mkgwolf, thought you might like this pic of Chetan and Apollo jawsparring. Wolves do this as sort of a "contest"...who can open their mouth wider perhaps??? LOL
These two wolves were youngsters when I was volunteering there(I was there the year they were born!). Chetan is still a part of the main pack, but Apollo has moved to a small pack called the "pillow pack", which is separate from the main pack.
