I'd like to make a quick post on how I recommend spending your Gorilla's Talent points. The gorilla is a great pet for leveling, and how you spend his talent points will make a big difference as to how effective he is. Remember, he is a tanking pet!
When you first get a gorilla, he'll already have some talent points to spend:
Please note that I may be off on what levels you can spend points, please adjust accordingly. This does NOT take into account the extra 4 points you'll have to spend if you have Beast Mastery... so spend those points when you get them!
3/3 Great Stamina
2/2 Blood of the Rhino
1/1 Charge
1/1 Thunderstomp (This is the point where your gorilla will become your main pet! This is an awesome ability)
2/2 Natural Armor
2/2 Guard Dog (great for the added aggro and happiness bonus)
3/3 Spiked Collar
2/2 Pet Barding
2/2 Silverback
Good luck out there!
