Alucard curled up into a ball of sorts, to try and help so he didn't get too beaten up as the oddly comfortable and warm yet thick wet tongue threw him around inside the mouth a bit. Luckily, Alucard seemed to be not being hit by the dog's teeth,m as it could take a lot of energy to regenerate that type of damage, moreso if he had potentially gotten decapitaeted or limbs being torn off or something.
