Wow, that is very true.
I adopted my, at the time, 9 year old dachshund from a rescue society. I didn't know his story but I found it odd that he would keep going to a certain house while on a walk. One day I was walking him and there were people outside of that house. They asked if his name was Bailey and if I got him at the pound. I said, yes, his name is Bailey, but I got him from a rescue society. Well apparently it was their dog previously and they "had to take him to the pound because they were expecting their second baby” I just smiled at them and said "Well I bet he is much happier now." I walk by a month later and they have a collie puppy, a puppy, in their back yard. I don't get people, but Bailey is the best dog ever, and is now 14.
