The first time I was looking to get a dog I initially went to the humane societies near my place in the south west and was told by a lady working there that if I was serious adopting I should consider the animal foundation specifically because they are a kill shelter so I could go down there and potentially save a life.
I've been there many times since then and always found the facilities clean and the volunteers/workers friendly and knowledgeable. They really want to find homes for the animals, the dogs that are in danger of being put down have extra signs on their kennels pleading with visitors to save them. I think they try to work with what they have and do the best they can.
That said both of my dogs are from animal foundation and they are the best dogs. i wish I could take them all home! For the adoption fee you get a your animal spayed/neutered, micro-chipped, shots, and a free visit to the vet. My first dog had an ear infection which they were very upfront about and it was nothing major. When it came time to get a second dog they were very helpful about finding the right personality to go along with first girl.
I highly recommend this place if you're thinking of a new addition to your family.
