Old setter growing a nail in her tail

[spinny]

Hi I'm new on here
I have just discovered a toe nail growing in poppy's tail,
She is 11 1/2 years old and ageing very quick, she gets very stressed out when going tothe vets also cause of her age I really don't want to put her through a visit as we have talk things over (hubby and me) and have decided we wont put her through any surgery.
Was just wondering if anyone else had have this happen with their dog??
Would be very gratefull for any advise x
