A dog’s heart rate rose 46% when an owner said the words “I love you.” The company said the result was recorded in four animals monitored continuously for a week.

The company said the four dogs wore heart-rate monitoring collars for 168 hours (one week) while staff recorded events and interactions. Canine Cottages framed its report around three interaction types — the spoken phrase “I love you,” physical cuddling, and owner return — and said the animals showed different heart-rate patterns for each.

According to the company, the 46% figure was associated specifically with owners saying “I love you,” while the same dogs registered lower heart rates during cuddling. Canine Cottages summarized the finding in a statement: “a dog’s heart rate rises 46% when hearing ‘I love you.’ Experts say it proves that they physically respond to your affection.” The company and outlets such as CompanionLife publicized the results and the public reaction that followed.

The report prompted widespread attention on social media and in online comments, where dog owners shared anecdotes about how words and touch affect their pets. Canine Cottages said the emotional response underlined the idea that “our words of affection can reach across species.” The company did not publish full methodological details, and the published account focuses on the headline numbers and the general patterns observed across the three interaction types.

Independent researchers and science communicators often note that effects measured in very small samples should be interpreted cautiously. This study involved only four dogs, each monitored over a seven-day period, and Canine Cottages presented its data as part of a company report rather than a peer-reviewed journal article.

Readers seeking broader scientific context can consult longer-term studies of human–animal interaction. Positive interactions between pets and owners release oxytocin, reducing stress levels, lowering blood pressure, and improving stress resiliency for both parties. Those longer-term lines of research have also found that bonds with companion animals can decrease loneliness, anxiety and depression while promoting physical activity and social connections.

Breed differences also appear in published research: different dog breeds exhibit varying emotional intelligence and responses to human emotions, with breeds like Golden Retrievers, Border Collies, and Cavalier King Charles Spaniels showing superior abilities to read and react to owners’ emotional cues. How do different breeds of dogs respond to emotional stimuli from their owners? Such findings help explain why individual animals may respond differently in short observational projects.

On the question of how widespread strong emotional bonds are between owners and pets, the Canine Cottages report does not offer survey data. Surveys indicate many pet owners view pets as companions, though specific joint APA/AVMA polling on ‘two-thirds’ for dogs not confirmed. For example, joint polling reported by the American Psychiatric Association and the American Veterinary Medical Association has found that roughly two-thirds of pet owners view their pets as sources of companionship.

The Canine Cottages release adds to a steady stream of public interest stories about the ways people and dogs communicate. The company’s monitoring approach — collars worn continuously for 168 hours with noted interaction types — produced the headline figure that has circulated widely online, but the limited sample and the reporting format mean the result should be read as an anecdotal observation rather than definitive evidence.

For readers interested in a fuller summary of research on pets and human health, outlets such as Harvard Magazine have reviewed longer-term studies on the health and emotional benefits that can flow from positive interactions between people and animals.
