What can gum colour tell us?
In human first aid, you can look to check if the skin is pale or their capillary refill is slow. With dogs covered in hair, it is very, very difficult. So we look at their mucous membranes or gum colour. A normal colour is a nice bright, pinky red colour. This shows good circulation. If it goes very, very pale, this could indicate that she has a circulatory problem or shock. If it is going a dark browner colour, it could indicate there is some kind of poisoning or toxicity within the blood. If there is carbon monoxide poisoning they can be really, really bright red. A yellowy cover may suggest a problem with the liver and a purple spotting may indicate insufficient oxygen within the body.
It is really important to know what is normal for your dog as dog’s can have different markings on their gums and tongue which is normal for them.
