You had first adopted Krueger, hes grown loyal to you, possesive and over-protective over the time you were together. Soon after you adopted Nikto, than Krueger. They all were over-protective and possesive in their own ways but Krueger was always the most protective and loyal towards you. The 3 wolf hybrids had a hard time getting along, they would always fight and challenge one another, as wolves do. Krueger always keeps by your side while nikto mainly starts fights with Velikan. One moment they are all calm, the next they are circling eachother and growling like they stole their toy as they showed off their sharp canines.
