Tamed pets losing stats even when they don't lose levels

So has anyone else noticed this Phenom?
I deliberately went after a Brown Marmot, not what I was originally intent on taming, when I noticed it was sporting a whopping 225 speed in the tooltip when I moused over it.
I immediately brought it up in the pet journal, it was still the same level, and strength, but the speed had been nerfed down to 117.
What in the name of a half grown rat eating sludge bucket is going on?

Curious as to when you moused over it and saw the 225 speed. If it was during the battle, possible the Marmot had used either its Adrenaline Rush or Leap abilities. They briefly increase its speed by up to 100%.
