I am very sorry to learn of your and your Wife's loss of your beloved "Scout." You can easily tell through your writing, just how much Scout was loved, adored and cherished by you and your lady and how he was considered an important member of your family. All dogs should be so blessed and fortunate. 16 years is an extraordinary life time for a pup as you know. But the truth is "Forever" would not be long enough.
I am glad you got those extra months of Feb. to May. That is wonderful news and something to be grateful for.
They say by agreeing to end our beloved pet's pain & suffering, we make a bargain to transfer their pain & suffering onto ourselves. Then we must defuse it, through the grieving process. This is what you and your wife are experiencing.
It sounds like "Scout" may have been a "Spirit Animal" for you. For some, they only come around once in a lifetime, for others they never occur. We should all consider ourselves to be very, very blessed to have had such an experience and know such unconditional love in our lives.
Kind regards & my sincerest condolences,
Thank you so much James for the well thought out reply. That was the phrase I was looking for, Scout was my spirit animal.
