There are a lot of reasons for little wart like bumps on dogs. True warts are caused by a virus and will generally go away over time when the body recognizes the virus and produces antibodies to fight them off. Another cause of little bumps like this would be what are called skin tags. These are just little skin projections, usually not very hard, that appear and are not dangerouss or necessary to remove. There can also be little bumps that appear when an oil gland duct gets plugged so that the accumulation of the oily material increases and eventually results in a bump. Obviously turmors, both benign and cancerous, can also cause this appearance, but your veterinarian can get a good idea what the problem might be by sticking a needle in them, pulling out some cells, and looking at the cells under a microscope. Most likely these are not problems and really do not need to be removed, but the next time you are in the veterinary office, just ask for an opinion of what they might be.
