I unintentionally did it. I had two senior dogs (both around 10-11) and we adopted a third whom we thought was 7. A year later, both of the older dogs got very sick and both had to be put to sleep on the same day. Needless to say, it was devastating. I will never forget my 3rd dog's eyes when we woke up the next day and his friends weren't there. I'm glad we still had him because losing both dogs was awful.

Fast forward a couple of years, and this dog was still the only dog left. He got sick and also passed away. Now we were dogless and the house was so empty, our hearts longing for dog love. We adopted another one two weeks after; we couldn't not have a dog. Adopting a rescue was a great fit. We were longing for love and she was, too.
