Description

  The present invention relates to a reversible thermochromic pet garment and a reversible thermochromic pet garment set. More particularly, the present invention relates to a reversible thermochromic pet garment and a reversible thermochromic pet garment set for relieving cold outdoors.

Conventionally, walking is essential for pets such as dogs, but if you take a walk outdoors when it is cold, there is concern about poor physical condition and illness due to the cold, and pet clothing has been proposed to prevent it .
Although the pet clothing can relieve the cold by putting it on the pet, the effect cannot be grasped. Therefore, it has been disclosed to produce a pet shoe using a cloth made of a temperature-sensitive color-changing fiber and grasp a health condition such as whether it is cold or sweating when walking, (for example, Patent Document 1).
Even if the temperature of the shoe can be confirmed by the color of the temperature-sensitive color-changing fiber, it cannot be heated, so that when the environmental temperature is low in winter, the pet may become sick or sick. It cannot be prevented sufficiently.
