Gemma McLaughlin and her border collie-Labrador cross Biscuit took part in the study.
"It was great to see the turnout and be part of such a big study," she said.
"It is something that may have some fascinating insights. I was interested in his [Biscuit's] behaviour.
"He is a cross breed so it would be interesting to see which of the breeds is more prevalent in his behaviour."
Director of Genetics Otago Professor Peter Dearden said he was impressed with the turnout.
"There were around 30 dogs of all shapes, sizes and colour. They were all incredibly well behaved and it's great to see people genuinely interested in the genetics of dogs and what they can learn from it."
The testing took place as part of a Genetics Society of Australasia conference held in Otago from July 2 to 6.
The hosting of the conference was a testament to Otago's "great strength" in genetics research, Dearden said.
"There are a good number of geneticists coming to the event, it shows we are doing great things here in Dunedin and people from around the world want to see what we are doing."
