I've heard about it with light posts and I've heard about it happening with sewer grates & manhole covers as well.
Light posts I can understand, but sewer grates and manhole covers?! Why in the world would they be electrified?
@imbj I had a 12 year old diagnosed with a mast cell tumour. It was a deep one and nothing to be done. She had had a wonderful life running free, two very successful litters and had 2 CCs and an RCC so although she never finished we didn't complain. There was only one thing to be done in the end and she lies in the sunshine along the bottom of the tennis court with generations of her forebears and offspring.
I am not sure this article would have been any use in her case but it was a fascinating read. Many thanks for finding it.
@imbj - Thanks for posting this... any treatments for this in dogs is great and great that there is ongoing research ongoing for all cancer in dogs and humans too!
