We lost our sweet boy a few weeks ago

I got my best friend Harry when he was 5 days old. We had rescued a pregnant dog from the shelter, and the rescue that helped us had a litter of puppies born 5 days before she gave birth, whose mother died in childbirth. The rescue asked us if they could bring the remaining puppies to her to see if she would take them. She did, but he was the only pup that survived. He was truly a magical dog. That once in a lifetime dog. My unicorn dog. He knew me better than most people did. I loved him with every ounce of my soul. He was diagnosed with terminal, inoperable liver cancer in April, and was given 2 months, tops. We were blessed to have him until two weeks ago. We wanted to be sure we said goodbye before he suffered, and his passing was peaceful and calm, done by the vet who had cared for him since he was a baby. We planned our vacations around what he would like to do, lol. I am going to miss his eyes looking at me, and the funny noises he made to communicate with us. I'll miss how much he hated the yellow lab that walked by every day. I'll miss him terrorizing the amazon delivery man from the safety of his fenced yard. He was a crazy barky terrier. I'll miss him sleeping in my arms every night. He was the king of our household. Today we were able to reminisce about him for the first time without me crying and having to leave the room. I know how lucky we were to have him, but my heart is so heavy. I've grieved harder losing him than literally any human being in my life. We are planning to get a puppy in a few months, but God, I miss this fella more than I thought I could.
