Dogs’ tongues do not have barbs. Only felines’ tongues have barbs. Because dogs’ teeth can crush bones, barbs are not needed. However, cats’ teeth cannot crush bones, so they need barbs. Use barbs to remove meat from bones.
Tip:
Although the dog’s tongue does not have barbs, it also has many other functions, such as dissipating heat, drinking water, eating, expressing emotions, deciding to bark, etc.
