Knockout Licensing has appointed four new sub-agents for social media canine celebrity Boo–The World’s Cutest Dog in Japan, Italy, Brazil and Turkey.

Tact Communications will represent the brand in Japan, Lucci Brand Extension & Licensing in Italy, Fama Licensing in Brazil and Istanbul Lisans in Turkey.

The four new agents join three previously appointed international sub-agents that include Caroline Mickler in the U.K. and Eire, the Grahame Allan Company in Australia and New Zealand and M.J.A. Licensing in France.

“Social media is a tremendously effective platform for building a property’s popularity around the world, relatively quickly,” says Tamra Knepfer, co-president, Knockout. “Given the success of Boo here in the U.S. and with so many fans in international markets, the time was right to continue to expand Boo globally, working with wonderful agents on the ground in key markets. After all, Boo isn’t just an American phenomenon–he is the world’s cutest dog.”
