Scott my heart aches for you and what you are dealing with ...
Two yrs. ago today we had to release my heartdog, my first GSD, Baron ... he was 4 mos. shy of 14. He was my everything .... friend, companion, snuggle buddy .... as much as I love them all, my bond with him is something that will never ever be repeated. The house is different .... as much as I love the 3 gsd's we have now, it's not the same. I don't feel the same connection and yes, it's an empty hollow feeling. We can do the same things together but I don't get the same joy.
Baron was our first GSD, then came his mate, Tala, a longhaired GSD, then one litter of which we kept two sons Rebel and Rex. ALL of them left me before Baron did ...... that family was awesome in so many ways.
You learn to move on, it gets to where the pain doesn't keep you from breathing or thinking about your boy. You learn to remember and hold onto the good times .... but the hole they leave never goes away.
you have to know they are always with us though in spirit, the lessons, the love, the priceless memories help.
It helps soooo much to share your boy here with people who care and understand. Pictures, stores whatever you feel comfortable with.
Hugs and prayers on your journey
