Dumped Dog

Someone dumped a nice dog on La Ropa yesterday. Pregnant, of course. Friendly, agreeable. Looks like a cross between a chocolate lab and an Xoloitzcuintle, the hairless dog. She probably weighs about 35 pounds.
We'd like to take her in for spay and help finding a home. We want to make sure they will take her before we take her to them.
How do we contact the animal group? Know where they are, but don't use the phone here.
We already have 2 dogs, one a La Ropa dog, and our neighbors have 3, two La Ropa dogs.
Thanks for any help.

I don't know about the phone, but whether SPAZ will take the dog depends on if they have room. We took a pregnant dog there about 2 years ago. We gave them some money -- as I recall, around $400 pesos. They spayed the dog (which of course meant losing the puppies) and kept her for a few days. Fortunately, we knew someone who wanted her and they came and picked her up. Otherwise, I think they might have turned her loose on the street. Simply because they did not have space to keep her. I know that things are very tight for them financially. Good luck!
