Necrocrafts with variant body types

[The Great Pogrist]

I am seeking to create a necrocraft with a roughly canine form. The example given in the manual Beastiary 4 is generally assumed to be a biped with a claw/claw/bite routine. What, if any, concessions seem appropriate for a quadrupedal base form with only one attack (bite)?

Up the movement speed to 40ft., make a bite attack automatic (Str x 1.5 because it would be the primary natural attack) and give it a Construction Points option for the claws. Maybe up the bite damage to 1d8.
