We advise owners to check your pets for grass seeds. Dogs, in particular, may present with sudden onset head shaking and pain after running through grass, the cluster of seeds shown was recently removed from one ear of a spaniel. Seeds also commonly penetrate between toes causing swelling, pain and sometimes a discharge, dogs may be lame and/or constantly lick the affected area. Seeds can however penetrate the skin anywhere. Inhalation of  grass seeds may cause a pet to develop sneezing and a discharge if lodged in the nose, or a cough if inhaled into the lungs. Grass seeds need to be removed to prevent ongoing/further tissue damage.
