Which of the following habits is essential for an animal’s hygiene?

Regular grooming is essential for an animal's hygiene as it helps to remove dirt, debris, and loose fur from the animal's coat. This practice also aids in preventing matting and reduces the potential for skin infections caused by trapped moisture or microorganisms. Grooming can enhance circulation and promote healthy skin by distributing natural oils throughout the fur, which contributes to a shinier and healthier appearance. Additionally, regular grooming allows for the early detection of irregularities such as lumps, skin lesions, or parasites, which can be crucial for maintaining an animal's overall health.

In contrast, habits like frequent running and constant feeding do not directly relate to maintaining hygiene. Avoiding bathing can also be detrimental, as some animals may require baths to maintain cleanliness, especially in specific breeds prone to skin issues. Thus, while all these practices contribute to an animal's overall wellness, regular grooming stands out as the critical activity for promoting proper hygiene.
