Unless your dog has recently been involved in an accident or has ingested something toxic, the discoloration can be due to a possible internal hemorrhaging or bruising. Otherwise, your dog might have cutaneous hyperpigmentation.
Usually, it can be associated with the following: – Bacterial infection – Cushing’s disease – Effects of medications – Genetics – Hormonal issues
The obvious indication of your dog having hyperpigmentation is, of course, skin discoloration. When your furry best friend is experiencing this, not only will its skin color change, but the texture also becomes coarser and dense.
As soon as you see that the skin of your dog’s stomach is turning purple, contact your veterinarian. Honestly, it is rather complex to identify if it is an emergency case or not, given that hyperpigmentation can be both a cause and a symptom of a more serious medical condition.
