Who know the type of dog breed used by Ivan Pavlov in his experiments? I have been racking my brain for like two days. I also need the source of the info, thanks in advance for the help. :classic:
This one looks kinda "new" but the caption mentions it was one of the "lucky ones".
One of the lucky ones. Over twenty dogs died before
Pavlov managed to successfully insert the salivary collecting
contraption. This one has electrodes attached to it's head.
