More: Sadie is a senior dog, but she’s still convinced that she’s a puppy and I don’t have the heart to tell her any different. This past year, Sadie has had to face a lot of different health issues, but she continues to fight. She is an extremely curious dog with a big goofy personality that brings happiness to everyone she’s around. She’s also a therapy dog, since I brought her home when I was a teenager, she’s been my best friend and family. The past 15 years she’s gotten me through a lot of dark days. In many ways, this little dog saved my life several times. Sadie is one of a kind.
