The pit bull is under quarantine at the Marathon County Humane Society Monday
Cindy Ryder was attacked by the dog as she walked her Chihuahua near downtown last Thursday. Ryder says the pit bull came running out of a house, grabbed her arm and pulled her to the ground as she tried to save her dog, Bartok.
Wausau Police Chief Jeff Hardel says Ryder suffered numerous abrasions, bites, punctures and cuts. Hardel tells WAOW-TV it was a vicious attack and one of the worst he's seen. Hardel says police records show no other incidents involving the dog.
