Sorry for your loss. Some may think ffs it’s a dog but when they’re with you for so long it’s hard.
Time is better than puppies, don’t rush into anything.
My other dog is an 11 year old Rott. He’s got a grey beard and is slow to get up sometimes. It’s hard to think about but I got him from a rescue and he’s been all over with me, had a great life.
It will hit me hard but you’ve just got to remember the life you’ve given them and the life they could have had.
