1) Red and/or Bleeding Gums
Normal and healthy gums are pink in colour. When pressed, gums should lighten to a paler pink colour and then return to the normal pink colour when you take your finger off them.
Redness in your dog’s gums can mean several things. If your dog has not been under the sun or subject to hot weather conditions, you can rule out overheating or heat stroke as a cause of the redness. On the other hand, bright red gums are a sign of inflammation (gingivitis) or infection which can be caused by stomatitis or periodontitis. These dental diseases also make your dog’s gums more sensitive and prone to bleeding. What pet owners may notice is blood-tinged saliva, blood on chew toys or spots of blood in the dog’s bedding.
