I totally understand your confusion. I have experienced quite a bit of loss, both human and animal, and I will tell you that it varied from situation to situation for me. I lost my first personal bunny unexpectedly. I waited 4 years to get more rabbits. Then, I lost my little girl, Korra, to complications during her spay. I thought I was done, and I would just care for Ashe until she passed of old age, but then I saw Korra’s brother a few months later (from a later litter) and I just had to have him. I am very glad I did not wait this time.
But then there is the situation that came up a few months ago. I lost my cat I grew up with since I was 5… He was 17 and it was expected, because of some health problems he was having. So, the grieving process was a bit strange. I would say I’m done grieving, but anytime I go out to my parents farm, I still expect him to come running to the gate to meet me. I have decided I’m not really a cat person, and it turned out I was just THAT cat’s person
He was my best friend but I was happy to see he was no longer in pain.
So, back to the first rabbit I lost ( I think this would be the most relevant). I had moved to a new house. My best friends mom was the landlord and knew I was bringing my rabbit. She had given me permission to keep her in my room. Well, on the second day, she changed her mind. We all decided on days that the parents would be in town working on the house we would put her just outside the house in a shaded area. It wasn’t very hot at this time and we planned on convincing them to let her back in the house when it heated up. Anyway, the sun switched sides of the house and she died from heat stroke…. so I felt immense guilt for a long time. Even if I was allowed to get another rabbit I probably wouldn’t have for a long time. I still feel pretty horrible about her death, because it was very much my fault.
I don’t think your situation is your fault at all… you have no control over a dog, and it sounds like you weren’t even around. It would be awesome if we could all see the consequence of every single action we made all the time, but it doesn’t work that way. I am sorry for your loss, and I think it is up to you to feel out when you are ready to accept another bunny into your life. And you are correct when you say you are not replacing the ones you lost. Good luck and *hugs*!
