The 25 spec Ice pet hits for more damage than the 32 spec ice pet, which hits for more damage than the 40 spec ice pet.
I'm presently level 42.5. My spec during this test is Ice-40.
Using the Training Dummy Level 50 targets outside Castle Sauvage, sending one pet only on a target at a time...
25 Spec Pet: Has a damage range from about 61-97
32 Spec Pet: Has a damage range from about 52-85
40 Spec Pet: Has a damage range from about 49-77
I see this same reduced damage on mobs each time I got a new pet and compared it to the Spec-25 pet. All prior pets scale up through to the Spec-25 pet.
