Poor Dylan, it does rather sound like a grass seed,

if he has his head on one side

when George was a puppy he perforated his eardrum from a grass seed and that was in spite of rushing him to the Vets, luckily the ear did heal

the last time George had another one down his ear

the Vet managed to just sedate him and whip it out very quickly, while i held on to him
i hope the visit to the vet goes well and Dylan does not get too stressed
