Hi. I have used flour for years to stop bleeding when I cut my pug's nails too short. They are very thick and crooked. The vet said this was safe and non-toxic. I just put some flour in my palm and dip his nail in it. It usually stops the bleeding immediately. Flour can be used for other minor wounds on your dogs body too.
use corn starch, flour or styptic powder. After the blood stops put a drop of Krazy glue on the tip or the nail and let it dry. after its dry no more bleeding.
