Dog Skin Bumps: What Causes Them

At the time of grooming your dog you may have felt bumps on the skin and there are various reasons why these appear. If you see a bump under the skin of your dog then you need not panic as most of the time these are just non cancerous lumps such as warts, cysts and hair follicles which are infected. These are skin problems which cause discomfort to dogs but are certainly not detrimental to a dog’s health.
