I was going to ask if you used a crate...we traveled to a friend's in Minneapolis once and used her crate which was purely metal, no soft covering. While we were gone, he scraped up his nose to the point of bleeding...but it's all healed up now...
Bleedy Nose dog
No more bleedy nose...although his nose went from black to pink.
BTW, Ricky & Ziggy could be brothers!
