Cheesy's Links
Kaz has a special connection with Cheesy, him being the pup that Kaz specially picked out for himself. Cheesy is Kaz's adopted son, and he would literally die for the fluffy ball of fur and cheese. They're very close, in the aspect that he raised Cheesy from a baby and nothing that would ever happen could cause Kaz not to love his son.
Avalon loves his brother a lot. Cheesy and Avalon are biological brothers despite not looking similar at all, and were adopted together by Kaz and Limo. He knows he can always go to his brother for anything, even things he can never tell his parents, just sibling secrets and he knows that he can trust Cheesy with his life.
