Sniff Sniff

Have you ever gotten those really annoying runny noses? How it's sniff after sniff, tissue after tissue? Usually we get them with allergies or a slight cold well not for Boomer. Today I saw him sniffing a lot and I couldn't get the chance to take an actual look because he just couldn't stay still, so I waited for the perfect chance to take a better look. Once I was given that chance I realized how dry his nose was becoming. It felt like a scrape, hard, bumpy etc. There's some sort of outlining around his nose like dry skin building up. I was confused on how his nose was so dry yet sounded as if it were so runny. I went onto 'petmd.com' and read that if a dog has a moist nose it means good hydration. If it has a dry nose that's a sign of no hydration and with no hydration the nose usually becomes itchy and dry which causes the dog to sniff a lot due to irritation. So I realized my dog has been low on hydration. Here's a look of my dogs (Boomer) nose.
