Pet Sunscreen I'm Taking My Dog To The Beach, I Want To Buy Him Sun Block/screen..what Kind Is Best?

I'm taking my dog to the beach, I want to buy him sun block/screen..what kind is best? - pet sunscreen

I do not know much about the animal, sun block, then what type or brand would be best for my dog? It is a yorkiepoo with short hair. We have no plans to stay on the beach for a long time, but I want to make sure do not get sunburn. Thank you! =)
