<p>FREMONT -- A 41-year-old Fremont man whose dog was shot by police officers when they forcibly entered his house looking for marijuana plants has a prescription from his doctor to use pot and a certificate from the Oakland Cannabis Cooperative allowing him to grow and possess it, according to documents obtained by ANG Newspapers. Robert Filgo and his wife, Yvette Filgo, 38, were arrested Tuesday night after seven police officers served a search warrant at their Niles home and found 79 plants in the back yard and garage.</p>
