Toronto's DNA My Dog firm reported humans with dog DNA in cheek swabs, prompting accuracy concerns.

Toronto's DNA My Dog company claimed two humans had dog DNA in their cheek swabs, raising questions over the accuracy of its tests. The company had previously reported a New Hampshire woman as 28% bulldog, 40% border collie, and 32% cane corso after an informal experiment. Broadcaster WBZ-TV sent samples from one of its reporters to multiple companies, including DNA My Dog, to investigate further.
