Nostalrius Begins - Quality wow vanilla realm (1.12)

I decided to level an alt and chose hunter, now i got the pet and I tamed a boar I know how to feed them nice stuff since they are rebelious at first, I kept him fed and he was green every time I checked ( green hapiness not poison lol )

Still the fakkin boar ran away 3 times alreaddy resulting into calling my next boar pumbafour..
Could this be bugged? I use luna unit frams but I check in character screen ( c ) and there it says happy.. How come this is happening.

Cheers
