Query: Be prepared for this thing to STINK.

My dog has to wear then as we are walking to his pee spot and as we are walking back because he is an excited pee'er. But even though I wash it thoroughly every time afterwards, it has gained this permanent stench that stinks up whatever room it's in. Not to mention that the fabric is a pain to wash in the first place.Perhaps it is well suited for someone who only needs it for special occasions.
