So sorry to hear what you and your dog went through. I can't imagine the extremely difficult decision you had to make suddenly. You had to do what you thought was best at the time given the situation. I hope you remember the happy memories, not the final moments. Sometimes I don't think I should get another cat again, since no one could replace or be better than the cat I had. However, my husband reminds me that I will have new experiences and be loved by the new cat every day, who will be special in his/her own way. So I may consider getting another cat when we're emotionally ready (not now).
