Dogs love their owners unconditionally, even after being abandoned.

The Seminole Humane Society wrote on Facebook that the owners of Cathleen, a six-year-old Great Pyrenees mix, moved into a house in Seminole, Oklahoma, without a fenced yard several months ago, so her owners gave her to someone 20 miles away in Prague.
Seminole Animal Shelter Treasurer Marta Mattingly said they want to be "very careful" finding Cathleen a new home. However, Cathleen was having none of this.
