Hi there One of my friend's senior dog is going to be 12 this year. She is due for her annual check up next month. Now she don't give vaccines except for rabies or usually get titers done and vaccinate if the titer comes back low. However now that she is going to be 12 is it even worth checking the titers because she don't plan to vaccinate her even if it comes back low. My friend will however still get her rabies because here it is required by law. She will also get her geriatric blood work her heart worm/lyme test and of course the exam and a thyroid test. So I simply posted this topic hereto know others opinions on this. What you say... is she doing right?
