1st- if you have a safari hat, save your pet xp biscuits- they are no real benefit.
It will take 2 battles to level a pet from one to 25 during pet week with a safari hat and no buffs.
2nd
If pure speed is your goal, (which is especially beneficial if you are leveling an alt toon)- I suggest you keep a sharp eye out for the Legion repeatable WQ - Odorrog (snail fight-highmountain)
It is a faster fight, thus levels more pets reliably and cheaply. You'll need bandages, but they are cheap and easy to obtain. The snail fight WQ has not appeared lately so odds are in favor of it popping. We are due to see Sir Galveston soon as well-another fast and effective repeatable WQ.
Once I obtained the draenor pet battle monument for garrison, I've always turned to the better Legion repeatable quests for
pushing alts from 60 to 70. This can make you some gold while leveling alts.(if you peddle leveled pets at all)
If you prefer a garrison social time- have at it-happy gaming to you all

UPDATE
Ironically, Sir Galveston is actually up in Legion Dalaran -Sat. march 4th
It is a 70 second fight
