“Most commercially produced dog food is made with animal feed grade ingredients and comes dry in bags (also known in the US as kibble) or wet in cans. Dry food contains 6–10% moisture by volume, as compared to 60–90% in canned food. Semi-moist products typically run 25–35%. Isotopic analysis of dog food in the Brazilian market have found that they are basically made of maize and poultry by-products.” (https://en.wikipedia.org/wiki/Dog_food)
“Kibble may refer to: Dry compound feed, especially when used as dog food or cat food” (https://en.wikipedia.org/wiki/Kibble)
“kibble: ground meal shaped into pellets, especially for pet food”: Stuff you wouldn't want to eat but the dog might like: dried liver, plain old (good quality) dog kibble, dry cat food, other pre-made dog treats. (Oxford Dictionaries Premium)
U.S. native speaker here. Yes, we use "kibble." It means dry pellets of ground pet food. I just checked with my wife, who's a retired veterinary technician, and she confirms what I thought: the word can be used BOTH an uncountable noun--"We feed our dog kibble," AND as a countable noun for the individual pellets, "To give your dog this medicine, try hiding the pill among the kibbles."
