Common signs that your dog is stressed or scared include averted eyes, yawning, lip licking, ears back tail lowered or tucked close to the body and deep growling. Take these signs seriously and speak to your veterinarian who may recommend a behaviorist.
If your cat loves to drink water from a running tap, consider getting a drinking fountain for her. Cats in the wild drink running water and a pet drinking fountain recreates this in the home.
