Why is my senior dog growling at other dogs after a coyote attack?
I am afraid you cannot fix this. At the age of 13 she is not really willing and able to play wild like a young dog may want to play. She will likely also suffer from arthritis, so playing and running more than at home may hurt. If she is not taking an NSAID or pain medicine for arthritis, and if she is showing signs of stiffness in the morning, less activity, then you should take her to your vet for an exam and prescription for arthritis pain. Once she is not painful anymore, she may want to play wild again.
There is also a possibility that she has suffered a trauma during the fight with the coyote and that this is generally making her more careful and less trusting with other dogs. She may get over it with time.
