When the first of the 5Fs for the welfare of dogs goes wrong. Who is responsible?-a review

The importance of nutrition for the welfare of dogs is highlighted in this review. Malnutrition can be the cause of many health disorders, including behavioural disorders. On the other hand, dietary interventions and modifications, and nutritional enrichment can be used for the treatment of certain health problems and improving welfare in dogs. The paper focuses on data collected from the literature on omissions in the diet of dogs for which owners, food producers, veterinarians and/or animal welfare societies are responsible. Manufacturers are responsible for the composition, quality and safety of commercially available dog food. They are also responsible for the clarity of the feeding guidelines that are provided on the labels. Owners are expected to know what type of food is most suitable for their dogs in terms of any particular allergies or intolerances they may have, as well the quality and quantity of food they should feed their dogs. It is especially important for owners to be aware of the risks of using raw food in dog nutrition. Due to the special social status that dogs have in their owners’ families, owners are increasingly interested in the quality and safe nutrition of their companions. This should be a challenge for veterinarians to master the necessary knowledge of pet nutrition, and to develop and provide advice and consulting services in this area within their practice. Owners’ interest in good quality and safe dog nutrition should also be a challenge for animal welfare societies to include information on nutrition in general dog ownership education
