I know this question was asked a long time ago, but I keep seeing people answering this question incorrectly and so feel the need to correct it when possible.  Pistachio nuts have never been shown to cause neurologic signs.  Macadamia nuts, yes, pistachios, no.  The ASPCA (animal poison control) will verify this for you, and advise you to watch only for signs of GI upset which can certainly sometimes need therapy too.  Next time, call the animal poison control instead of asking strangers on the internet.  Their phone number is 1-888-426-4435.

As for the potential for bloat, if your dog is not trying to vomit, is not lethargic, is not uncomfortable, the risk for bloat is ridiculously small.  If your dog is trying to vomit (whether successfully or not), if he/she is lethargic, if he/she is uncomfortable, then yes, by all means, get to a veterinary clinic as soon as possible.

We unwittingly fed our terrier pistachio nuts, he was very ill but came through after a couple of very worrying days, we were completely unaware of the danger.

Pistachios are not toxic to dogs.  The his fat content may lead to stomach upset and/or loose stools etc; But they aren't toxic.  Check your facts before you start to scare other people into a tailspin.

I think probably don't worry. My 16 pound min pin mix got into a bag of pistachios while I was gone for a few hours. She bit open the shells and ate the nut inside of at least 25 pistachios. I was worried at first but she didn't act any different than usual so it was fine. Her stool was harder the next day (and full of nuts of course). Then 2 days later I woke up to her throwing up around 6 am. It was just bile the first time then the second time it was bile with a big pistachio shell in it. Then she was fine. She went outside to poop and pee as normal then sprinted inside hoping to get an early breakfast but I decided to wait an hour to feed her just to make sure she was finished throwing up. Once I saw that she was feeling fine and finished throwing up I fed her breakfast and she sure went after it. No problems after that.
