Snoring Dog

I have written many times about our dog, Zoe.  She is now 12 years old.  Zoe has been a great dog.  She has slowed down somewhat but still occasionally has, what we call, running spells.  She is diabetic and needs two shots of insulin each day.  She does pretty well with the shots but I am sure she isn't real fond of them.  As she gets older I think one thing she does more and more is to snore when she sleeps .  It is funny at times to stop and listen to her.
