Dogs have been used for sledding in the Arctic as far back as ~9500 years ago. However, the relationships among the earliest sled dogs, other dog populations, and wolves are unknown. Sinding et al. sequenced an ancient sled dog, 10 modern sled dogs, and an ancient wolf and analyzed their genetic relationships with other modern dogs. This analysis indicates that sled dogs represent an ancient lineage going back at least 9500 years and that wolves bred with the ancestors of sled dogs and precontact American dogs. However, gene flow between sled dogs and wolves likely stopped before ~9500 years ago.

I remember the Greek writer and soldier Xenophon was also a dog breeder. I have no idea what kind of dogs they had back then.

I like dogs.

Inuit will tie a sled dog bitch in heat so a wolf will mate with her. Genetic crossovers still happen.

This is more evidence of the same finding here -
" Regardless, this direct evidence suggests a longer timescale of wolf-dog population history and thus implies that the 11,000 - 16,000 years ago wolf-dog divergence inferred in a previous study should be recalibrated to 27,000–40,000 years ago.
To examine shared ancestry between the ancient Taimyr wolf and a larger set of modern-day dog populations, we used data from 48 dog breeds genotyped at 170,000 SNPs and computed D statistics to assess whether each breed shared more alleles with the Taimyr wolf than a set of 15 modern-day gray wolves . We found clear evidence of a closer relationship between the Taimyr wolf and the Siberian Husky (Z = 4.3, p = 0.000009), Greenland Sledge Dogs (Z = 3.6, p = 0.00016), and, to a lesser extent, Chinese Shar-Pei and Finnish Spitz (p < 0.05) compared to other dog breeds" Ancient Wolf Genome Reveals an Early Divergence of Domestic Dog Ancestors and Admixture into High- Latitude Breeds

Did Percy Sledge own a dog? Was it a Sledge dog?
