Is this the SPCA that your friend returned the puppy to? http://www.spcanova.org/

If so, I am sure the pup is in safe hands. You could try emailing them to verify though. I read on their site that they don't have a facility and are just a cluster of foster homes. That almost always means they will not put animals to sleep due to lack of space (they just wouldn't take them in if there was no room). I would send them an email to make sure though.
