As of now, pet pal only gives you additional 1000 exp from freeing a dog on a persuasion check that might fail. Which is to say, pretty crap as a talent.
Most of the cryptic stuff the animals say are pretty useless, might as well google the quest.
Look at it another way. Most talents increase your combat effectiveness, which is pointless since you could win combat anyway. Pet Pal adds actual story!
