That is Dublin these days. Not to be gross or anything. He is just a dog after all...
THAT JUST GOT HIS CAST OFF!
Did you ever have a cast on your arm or leg? I did a couple of times and I vividly remember poking all sorts of sticks and pencils up the edge of the cast (in total disregard to Dr. order's otherwise) because I could not stand the itching. So poor Dublin all these weeks has probably been about to DIE of itchy leg and now he is free to scratch and sniff that poor scrawny leg to his hearts content. He is so happy.
And so are we. We just gave him a bath and he smells so much better!
