If you notice your dog's gums are:
* Pale: This could indicate anemia or shock.
* Red: This could indicate inflammation, infection, or gingivitis.
* Yellow: This could indicate liver problems.
* Blue: This could indicate a lack of oxygen, which is a medical emergency.
It's important to check your dog's gums regularly as part of their overall health routine. If you notice any changes in colour, consult your veterinarian immediately.
