My female dog has these blue/purple spots on her stomach and it seems to very slowly spread. What is this? Does she need to see a vet?

Blue and purple spots could be bruises and if they are spreading I would be worried that your dog may have a coagulation problem. This would be very serious and would need to be investigated. A small blood test will find out whether your dog is either suffering from a congenital blood coagulation disorder or possibly ate some rodenticide which can cause the blood not to coagulate. Of course it could also just be hyperpigmentation. There are various causes for that, one being an endocrine disorder where the adrenal glands produce too much cortisone (cushings disease). I would recommend you make an appointment for an exam with your veterinarian.
