I am so sorry about your loss. I am going through the same thing. On march 22 I lost my 3 1/2 yr old Deemo tragically. My other dog has not been the same since (eating, playing or popping). I joined YT also to see what I can do about how depressed And lost Inwas feeling without him. I felt guilty looking for another dog too. But the house feels so empty, so I searched on here and found a breeder. I am sending my deposit in today. But will not get the puppy for another 8 weeks. Please let me know how you feel when you bring your new puppy home? I loved Deemo so much that I always said I wouldn't get another dog if anything happened to him, but being only with one sad dog is not helping.
