A dog should not take 3 SNIPER RIFLE BULLETS and keep going like the energizer bunny.
I once had to shoot a dog with 5 sniper bullets before it died.
Yes they need to be nerfed a little.
A player can be killed with 1 sniper shot.
Dogs should be the same.
Sometimes, the Guard Dog will "run away from me", primarily on smaller maps. Like if they detect someone close enough, they'll run and attack that person, but then there's another opponent close enough nearby, so it goes running and attacking that person right after, and so on due to there being a "chain" of opponents, and either it gets killed because of the constant attacking, or I get killed because it's not there to defend me by "running away".
