Dog food expert (1)

Our expert Nicola Lakeman MSc BSc(Hons) RVN CertSAN CertVNECC VTS (Nutrition) works as the nutrition manager for My Family Vets, a nationwide network of local veterinary practices providing expert care online and in-practice.

Nicola graduated from Hartpury College with an honours degree in Equine Science and subsequently qualified as a veterinary nurse in 2002. Nicola has written for many veterinary publications and textbooks. She is the editor of Aspinall’s Complete Textbook of Veterinary Nursing, as well as one of the consultant editors for The Veterinary Nurse.

Nicola has won the BVNA / Blue Cross award for animal welfare, the SQP Veterinary Nurse of the Year and the SQP Nutritional Advisor of the Year awards. She also recently gained her Master’s degree in Advanced Veterinary Nursing from Glasgow University.

What ingredients should you look for and avoid when shopping for dog food?

According to Nicola, knowing what to look for and avoid when buying dog food depends on your dog’s individual dietary needs. To find that out, she recommends first speaking to a veterinary practice to provide your dog with a nutritional assessment. With this, you’ll be better placed to make sense of the “not overly helpful” naming of ingredients on UK dog foods.

Nicola also recommends being aware of negative perceptions of certain ingredients listed in dog food. “For example, ‘by-products’ are any part of the body that isn’t muscle. Liver would therefore be classed as a by-product, despite the fact that it is a superb source of vitamins and minerals,” she explains.

Is fresh dog food necessarily better than processed?

“Not necessarily,” says Nicola. “We all know that frozen vegetables actually have higher vitamin content than some ‘fresh’ foods, especially when they have been transported and stored in refrigeration units for long periods of time.”

In reality, “how the food is processed and stored is very important in maintaining nutrient levels. Good food companies will test all of their diets to ensure that the nutrients are at the levels stated on packaging until the expiry date.”

What are the differences between wet and dry dog food?

“The only difference is the water content,” says Nicola. “Wet foods can have between 70-80% water, whereas dry food typically has 6-10%. The water content only has to be on the ingredients list when it is over 14%, which can make comparing different diets difficult as you need to remove the water content and compare like-with-like. We compare the diets on a dry-matter-base.”

How much raw dog food should you feed a dog?

Based on current scientific research, Nicola does not recommend raw feeding due to bacterial safety issues. “Research published only last month showed that raw-fed dogs had high levels of antibiotic-resistant bacteria in their stools. This does cause a potential health issue for the public.”

If dog owners are insistent on feeding their dogs raw foods, “a DEFRA monitored raw diet should be sought”, says Nicola. “These diets are routinely tested by DEFRA for bacterial levels. Owners also need to be educated in food preparation, handling and hygiene techniques.”

What dog food brands would you recommend?

“I only recommend pet foods that I know are developed by veterinary nutritionists, who test every batch of their food for nutrient levels, have short term and long term studies of their diets, and the food is complete and balanced,” says Nicola. “Many food companies develop their foods by formulation using spreadsheets and don’t research their foods through feeding trials.”

Nicola also wants to know how the food is manufactured, what quality control measures are in place during the manufacturing, and where the ingredients are sourced from. “Can the manufacturer provide information on any requested nutrient or the calorific values for their pet food? It is impossible to know everything about all pet foods that are available, but the pet foods that I would recommend meet these requirements.”

Due to the Veterinary Code of Conduct, veterinary professionals are unable to endorse specific products, but we believe the above products would fit Nicola’s guidance and criteria above when looking for the best pet food products.
