Meet the Maine 15-Year-Old Allergic to Almost Everything

Martina Baker, a 15-year-old from Maine, needs service dog Keeva to help protect her from her severe and potentially deadly allergies. Martina suffers from a rare condition called mast cell activation syndrome (MCAS), which causes her to have allergic reactions to everyday things like perfume, flowers, recently mowed grass and cleaning supplies. She uses a mask when she’s out in public to block the different smells.
