Loss of a good friend

This is my dad with his beloved Riley. Look at that sweet little doggy face! Saturday afternoon Riley had a heart attack and passed away. My dad lost a wonderful friend, and companion.
When I was growing up, my dad never seemed to be much a dog person. I was allowed to keep cats and dogs as they wandered into and out of my life, but Dad never seemed to pay any attention to them. When we lived in Florida my mom and dad got a dog (I think he was a huskey/chow mix) and my mom really liked him. She named him Suds. We were all pretty close to Suds. And I'm sure Dad liked him just fine.
But he really had a bond with Riley. And Riley thought he was the protector of my dad. So, Riley slept outside my dad's bedroom door every night. He had an important job, and he did it very well. Rest in peace, Riley. Dad is safe in your care as his angel dog. Thanks.
