You mean negligent, and I agree. But since it’s a little bit of a hot button for me, I’ll give my answer:
The better rescues evaluate the animal’s personality and behavior and try to match it up with an appropriate new family. Using the example here, a dog that hates children can still be placed with an adult or family that has no kids or plans to have kids. The issue is that this very responsible practice also requires adoption applicants to be willing to be VERY honest with themselves and the adoption group. They don’t have kids now, but do they plan to have them in the future (of the dog’s lifetime)? Are they SURE? Because sometimes accidents to happen, are they willing to do what it takes to ensure the safety of their future new child or any kids that come around the dog? REALLY?
Lots of people are deeply offended by groups that screen adoption applicants. Those are the people who buy dogs from the nearest municipal shelters that doesn’t screen.
