On weekends the SPCA in Galveston Texas takes dogs that need homes to both Major Pet Stores here to be adopted.
PetSmart doesn't sell any dogs. The do have a cat adoption center, fish, reptiles and birds. I think they host adoption events with the local animal shelters, but they do not carry dogs in their inventory.
I suggest you call the store...

They also usually have a notice board which might have some sellers.
