Material and methods
The study was carried out on a group of 15 bush dogs kept at Kolmården Wildlife Park. The group consisted of a parent pair and their offspring.
Food preference test
The first test was a simple choice test with two alternatives. Four different food items (meat, fish, vegetables and fruit) were presented to test which food item the bush dogs preferred i.e. consumed first.
Maximum price paid test
The second test was a lift-door experiment which measured how much the bush dogs were willing to pay (the maximum price paid) to get access to meat. The meat was placed in the box and then the bush dogs entered the box by pushing a hinged diagonal gate loaded with weights inside the smaller box in the upper right corner.
