Dogs with straight hair have a smooth, silky coat that lies flat against their body. This type of coat is relatively easy to care for, requiring only occasional brushing to remove loose hair and dirt. Some popular dog breeds with straight hair include the Beagle, Boxer, and Labrador Retriever.
Straight hair can be an advantage for dogs that live in warm climates, as it helps to keep them cool. It can also be beneficial for dogs that are prone to skin allergies or other skin conditions, as straight hair is less likely to trap dirt and allergens.
