Meet the new dogs sniffing out invasive mussels at Alberta inspection sites

Alberta's Conservation Canine Unit has two new members. The dogs are part of a larger team working to keep invasive mussels out of Alberta. As CBC's Chelsey Mutter explains, the province says some invasive mussel species have been spreading through parts of Canada since they were first discovered in the '80s.
