What kind of food is best to give an adult dog?

Right around when most dogs hit that one-year mark, or for some of the larger breed dogs that may be as late as 18 months, we like to transition them over to any adult formulated diet. You’ll surely see some foods out there that are made for quote unquote, all life stages. But I would encourage you to look for a dog food that's more geared towards the adult life stage instead of all life stages. Selecting a good quality adult dog food from a brand you trust is the best thing that you can do.

The best food for an adult dog is an adult formula food. This is custom made to suit their needs at this stage of life. The age at which a dog becomes an adult varies depending on size - small breeds generally reach adulthood at nine to ten months, middle-sized dogs at around a year, and large breeds between a year and a half to two years.
