Yes, I can tell you from my person experience that the California Newt, which is fairly similar to a salamander, is poisonous to dogs, here is my story:
We were hiking up a trail in the San Gabriel Mountains after a rain. My 20 pound terrier, spotted a newt and gave it a very close sniff, there may have been contact between my pooch's nose and the newt. About 5 minutes later he collapsed on the trail; he was shaking and his legs became stiff. We put him in a backpack and began the long hike out. He looked bad, glassey eyed and confused. We figured that he must have been poisoned by the newt. My fiance (brilliant woman) noticed that he was licking his face a lot so she used all our drinking water to wash off his nose. I think that saved the day by rinsing off the newt's neurotoxin. After about 30 minutes he began to act more normal and was soon kicking to get out of the bag. We put him down on the trail, he shook himself off, and was right back to his old self!
