Circular spots of dead turf surrounded by dark green rings are
characteristic of dog injury. Urination is a problem primarily
with female dogs. It is most problematic on bunch
grasses rather than on creeping
type grasses that can spread and recover.
Prevention and management
Train dogs to urinate away from the lawn. If possible, water affected
area soon after dog urinates to flush out salts.
