What are the most common signs of animal abuse, such as physical injuries, behavioral changes, or environmental indicators?
user
Common signs of animal abuse include physical injuries (such as marks, scars, and welts), behavioral changes (such as fear or aggression towards humans), and environmental indicators (such as insufficient food, water, or shelter). Other signs can include veterinary care needs that are not being met; neglected animals may require medical treatment for various ailments such as flea infestations, worms, and even tumors. In some cases abused animals may retreat or hide when people approach them. 
Signs of potential animal neglect include lack of social interaction with other animals, lack of exercise leading to physical weakness, untreated health issues due to a disregard for proper veterinary care and hygiene practices causing illness or disease.
Anyone who suspects animal abuse is encouraged to report the suspicions to the proper authorities immediately. Do not try to intervene yourself, as this could be dangerous. Depending on the jurisdiction it is often illegal to interfere with an investigation into animal abuse so leave it to law enforcement or humane society professionals.
