It is important to think about what type of breed your dog is when buying dog food, the Pet Food Manufacturers' Association (PFMA) has said.
Michael Bellingham, chief executive at PFMA, said that certain breeds are more prone to health problems, so it is a good idea to buy a dog food that helps defend against this.
He said: "You can buy dog foods that can act to help support breeds at risk, including dietary components - such as a kibble with technology that allows a degree of teeth cleaning, a diet with reduced purine content to help reduce the risk of urate stones and a food with ingredients that help with mobility and joint care."
Mr Bellingham added that long-haired dogs have different nutritional needs to short-haired ones. Long-haired breeds may suit dog food rich in specific proteins, such as certain amino acids.
The PFMA represents the leading manufacturing companies within the UK pet food manufacturing sector.
