I currently have a rescue dog.
However, 5 years previous to that I was turned down be several big rescues. Because my son was 5.
I have always had dogs and my children were never left alone with a dog. Even ones we got as puppies.
All the rescues admitted that they very rarely got a dog in that was suitable for a home with small kids and they recommended we go get a puppy from a reputable breeder. Most were really disappointed they could rehome with us because we worked from home for ourselves, were active had a large very secure garden, experienced dog owners. The only sticking point was the age of ds.
We did get a puppy and later also got a rescue.
I also Foster dogs from time to time for a small breed specific rescue. And I absolutely hate people who try and shame people for rescuing from abroad or buying a puppy.
Its pointless and virtue signalling. Rescues do have very high standards. And sometimes they are very unreasonable and good dog owners can't get one. So, if they really want to rescue one, why not get one from abroad.
And not everyone can or should own a rescue dog. If someone wants to get a puppy, let them get a puppy. It's not really anyone else business.
Of course they should only get them through reputable breeders. But shit breeders get better and better at hiding they are shit.
Just let people do what they think is the right thing for them.
In all cases people make mistakes. Dogs end up back at rescues, people regret puppies, people rehome their dogs. It's no more likely to happen because the person bought a puppy.
