In PvP this talent can greatly increase a pet's chance of running down an enemy that is attempting to escape if Dash is on cooldown or your pet lacks that skill all together.
Excellent skill for aiding allies in PvP or a Instance where you can quickly send your pet over to assist them.
It's one talent point, it wouldn't hurt any build to reduce time between your pet running to it doing damage.
In Arena should an enemy attempt to escape, this ability can allow them to be run down and stunned by Intimidation if you are specced correctly.

This buff only works outside, and will at times not function when leaving indoors locations.
If you are lagging badly due to poor connection, your pet will seem to not receive this benefit at all.
Does not stack with any other speed increasing effects.

/ Patch 3.0.2 (14-Oct-2008): Removed from Beast Mastery Hunter tree and made into a pet talent. Renamed Boar's Speed.
