Who are the two animals that White Fang meets when he arrives at Scott’s family’s home? Describe them and what happens between them.

He is immediately met by an angry sheep dog named Collie. Because the dog is female, he will not attack her; his instinct forbids it. However, she has no such instinctual barrier, and fears White Fang because she knows he comes from the Wild. He is a wolf. She springs upon him, biting his shoulder and not allowing him to go any further. Scott decides to let White Fang deal with Collie himself, and continues the ride. White Fang cannot follow, however, as Collie still won't allow him to pass. He finally just knocks her over.

Running past Collie, he finally reaches the house. A new opponent attacks him, a deerhound named Dick, and White Fang is thrown from his feet. As White Fang is almost about to close on Dick's throat, Collie strikes at White Fang and he is again knocked off his feet. By this time, Scott is next to White Fang, holding him, and the dogs are called off by Weedon's father, Judge Scott.
