Oh My. Honestly, the pain never ever goes away. My heart knows RB Cody is gone (same with my wonderful parents), but my heart still aches every single day. Some days I cry uncontrollably some days I deal with it. But it is an open wound.
I believe that getting another dog or cat is a wonderful thing. You will know when you're ready. I think of it as not "replacing" the pet you lost, but giving love to an animal who needs you. To me, it's a different personality, so it's a new adventure. But I do call Logan "Cody", and have all their pictures around the house. Gone but never ever forgotten.
