Getting a new dog will make you happy again.Lost my girl, a Yorkshire Terrier at the age of 15 last December. She was no pet, she was a member of the family. Will never get over it. I am a dog person but I wouldn't get another dog ever. You will live to see them perish and I wouldn't go through that again.
If you want to feel the pain of losing someone that loved you purely and unconditionally and you loved them back the same, get a dog.
