The salmon are running in the streams again, and while this is a very amazing (and unique) event, it can be deadly for our furry little friends...

A favorite Northwest seafood could be deadly to your dog .

SEATTLE - Daisy is eager to investigate the sounds and smells of the park. Just glancing at her, you wouldn't know Daisy's still recovering, but if you look closer, the signs of her struggle to live are visible.
"How loose she is, she lost a lot of weight,” said Amy Greger. “She did not eat at all for a week, very little water.”
There were multiple trips to the vet.
"They did ultrasound, x-ray, trying to figure out what it was, still nothing conclusive," said Amy.
Until a specialist asked one key question: Had Daisy eaten any fish?
"It was like three, three-and-a-half weeks before symptoms showed up. We had salmon for dinner,” said Wiktor Greger.
"I had a little piece of raw salmon on the plate and I thought oh, I'll just give it to her. She wolfed it down, was all happy and everything was fine."
The Gregers had never heard of salmon poisoning.
"Have quite a few friends who fish and no one knew anything,” said Wiktor.
Dr. Cherie Guidry of Helping Hands Vet Clinic says most people don't know not to feed dogs raw fish.
"If left untreated, 90 percent of the cases are fatal, the dogs will die within 2-3 weeks,” she said.
After weeks of antibiotics and de-worming treatments, it’s safe to say you won't find salmon in the Greger's kitchen, but you will find their survivor.
If your dog gets a hold of raw salmon get to the vet. And remember, sometimes the symptoms take weeks to show up and there are other dangerous fish.
There's a video if you want to watch!

And some information from WSU
Salmon Poisoning Disease
This information is not meant to be a substitute for veterinary care. Always follow the instructions provided by your veterinarian.
Fishing can be wonderful recreation, but sharing the catch with your dog can be an act of kindness that kills.
Salmon Poisoning Disease is a potentially fatal condition seen in dogs that eat certain types of raw fish. Salmon (salmonid fish) and other anadromous fish (fish that swim upstream to breed) can be infected with a parasite called Nanophyetus salmincola. Overall, the parasite is relatively harmless. The danger occurs when the parasite itself is infected with a rickettsial organism called Neorickettsia helminthoeca. It’s this microorganism that causes salmon poisoning.
“Salmon poisoning occurs most commonly west of the Cascade mountain range,” says Dr. Bill Foreyt, a veterinary parasitologist at Washington State University’s College of Veterinary Medicine. He adds, “Canids (dogs) are the only species susceptible to salmon poisoning. That’s why cats, raccoons and bears eat raw fish regularly with out consequence.”
Generally clinical signs appear within six days of a dog eating an infected fish.
Common symptoms of salmon poisoning include:
■lack of appetite
■swollen lymph nodes
If untreated, death usually occurs within fourteen days of eating the infected fish. Ninety percent of dogs showing symptoms die if they are not treated.
Thankfully, salmon poisoning is treatable if it’s caught in time. A key to its diagnosis is telling your veterinarian that your dog ate raw fish. If you have a dog that wanders, or raids trashcans and you are unsure of what it’s eaten; consider the possibility of salmon poisoning. Salmon poisoning can be diagnosed with a fecal sample or a needle sample of a swollen lymph node. Detecting the parasite’s eggs as they are shed in the feces confirms its presence. The rickettsial organism can be detected in a needle sample from a swollen lymph node. The combination of symptoms, and the presence of parasite eggs or the rickettsial organisms, are enough to justify treatment.
Given the severity of the condition, treatment is relatively simple. Your veterinarian will prescribe an antibiotic and a “wormer”. The antibiotic kills the rickettsial organisms that cause the illness, and the wormer kills the parasite. If the dog is dehydrated, intravenous fluid are given. Once treatment has been started, most dogs show dramatic improvement within two days.
Next time you are fishing or purchase raw salmon and you hear the familiar begging whine of your dog, ignore it. They may not understand it, but not sharing the fish is the best thing for them. This will save them from suffering salmon poisoning, and save you from a veterinary bill.
