Iv put down a few pets.you never forget any of them.time just goes on ,but I remember all of them from time to time..I have 2 dogs now hank my 10 year old pit mastiff,and Brody my pit pug mix only2 years.I love them dogs even when they don't stop fighting all day ,and get on my nerve s.a dog will love you no matter what.I'll never have a friend like my dogs.I find I take there love for granted.its topical human behavior to not know what a good thing is till its gone,right.so love your dogs or any pet while there here, because time fly's by.I'm sorry for your rough decision. But that's what best friends are for.for the hard times as well as the good.god bless
