Dr. John Reeve-Newson graduated from the Ontario Veterinary College in 1964.

After graduation, John practiced in Chicago for two years then returned to Toronto and established The Animal Clinics One and Two, where he is still in active practice.

With Dr. Richard Meen, they established Kishniga Kennels in 1971. In partnership, they have bred group and BIS winning Dobermans, Old English Sheepdogs, Skye Terriers, French Bulldogs, Borzoi and Harriers. They have also owned and exhibited group and BIS winning Lakeland Terriers, Norwich Terriers, Standard Poodles, Scottish Deerhounds, American Foxhounds and Whippets.

In 1977 Kishniga's Desert Song, a Borzoi, bred by Drs. Reeve-Newson and Meen and shown by Dr. Meen was Canada's top dog all breeds. The following year "Moustache" as he was called was exhibited in the USA and was number two hound in the USA. He is still the record holder for the breed with forty-seven all breed BIS in Canada and the USA to his credit. His brother "Dalgarth" was the youngest of his breed to win a BIS, which he did at nine months of age. Dalgarth was later owned and exhibited by Dyanne Roth of California. His American BIS total was twenty-nine. The brothers are still among the top fifty winning hounds in the history of the AKC. In 1985, a grandson of Desert Song went BIS at the World Show held in Mexico City.
