It depends which food you buy. Many of the foods we sell on Paws customise the size of their kibble for the life stage and breed of your dog.
For example, Canine Choice for large adult dogs has bigger kibble than Canine Choice for small puppies. The bigger kibble takes more effort to chew and helps to stop them from eating too fast (which can lead to a sick-y situation, as you probably know!).
Not sure if a particular kibble is right for your dog? Our team of pet-loving experts would be more than happy to talk you through it. Do give us a shout at firstname.lastname@example.org
