To confirm the inference that different dog breeds are actually the same species, the most relevant information needed would be similarities in DNA.

Explanation: While physical characteristics can vary widely among dog breeds, DNA analysis can show genetic similarities that prove they belong to the same species. This genetic information is critical in distinguishing species from each other, as it reflects the evolutionary relationships and shared ancestry that may not be evident from physical traits alone.
