Update on poisoning of dogsAs previously reported there have been fatalities in dogs this season in the El Sargento / La Ventana area. It was suspected that the dogs had ingested a poisonous substance. Based on presenting signs and the progression of those signs a substance called tetrodotoxin which is commonly found in puffer fish was suggested. The problem was that no one had seen their dog chewing on a puffer fish. A new event has now occurred in the last 48 hours which seems to elucidate the problem more clearly. A group of 6 young dogs were taken to the beach around 7:00 AM. The person that was with them observed them chewing on dead sea slugs that had washed up on the beach recently following several days of high wind and waves. The slugs were taken away from the dogs, their mouths rinsed with sea water and all the dogs were removed from the beach. Approximately 3 hours later all the dogs but one were showing signs of toxicity (salivation, vomiting, diarrhea, intense abdominal pain). All the dogs were taken to a veterinarian in La Paz. At this time 4 of the dogs have died, one is still being treated and one showed only very mild signs and is doing well.
An internet search reveals that sea slugs can sometimes have very high levels of tetrodotoxin in their skin (the same toxin is present in puffer fish and a number of other marine animals) and there are known cases of fatality in dogs from sea slug exposure in other parts of the world.
The toxin is very potent that even small amounts can be fatal. Dogs should not be allowed to chew on any marine animals on the beach.More information can be found in the following link.
It just goes back to the same old rule that you have to watch your dog closely and monitor what is in their mouth. Easier said then done. Lots of people bring their dogs down and only a fraction of them lose them to this horrible death. None-the-less, Ms. Inmymouthfasterthanaspeedingbullet will not have off leash access on the beach!
