Here is my Quicklist Guide to the Alliance Side of the Pet Trainer Intro Quests. This is a quick reference to see what type of pets you will need to defeat the trainers easily. On Trainers who have the same type of pet for all 3 pets in their party, I would recommend you bring at least two pets that are the opposite type (i.e. bring three appropriate leveled Mechanical types to fight three trainer Beasts). Don't rely on fighting all three of their pets with just one of yours, despite the fact that they will have stronger attacks and defeat them quicker.

*Author's Note: In writing this guide, I used various references from wowhead and warcraftpets.com. I did not write this guide as I was doing each trainer. Some information might be wrong. Please feel free to comment and I will change it as needed.

He's got 3 spiders, all level 5.
*edit* Apparently they're now level 7. They're beasts, so mechanical would work well against them (or an upside-down glass and a piece of paper).

If you arrive at Eric Davidson and he does not give you the option to battle, simply log out and log back in.

This happened to me on the morning of 11 Oct 2012. I relogged and he was ready to battle. For what it's worth, he lost miserably to my Mini Thor.
