This is why treatment is aimed at eliminating the voids that form under the gums, trapping debris and infectious material. Treatment may involve reduction of overgrown gums, surgical exposure of roots, meticulous cleaning of all root surfaces so that healing can take place, and, in more advanced cases, the placement of graft materials to help replace missing bone.

There are various forms of punishment based techniques, but it is the general consensus that they are not as effective as behaviour modification methods and positive reinforcement. The American Veterinary Society of Animal Behavior states in their position statement that they “recommends that training should focus on reinforcing desired behaviors, removing the reinforcer for inappropriate behaviors, and addressing the emotional state and environmental conditions driving the undesirable behavior. This approach promotes a better understanding of the pet’s behavior and better awareness of how humans may have inadvertently contributed to the development of the undesirable behavior.”

It’s a myth that cats and dogs can see in the pitch dark. Like all animals, some light is required for the eye to function properly. Their eyes have a high density of rods, which are the cells that are sensitive to dim light. This means they can see normally with as little as 15% of light required by humans. Their pupils function much as the aperture for a camera does, dilating significantly when they need to take in extra light. Cats, in particular, have exceptionally large pupils and outstanding night-time vision.
