I trained Snarler at 9:35 AM EST on Rexxar.  He arrived near west side of Pavilion after several minutes of grinding.  I abandoned old pet,a longtooth runner, and began taming.  The first attempt to tame failed because he stealthed before process was complete, but he quickly re-appeared and I tried again.  This time he tried to stealth right when tame was completing(flash of light).  The was tamed but I had to re-log to get him to appear under my name as my pet.  I was able to feed him immediately though in spite of glitch. Because of previous pet I already had Snarlers abilities plus Dash 2.  If you dont mind a more plain pet the runner very easy to find as they are very common, lvl 40-41, have an extra ability (Dash 2), and don't stealth making taming process a easier.  So i recommend getting runner first then get Snarler if convenient.  BTW I'm lvl 42 so Snarl will catch up to me quickly :).
