Dogs' tongue stains are mostly caused by genetic reasons, which is normal. If genetic factors are ruled out, it may be that the food the dog eats contains heavy pigments, which causes pigmentation on the dog's tongue, resulting in a stained tongue. In addition, if the dog has symptoms such as loss of appetite and lethargy in addition to a stained tongue, it should be considered that the dog may be sick and needs to go to the pet hospital for examination and treatment in time.

If a dog is born with a tongue, it may be caused by genetic reasons. For example, if one or both parents of a dog have a discolored tongue, then the dog will have a discolored tongue. This situation is normal and the owner does not need to worry too much.

2. The food you eat has a heavy pigment content

If your dog eats food with a heavy pigment content, such as braised food, long-term eating will cause pigmentation in your dog. The tongue will turn into a flowery tongue.

Otherwise, it will easily lead to abnormal hair loss and even obesity. .

If the dog not only has a stained tongue but also other abnormalities, such as loss of appetite, listlessness, etc., it means that the dog may be sick. At this time, you need to take your dog to the pet hospital for examination as soon as possible, and then provide symptomatic treatment based on the examination results to avoid missing the best treatment time.
