Abscess could be caused by almost anything – an insect sting, bite wound, splinter, etc.— anything that penetrates the skin’s surface and cause an infection. As the surface of the skin heals, the animal’s immune system work overtime by sealing the bacteria under the skin surface and form a pocket of infection. These little pockets of infection are very painful and very tender. The soft swelling can also feel hot to the touch. There may also be draining of green to yellow or bloody pus from the site.
Dogs can get an abscessed tooth from chewing an inappropriate item that can splinter and pierce the tongue, gums or cheek. Breaking of a tooth due to chewing can also be a potential cause of an abscessed tooth. Dogs with an abscessed tooth may drool and refuse to eat because of the pain.
If your dog has an abscess, you should have it checked out by your veterinarian as soon as possible. There is a need to drain the pus and flush the abscess out of the pocket. Your vet may prescribe a round of antibiotics to get rid of the infection. For more information visit here.
