With an upper weight estimate exceeding seven hundred and seventy kilograms, Pseudocyon was one of the largest of the bear dogs, quite probably even bigger than the largest known specimen of Amphicyon which was estimated to come from a six hundred kilogram individual. Additionally Pseudocyon also had a similar geographic distribution to Amphicyon although Pseudocyon does seem to have lived for slightly longer during the Miocene.
