Silver is not a particularly toxic element at least not for higher forms of life. It is among a few metals that can be implanted in the body. The ingestion of colloidal silver or silver compounds can cause a condition known as argyria which casues the skin to turn blue but causes no other health problems. This condition was once caused by people who overused used a mild germicide called Argyrol. The FDA banned this OTC medication some years ago. The condition popped up again a few years ago when it become popular for health concious people to take colloidal silver. There were many "snake oil" websites devoted to people buying their machine for making this substance. Some silver salts are irritating or corrosive such as silver nitrate but this is not due to the silver content. So unless "old blue" really starts to turn blue I wouldn't be overly concerned. Dogs have a very strong constitution and vomit reflex. For future reference a handy emetic for dogs is 3% hydrogen peroxide. Check for the dosage with your vet as it depends on weight.

Just like it say's on the tin, I found most of a roll of 120 BW film on the dog cage. It was partly unrolled, and both ends were chewed off. The dog looked happy. Being a photographer, or aspiring to it, I immediately retired to the darkroom and developed what was left of the roll As the edges were gone, I just rolled and unrolled the film in a tank of developer. There was no recoverable image. However, while I was manipulating the film in the darkness, it occurred to me that the silver in the film might cause the dog problems. 
Any thoughts or relevant experiences?

All the best

But in any case, do let us know how your dog develops ...


Hope you get a good negative..... and not a positive    :)
