A pet behaviorist is a professional who specializes in understanding and modifying animal behavior, particularly in pets like dogs and cats. They often have backgrounds in animal science, psychology, or veterinary medicine and use their knowledge to help pet owners address behavioral issues such as aggression, anxiety, or excessive barking. These experts typically assess a pet's behavior through observation and interaction, then develop tailored training plans. They may also educate pet owners on proper training techniques and the importance of socialization, ensuring a better relationship between pets and their families.
