More: Arnold passed away from cancer in September, 2023. He would've been 11 on April 13 of this year. He loved to play fetch and was the most loyal dog I have ever owned. He was also the smartest. He had teeth that would tear through a tennis ball in a matter of seconds, he would catch frisbees in mid air, he loved my daughters and his brother Albert (Golden retreiver) and was a big snuggler.
