My best friend of almost 30 years volunteered at NEAS and she passed away suddenly last year on 6/29. In honor of her, my family adopted Riggs. 
We already had a German/Husky mix at home so she would have a big brother, Jax. Riggs loves him sooooo much, she emulates his every move. Riggs has an extra special place in our hearts due to the reason we adopted her, but she has definitely helped fill part of the void of losing my human best friend.
