We upgraded the heating system in our house, switching to forced air. It's cheaper and the house heats up faster. But you know what? There's a price to pay for it. I get really itchy from all that warm, dry air. At least I can do something about it with lotion and clothes. Beverly, our German Shepherd doesn't have that option. She's been itching for weeks. Finally all that itching created an infected spot on her back, which needed antibiotics. The vet shaved a little divot out of her back. She's getting better with the meds, but it's going to be a perpetual problem. What we do to improve our lives as people, sometimes has an adverse effect on our pets.
