hulk to global superstardom, with the loveable giant having his own dog food brand and merchandise line.
