That's easy for me.
My very 1st own dog.
Their was a free add for 6 wk old lab/GSD mix puppies in the daily paper.
My mom and I went to see the puppies. The one puppy that came up to me to play is the one I chose.
From the 1st day she became my soul mate.
We went everywhere together. I do not think I will ever own a dog that meant so much and so special to me as her.
