Bears and dogs share a common ancestor.
For that matter, Homo sapiens and E. coli share a common ancestor. Of course, that was considerably longer ago (2.5 billion years, give or take). Bear/dog divergence was only about 45 million.
There’s a great app here that will calculate the time of divergence for any two species. I’ve found a few gaps, but the coverage is reasonably complete.
