Do all dogs go to Heaven?

On Saturday we were coming home from our fabulous 4th of July celebration in Kanab and as we were driving past the Chapel in Santa Clara there was a funeral going on inside , I thought to myself wow how sad, I am glad that I don't have a funeral to go to today. We drove the rest of the way home and didn't think too much more more about the funeral and we got ready for the day. I had to take Tom back into town for work and when I got home I went to feed the dogs, Bella and Ebony. I could see the dogs just laying there Ebony in the shade and Bella was in the sun like always, sunbathing is what we called it, as I got closer I hollered to the dogs but only Ebony jumped up. I thought that was strange because she is the deaf one and usually Bella hears us coming from a mile away. I just kept hollering to them but she never jumped up. As soon as I got the kennel I could see that she was never going to jump up, she wasn't breathing. I fell apart. I started crying and hollering her name. I guess I was really loud because my two neighbors, Ben and Shellie came running over to help me. I couldn't pull myself together, Bella our little dog was dead and it broke my heart! Bella was Tom's dog since before we got married. She was the one that he came home to, he raised her from a puppy and she was his best friend and his family. We all loved Bella. How was I going to tell Tom?! I couldn't! I wasn't sure what to do...maybe wait till he got home from work and try to pretend that nothing was wrong or should I call him right now, I had no idea what to do. I called Barbara first of all to see if she could help me know what was the right thing to do but I was such a mess we thought it would be best to have her tell Tom. Tom called me a few minutes later and said he was on his way home. He was heart broken I could tell but was also really mad. I had never heard him like this he never shows that much emotion. When he got home my eyes were all red and swollen and so were his. His heart was broken and there was nothing I could do about it. He went outside to get her and as soon as he saw her laying there he started to cry and was trying to get her to wake up. It was so hard to watch him have to go through this. He wrapped her in one of his blankets and then went to find a good place to bury her. We decided to put her in the front yard under a big tree so she would always have shade. She was always trying to get in the front yard and was always coming up with new ways to get there so we thought it would be fitting to bury her there. Tom dug the hole and I went to buy balloons to let go in honor of her. We told Matty that we let off balloons so she would have them to play with up in Heaven. We said things that we loved about her and covered her up. It was just as hard as burying someone in our family, she was part of our family. We loved her so much and we always will. Our hearts hurt when we think of her being gone but we will always have the memories of her, good and bad. We will miss her barking at night even though it bugged us and the neighbors when she did but at this point I don't know if there is anything that either one of us wouldn't do to just hear her bark again. We love you Bella and we already miss you so much!
