Yep!!! The shelter that I volunteer at (Berkeley East Bay Humane Society) does the exact same thing. They're very picky about who their dogs are adopted out to, and I visit there every Thursday so I can always check on your friend's babies. One thing is they're also choosy about which dogs they accept. They temperament test the dogs to see if the dog is food/dog aggressive, social, trained, easy to handle, etc. This testing is pretty extensive, but provides the shelter workers a good idea of the dog's temperament and what kind of home would be best. You can make an appointment to temperament test the dog and drop him/her off. Lemme know what they decide!
