Wow! But like you said there is 5 so that is understandable. Because of Samsons little toy swallowing accident this was an expensive year for me! My insurance covered more than half but I still spent $1000 of my own money on it plus everything else. I was just thinking about that when I picked Samson's allergy meds up on Saturday, I spend $270 a year on his allergy medicine alone! But I agree 100%, they are worth EVERY penny!
