A puppy's face can say it all – happiness, fear, even guilt. But how do these expressions develop from an early age? Researchers at the University of Portsmouth are seeking to uncover this secret as they investigate canine facial expressions in young Labrador and Golden Retriever puppies. Dr. Juliane Kaminski, leading the study from the university's Dog Cognition Centre, explains: "We want to understand how dogs become more or less expressive with age – it's a fundamental aspect of their communication."
Participants needed are owners of 10, 12, 14, and 16-week-old Labrador or Golden Retriever puppies. They will be asked to film their pets in everyday situations for approximately one minute each, using footage that could help the research team better understand canine facial expressions.
The study has received ethics committee approval from the University of Portsmouth, guaranteeing responsible protocols with animal welfare at the forefront. Participants can rest assured that all video footage will be handled confidentially and with care.
Building on existing knowledge of dog cognition and communication, this research aims to address a lesser-understood area: how canine facial expressions develop over time. Previous studies have highlighted the significance of facial cues in dog-human interaction and inter-dog communication – but the developmental trajectory of these expressions remains unclear.
