Article Synopsis
- The study tested the canine surrogacy approach (CSA) by comparing isotope ratios of modern dogs and human fingernails in urban and rural areas of Brazil.
- Findings showed a correlation between dog and human isotope values, with humans in urban areas having significantly higher nitrogen (δN) and lower carbon (δC) values compared to dogs.
- The researchers concluded that while CSA is still applicable in modern societies, increasing consumption of processed dog food could hinder its effectiveness in the future.
Background: Brazil is a low- to medium-income country and has the second largest pet food market in the world with 8% of world pet food consumption. The lowest-income social class spends around 17% of their domestic budget on pet food and other items related to pets. Consumers are frequently misled by advertising as there is no precise information about the main sources of protein, carbohydrates and fat in the labels, and the Brazilian pet food industry can legally claim that their products contain certain items like salmon or beef even if they use just a flavoring compound.
