Mysterious poison sickening and killing dogs at Mavericks [Updated]

[Update: The Half Moon Bay Review posted on their discussion board that they contacted the vet and there has only been a single poisoning case. The Facebook post which announced the problem has been deleted.]

From Bill Bechtell of

I just received this message from Jackie West’s Facebook page. Jackie is a vet tech at Linda Mar Veterinary Clinic. I will try to find out more details, but in the meantime you might want to avoid taking your dog to Mavericks.

Just a heads up to all HMB people — we have had multiple clients that have come in to my veterinary clinic that have dogs that got into some kind of poison whose common connection is Mavericks. There is something out there that is poisonous to dogs. These dog present with foaming at the mouth, bleeding gums and some are dying from this. One of our doctors is currently trying to contact the Harbor Patrol. Please pass the word and keep an eye out.

    Please, will everyone call and lodge a complaint with the San Mateo County Environmental Health Dept. for allowing Pillar Point Harbor to continuously remain on the Posted List of Beaches with high levels of bacteria WEEKLY.

    I mean, every week they sample the water at several locations, and THESE SAME THREE ALWAYS get flagged and re-flagged on the list. But nothing is ever done. I suppose their job is finished once the warning sign is posted…. (NOT!)

    Web Link

    “The following locations have elevated levels of indicator bacteria and are posted with warning signs:

    This list was last updated July 23, 2014 based on samples collected Monday morning.

    Ocean Beaches:

    The following beaches have elevated levels of indicator bacteria and are posted:

    Pillar Point #5 (Capistrano Beach)

    Pillar Point #7 (Surf at the end of West Point Avenue)

    Pillar Point #9 (Outer Harbor)”


    You could also put in a complaint to the San Mateo Harbor District General Manager-Peter Grenell {650-583-4962 &} but at the Civil Corps of Engineers meeting that I attended last year, Web Link I asked why the Harbor keeps coming up as testing for bacteria, week after week, and NOTHING is ever done. Manager Grennell just offered a mouth full of excuses, like: “The water in the Harbor is being polluted by livestock upstream”. {HELLOOOO…THEN DO SOMETHING ABOUT IT!}

    Please as a concerned citizen contact the San Mateo County Harbor District 400 Oyster Point Blvd. Suite 300 So. San Francisco, Ca 94080

    Voice: 650-583-4400 Fax: 650-583-4611 & E-mail:

    Took my dog on a walk from HMB to Princeton last Wednesday. 2 1/2 hours after returning home she began throwing up and was foaming at the mouth. Very lethargic . Within a few hours she was fine. I figured whatever made her sick was working its way out so I waited a couple of hours. She was fine. We are lucky. I feel she must have breathed in or eaten a small amount of whatever caused this sickness .
