In pet food, rabbit can be used as a fresh meat (fresh rabbit, deboned rabbit, freshly prepared rabbit) or as a pre-prepared, dry meat meal (rabbit meal, dried rabbit, dehydrated rabbit). When the ingredient is listed simply as 'rabbit' it usually refers to the fresh form.
Although, like all meats, the quality of rabbit used in pet foods can vary, it is generally regarded as an excellent meat source for dogs. It is a great source of protein, it is highly digestible and it is completely bio-appropriate - i.e. it closely resembles the natural diet of the dog.
Rabbit meat is used fairly rarely in dog foods making it a 'novel protein' for a lot of dogs. This can make rabbit-based foods particularly useful for allergy-prone dogs as it is impossible to be allergic to a food that you have never been exposed to.
The rabbits used in pet food can be farmed or caught from the wild.
