Also, adding another dog/puppy to the household right now is not a good idea.
He may decide to get rid of it.
It won’t be pretty.
Some dogs prefer to be the only dog in the household no matter what you do.
Especially if they were not socialized as puppies.
It would be best if you discuss this with your vet before doing anything impulsive.
I would take care of the dog you have now first, baby steps. See how it goes. He may never like other dogs.
PS: If you decide you would rather have a new puppy, instead. I know, it sounds awful, but it happens all the time. People give up the older dog instead of returning the puppy.
I hope you will contact a German shepherd rescue (just google to find one closest) and discuss your concerns, he is still young and has a good chance of being rehomed.
