If you have the puppy in your position, then take him to a local vet. And they can report it and then if you don't want to keep the puppy tell the vet that you are going to take the puppy to the Human Society.
But be careful they have utenizing healthy dogs being brought in it is all over the news try the Humane Society or City Of San Antonio or call non emergency police 210-207- SAPD
Most certainly, you will find the City Of San Antonio Animal Services are there for San Antonio Humanitarian needs.
Yes you can, that's part of their job.
