Every summer the end of Bullet's ears get injured. The cuts don't seem to hurt him and they never gets infected, but once open they generally don't heal over until winter. We live with the occasional blood splatter up the wall or spots of blood on his dog bed.
The cause of the injured ears is swimming. When the weather is nice it's the perfect safe exercise for him. Every time he gets out of the water he drops his toy and shakes, causing his big ears to slap against his neck and head. He shakes like he does everything else in life - he gives it all he's got!
All-in-all the ears are minor. Once the snow hits and his ears heal it's his feet that take the beating. With the icy ground frozen solid and no water to swim in, the running, turning and slamming on the brakes wear his nails down. Nail injuries can be serious in a Giant Schnauzer and I prefer to keep Bullet's feet in as good condition as possible. Boots will be in his wardrobe again this winter right from the start of the season.
