Vargr are derived from Terran canids, presumably the Dire Wolf or similar creature. Terran canids typically have a fairly wide range of food tastes, including vegetable food. While some vegetable foods are poisonous to canids, chocolate being a good example, the Vargr depicted in the video is clearly an adult, and is capable of making its own decisions about what to eat. If it likes pineapple, the pineapple does not pose a danger to it. Given that the Vargr had to be placed on planets that the Ancients had to terraform for them, they should have relatively robust digestive systems. Mention has been made is several official sources as to the problems the Vilani had in surviving on a planet that was less than adequately terraformed for them.
