Tailored size: The dog bed size designed specifically for small pets weighing around 4 kilograms is 40x12CM, ensuring that pets have sufficient comfortable space. This size will neither be too large to make pets feel insecure, nor too small to make pets feel constrained. Convenient transportation and packaging: Pet beds are vacuum packed during transportation for easy carrying and storage. However, please note that due to compression during packaging and transportation, there may be a 2-4CM error in the appearance of the product, which is a normal phenomenon. Restore elasticity and optimal use: Before the first use, gently shake and pat the bed, then patiently wait for 48 hours. In this way, the filling material inside the bed will gradually restore its elasticity and supporting shape, providing the best sleeping experience for pets.
