Visitors advised not to swim in lake and keep dogs on leash

The Martin County Sheriff’s Office believes a toxic algae bloom is to blame for killing one dog and making six others sick.

Necropsy results show blue-green algae caused the deaths of three dogs playing near the St. John River more than a week ago.

The warning from New Brunswick's chief medical officer of health comes less than a week after three dogs died as a result of what is suspected to be a blue-green algae bloom.
