Pervis McSlade first appeared in In The Line of Doody. He is the commissioner for the Central Park Zoo. He was making an appearance to announce the opening of the Children's Zoo. Skipper saved him from being hit by a pigeon named Frankie.
He later appears in The Hoboken Surprise to make Frances Alberta the new zookeeper of Central Park. When he finds out Frances was building bio mechanical androids to replace the animals with, he fired her.
Pervis is very arrogant and outspoken, blatantly saying he hates pigeons. Despite this he has the respect of both Skipper and Frances.
