Swimming pools pose significant hazards to pets when left unsupervised. Drowning is a primary risk, as many pets lack the strength or skill to exit the pool safely particularly breeds with short snouts or small animals. Chlorinated water can cause gastrointestinal upset, skin rashes, or poisoning if pets drink it. Slippery pool decks increase slip-and-fall injuries, and electrical equipment around pools adds shock risks. To protect pets, install secure fencing, use pool covers, or supervise closely during outdoor time. Teach pets to avoid the area and never rely on their curiosity not leading to trouble.
