Regular physical activity and balanced nutrition are important in maintaining a healthy weight. Nonetheless, minority populations, like Hispanics, face challenges (e.g., language barriers and transportation unavailability) that limit their participation in intervention programs to receive benefits. Furthermore, dog companionship has been shown to relate to adolescents' behavioral and socio-emotional development positively, and it has been shown to have the potential to increase physical activity in adolescence. Therefore, this study aimed to examine the feasibility, i.e., program adaptation, limited efficacy, and acceptability, of the two exercise and nutrition education interventions to improve body composition, motivation, and well-being in overweight and obese Hispanic adolescents. This pilot study was a quasi-experimental trial with eight pediatrician-referred participants (M[subscript age] =11.75±1.48) assigned to two parallel arms: (1) BRAVO! and (2) BRAVO!+. Both share identical exercise (24 hours) and nutrition (12 hours) programs centered on the self-determination theory for 12 weeks. The results suggested, first, acceptable attendance (BRAVO! = 56.25%; BRAVO!+ = 64.58%) but poor retention (BRAVO! = 33.33%; BRAVO!+ = 63.63%). Second, the findings suggested promising limited efficacy in BRAVO!+ group, with small but statistically non-significant reductions in participants' BMI (M[subscript baseline] = 33.08±6.13; M[subscript post] = 32.23±6.88; t[3] = 1.633, p = 0.201) and weight (M[subscript baseline] = 78.13±16.22; M[subscript post] = 77.62±17.64; t[3] = 0.485, p = 0.661). In addition, the results suggested high satisfaction and acceptable suitability for both programs and providing important suggestions for the future. In conclusion, our pilot study findings only partially supported the feasibility of the pet-dog-enhanced lifestyle intervention. Although this study found evidence that pet-dog companionship can improve program satisfaction and acceptability of pediatric lifestyle interventions, including a pet-dog in the intervention may contribute to high dropout evidenced in this study.
