Courtney East Rochester, New York 12/19/2013 10:47:33 AM Good idea, but I don't know if I'll use it right now. My all-white dog only EVER goes out of the house to "use the tree". She's 14 and has no sign of anything cancerous. My mottled dog, who IS outside for most of the day in the summer, is middle aged and DOES have polyps. It's winter now. so I'd have to remember the sunscreen in the summer. Now you'll say it's important in the winter too, and I get that, but she'd still drip it everywhere with the melting snow.
