Older dog barking constantly

[Jaelyn2002]

I have an 8 year old morkie (Maltese x Yorkie) and he would never bark. He was the quietest dog. But lately he has started barking constantly. Anytime anyone comes over he barked. He will bark when he wants food or sometimes just sit and bark at you for no reason. A month or so ago he fell off a table and hurt his shoulder. We took him to the vet and got him meds and he has been cleared. He also got a complet checkup and nothing was wrong. All his tests were negative for anything. I just can’t figure why he has started barking. We haven’t tried a barking collar and don’t really want to try one. How can we get him to stop barking so much??
