I have rescued dogs, they are amazing and SUPER smart. They are respectful and grateful about being rescued. Do it, adopt one. it will change your life. Even elderly dogs are awesome, they are more chill but still super smart. Here in Costa Rica we have a lot of rescued dogs and there is also a big movement of people helping dogs. It is still a work in progress. But it is better to adopt a friend for life. You can't buy a friend.
