If your Great Pyrenees is anything like ours, they are either hard at work patrolling the property and barking at real or potential intruders or they're sleeping. All that hard work can get Pyrs into more than their share of situations! Even with coats like polar bears, your Pyr can still end up with scratches, scrapes, itchy areas and other random irritations and abrasions.
A Great Pyrenees with a small skin issue reminds me of that old Monty Python bit..."Tis but a flesh wound" and his arm was cut off. Our Pyrs would keep going and going, but we actually may know best. On a VERY few things, if you asked your Pyrs' opinion.
Our Great Pyrenees, Zoe, passed away six years ago (seems like yesterday) and I know she was convinced the minute she left things would quickly go to hell in the proverbial hand-basket. She was right. We still miss her Great Pyrenees dignity and majesty, though Skadi and Tili have filled our hearts in their own way. That is Ska∂i in the tube product image looking at the bowl of shea butter.
