A little baby oil mixed with a lot of water in a squirt bottle can be sprayed generously on a dog's coat and rubbed into the skin to help with dry skin and shedding. I can't remember the proportions, but if the water feels greasy, you've got too much baby oil. Also, I've discovered a "Furminator" that is used to brush dogs.....really gets that undercoat pulled up. Maybe with warmer weather, the itching has something to do with the coat too. The Furminator is crazy-expensive, but worth every single penny! My dog loves it and this household will never be without one again.
