Well, even in his panther form, Grimmjow possessed human-level intelligence, while Yammy's pet dog does not... is the dog technically an arrancar? it could just be a normal hollow, which many hollows displayed never show any signs of intelligence. as for the number on its back, well yammy was violent maybe it was his 35th dog.
