A Burnaby landlord has circulated to letters to residents of a rental building, asking that all tenants submit a sample of their dog’s feces, for laboratory testing.

CTV Vancouver Island reports the landlord delivered letters to dog owners in the building after someone’s pooch pooped in the stairwell, twice, and no one cleaned it up.

The landlord says tenants who refuse to provide a sample from their pet are admitting guilt, and could be evicted immediately.
