I'm sorry your dog isn't doing well, it can be terrible to loose a fur baby. However, you could still have lots of good days before you have to say goodbye and it could be something fixable
We had a JRT named Bullet. Pretty sure he was certifiably crazy but he was our boy. He had terrible arthritis and had been on medication for a while, pain pills too. His mind was spry but his body couldn't keep moving so we put him to sleep in January. We cried a lot, but we knew it was coming.
My silky terrier was sad for quite a while, they'd been together 10 years, but we spent all of our time together, I work @ home, and she seemed to come through it ok. She came upon Bullys collar and muzzle in a box in my closet the other day and her little tail was wagging. I think she still misses him.
Hubs was ready for a new puppy after a few months, I was content with having one adult dog. We got the puppy. I do have to say I think about Bully an awful lot still, I can close my eyes and see his sweet smile, feel the silky hair behind his ear as I give him a scratch
The puppy is a good distraction though. He makes us laugh, keeps the old girl, 11 years now, moving and us as well.
I've been through the loss of pets too many times to count, but it never gets any easier.
My husband told me once that dogs are a blessing because they love us without boundaries and make us happy. They're also a curse because they don't live as long as we do and we suffer the loss. I think he's right, but they're a curse I can't live without
