Even though I never had a pet of my own, I know what it's like to lose an animal friend. My aunt's 2 dogs, a poodle mix named KW and a Bichon Frise named Sparky died within a couple years of each other, I was a kid when they both died. KW was 11 when he died and Sparky was either 14 or 15 and died from Diabetes complications. I loved those two so much!
My aunt and uncle who lives in Pennsylvania lost a Westie named Biscuit at around 13 years of age, I don't remember how she died though, but they didn't get another dog since then.
My aunt and uncle in South Carolina lost their 2 dogs and a cat. BJ was first and he was 13 when he had to be put to sleep, Buddy died on his own at around 15 and the cat, Kit Kat also died on his own because he wasn't eating for quite some time before he died.
All of these animals will be missed.
