LOL. I had to laugh when I read that your grandson will probably be more interested in the PS4 than Bella!
I am sorry to hear that Bella is sick
What a marvelous thing to find a vet who is not only a yorkie owner but also a breeder! I hope she can figure out what is causing Bella's cough. I hope you find out that it isn't anything serious.
Have you contacted Bella's breeder to let her know that something is wrong with her?
