My husband just came in to go to bed. One of the dogs was barking and fussing at him. He apparently leaned down growling at the 10 lb dog who bit him on the nose. I've stopped the bleeding which was profuse but I'm concerned. One is just a slice that isn't too bad but the other is H shaped at front top corner of nostril over top and tip of his nose. I'm afraid it needs stitches. He's angry and has already stormed off after trying to hurt the dog. I keep trying to explain it's how a dog reacts when they feel threatened and while this one had never bit him before my other small one has. How do I know what to really be concerned about and if I need to force an er visit on him.
