Figuring that I could easily create this same product, I hadn't purchased one, but tucked the idea in the back of my brain for future use. So here goes.
Have you tried any other ways of keeping your dog cool on long, hot walks? One of my neighbors hoses his chocolate lab, Roxie, down before a walk. This works great for her.
If you have pictures of YOUR dog wearing a cooling bandanna or other creation for this purpose, I'd love to share your best friend's photo on my blog. Send it to me at LetsAdoptaDogPark@gmail.com . Stay cool!
