All other windows (even rehauled ones, like character panel or top ranks) have their close buttons in top right corner, square-shaped with a big X in the middle.
Pet training, on the other hand, has a button in the bottom left, rectangular-shaped, with text "Close".
IMO it doesn't make sense, it's counter-intuitive. Don't get me wrong, it's not the matter of "getting used to the new look", it's the matter of consistency in design.
Also, while I'm at it, if you decide to change the button to the corner, there's more space to fill. It can be used to make the "After level 10..." text bigger and more readable, or be a placeholder link button for "Coming Soon-ish" Beast submenu or something like that
Edit: top right* thanks, ND1
