I'm sorry for your loss. I'd like to say it gets easier, but I just don't know. It's been just over a month since I had to let my best friend ever pass on. And after a month, it still feels like I've lost a part of me. We've already gotten another Rottweiler puppy, and even though he brings a lot of joy, and we are already good friends, the pain hasn't even weakened. And in some ways I don't want it to. I almost feel to let the pain weaken is to dishonor his memory.
Losing your dog is bad. It's real bad. I'm changed, and it isn't an improvement. I hope you will be able to let your pain go.
