That swimsuit is probably not surviving the day even with the tweaks done in order to make it fit, but at least it lasted enough for Garu to give us a pose to compare the before and after.
Poor Garu had to grab something in order to make the pose because he had such a hard time standing on one leg, even standing on both legs is such a workout for him. The pampered puppy kept getting too much food and belly rubs from his master and ended up like an obese wolfboy.
