Deep condolences for your loss, Cage.
Losing a dog is not like losing anything else because the way your dog loves you goes well beyond the connections we have human to human, even family.
Your dog loves you without condition. They also look to you to provide for and protect them, and at the very same time, they will lay down their life for you without thought or hesitation. A 20 lbs Jack Russell will get between you and a rattlesnake or grizzly bear. There are no words for what it feels like when your pooch curls up with you, or rests his head on your lap. I will however offer these words of ecouragement to you and your wife Cage...as someone who not only lost K9's who were family pets, but also working military and police K9's that were my in the field partners, where our lives and actions were interdependent day in and day out for years. It sounds cliche, but time does heal. What is now grief and sorrowful emotion will in time become a point of pride filled with warm feelings and beautiful memories. There were dogs I had that I couldn't even look at pictures or talk about for years after they were gone without choking up and crying, that now...I just beam and smile and cry for joy over what we shared and gave one another, and I can tell story after story and show off their pictures with nothing but delight. You will get there. And when you do, perhaps then it is time for (not a replacement....such a thing can never be)....but a new adventure, journey, and love story. Prayers for you and your wife. May your grief and sorrow pass quickly. God Bless.
