What is the difference between human CBD and pet CBD?

Could you please elaborate on the distinction between CBD products designed specifically for human consumption and those intended for use by pets? I understand that CBD, or cannabidiol, is a non-psychoactive compound derived from the cannabis plant, but how do these products differ in terms of their formulations, intended effects, and any potential safety concerns when administered to humans versus animals? Additionally, is there a need for different dosages or administration methods depending on the intended recipient?
