Lost my little doggy.
So, so sorry for your loss. I know it hurts like heck and there's nothing you can do about it.
I had to make the call to put my great big fluffy Goldendoodle down on Christmas Eve 2018. He gave us 14-1/2 absolutely terrific years but he wasn't going to make it another day. Still tough after 3-1/2 years as he was "my" dog - followed me everywhere. I will say time helps but you never forget.
