What causes my pet’s gums to bleed when he/she chews on rawhide or bones?
When the gums bleed, this is gingivitis. Gingivitis is an early stage of periodontal disease, and is reversible. Regular brushing (every day to every other day) will encourage healing of the gums and the bleeding will become less with time. If the gums continue to bleed after you stop brushing, or your pet acts painful when you brush, you should schedule an examination as soon as possible.
