It could be this dog is suffering from canine cognitive dysfunction, which is like dementia in humans. Vocalizing more is a sign of it, but there are also many other signs. Without seeing the dog in person, I can't say for certain if he does have canine cognitive dysfunction. Your vet should take him into the vet. Changes in behavior can have a medical reason behind it, and in a senior dog, any behavioral changes need to be checked out by a vet. I recommend she takes the dog into the vet on Monday. Best of luck, I hope this helps!
