I actually thought the steak would be the distraction you need to attack from the astral with a surprise attack. If the hound doesn't go down with one strike, Bobby can go for a subdual attack (effectively choke the dog out)
Stats for hellhounds are:
B A R S W L I C E ESS M
6 4 5 6 4 2 4 3 3 6 5
Initiative 10 + 3D6
Movement x2/x6/+4
Condition Monitor 11/10
Limits Physical 8, Mental 4, Social 6
Armor 2
Skills Exotic Ranged Weapon 4, Intimidation 3,
Perception 3, Running 4, Sneaking 5, Tracking 5,
Unarmed Combat 3
Powers Armor 2, Dual Natured, Elemental Attack (Fire),
Enhanced Senses (Hearing, Low-Light Vision,
Smell), Fear, Immunity to Fire, Natural Weapon
(Bite: DV (STR+1)P, AP –1)
They aren't that impressive in a one on one fight - especially if you are in close combat with them.
