Hey dear @karinxxl
I know you have dogs (or a dog) but didn't know he is a second-hand dog as you called it hehehe. How nice!
These initiatives are important, I agree with you. I believe that many of those souls that have been rescued found a loving family or a person to care for them. Unfortunately, there are some countries that don't really take care of this thing so there are stray dogs living on the streets. Fortunately, I have never seen here in Spain a stray dog in the street. Maybe it is the case just in our place. They are stray cats, but as well they have a place, usually in an abandoned plot or similar where the volunteers take care of them bringing food, building small improvised shelters and taking them to the vet to be neutered. All the dogs I see are with their owners, I have never seen an abandoned one on the streets.
Also, you are right that you have to be the right match for the dog. Also, your style of living should fit the needs of the dog. If a generally inactive person adopts a dog that needs a lot of walk and activity, maybe it would not be a great match. If the dog changes the behaviour of the new owner, then it would be great :D
The case I have seen in that family I know made me think if it is a good option... maybe they didn't have an opportunity to meet well the dog before the adoption. It is an absolutely scared dog that for months barked very loudly to everyone, just not the mother in that family. Of course, there are many many more cases where the adoption went very well :))
Thank you so much for your opinion and your great comment 🙌 🐕
