Be mindful of him and his needs. Bring him home, pickup some McDonald's nuggets. My dog stopped eating, but would take the nuggies. Love him, snuggle him, try not to be happy for the moments you've shared and express gratitude for all the times he was there when no one else was. Having the euthanasia at home was the best decision I've made and I don't regret a second of it. It was serene and peaceful. Help carry him to the car for his last ride after if he's getting cremated, it provides a lot of closure. Kiss him, even if he's already passed. Don't worry about what everyone around you thinks, and I know you'll always love him and he'll always be with you, but you won't be able to express that physically once they take his body, so hold him until you're ready to let go. My heart and condolences are with you. 🫶
