Can you put hand lotion on a dog's dry skin?

I would recommend a mild moisturizer that is fragrance free, preferably one intended for sensitive skin. If your dog's skin is dry and sensitive, fragrances in creams or lotions could further irritate his skin.

One of my rat terriers gets dry, itchy skin regularly in the winter. I've had luck with Bag Balm for him. It's a product originally intended to help moisturize cow udders and is sold in most pharmacies.

If the dry skin persists, your vet can prescribe shampoos or lotions that are medicated to help, also.
