I had to put my 14 year old Springer Spaniel down last Wednesday. You have my deepest sympathy.
I am so sorry for your very fresh loss, too! My husband’s uncle always had English Springers. He loves dogs so much he breaks up thinking about other friends’ and relatives’ dogs he knew well; again relayed how he didn’t make it in time for his uncle’s most-beloved Springer’s euthanasia (uncle knew he loved her and would want to see her but she couldn’t make it for his visit). Rich only ever had 1 dog, really, until he married into mine.
I pray you will heal with time, also. But you never forget. I still never forget my dog who died almost 20 years ago, or my kitty soon after that. And right now I’m just melancholy most of the time.
