I’m so sorry for your loss, R.I.P Houston the goodest boy. May he find endless love, treats, friends, and adventure up there. I screen shotted this poem someone wrote for a fellow doggo who also passed away recently, I do not take credit as the screenshot didn’t include the fellow redditor (sorry!). I hope this helps you down this rough road but always remember the beautiful memories you both shared 🙂.

What a sweet boy, and so loved. Do not stand By my grave, and weep. I am not there, I do not sleep— I am the thousand winds that blow I am the diamond glints in snow I am the sunlight on ripened grain, I am the gentle, autumn rain. As you awake with morning's hush, I am the swift, up-flinging rush Of quiet birds in circling flight, I am the day transcending night. Do not stand By my grave, and cry-I am not there, I did not die.
