What are the disadvantages of a Shiba Inu?

Could you possibly elaborate on the negative aspects of owning a Shiba Inu? I'm particularly interested in understanding the challenges associated with their temperament, maintenance requirements, and any potential health concerns. Are they prone to certain behavioral issues? Do they require a specific type of diet or grooming routine? Also, are there any known health issues that owners should be aware of? Your insights would be greatly appreciated as I'm considering adding a Shiba Inu to my family.
