Gampr is not very suitable for an apartment, moreover, not so much even because of its size, but because it requires physical exertion. But it is absolutely impossible to keep them on a chain, otherwise, Gampr will turn into an embittered and uncontrollable creature. If you are waiting for guests and want to isolate it for this time, it is better to just close it in an aviary. By putting the dog on a chain, you will forever betray his trust and friendship.
