As a dog person, I can relate to Heather Armstrong’s comment:
I just spent $20 to have my dog’s anal sacs squeezed because he�s been greasing the couch lately. That may seem a bit exorbitant for a little gland squeezing, but it will definitely go down as the best $20 I ever spent: I DON’T HAVE TO SQUEEZE THEM MYSELF.
Unfortunately, cheap trumps disgusting for me.
