Brief Summary
The purpose of this study is to evaluate the effectiveness and medium-term maintenance of a structured dog-assisted therapy (DAT) protocol, "Entre Patas e Afetos" (Between Paws and Affections), in reducing pain, anxiety and depressive symptoms and in improving functional status and quality of life in Portuguese patients with fibromyalgia (FM) followed at ULS Alto Ave, with systematic outcome assessment in the immediate post intervention phase (T2), 6-month follow-up (T3) and 12-month follow-up (T4).

Outcome Measures
Primary Outcomes (2)
Pain intensity (maximum and average) and pain interference
Measured by the Portuguese Brief Pain Inventory - Short Form , at T2 (post session 4), T3 (6 month follow up) and T4 (12 month follow up), to capture both short term change and medium term maintenance at 6 and 12 months after the first month (T2). Self reported pain intensity using a Numeric Rating Scale with faces / adapted Wong Baker Faces Pain Scale, collected at each session to monitor pain fluctuations across the acute and maintenance phases.
13 months - From 1 month after enrollment to the end of treatment at 12 months after the first month
Fibromyalgia impact and functional status
Measured by the Portuguese Fibromyalgia Impact Questionnaire (FIQ P), at T2, T3 and T4, allowing evaluation of functional changes and their persistence at 6 and 12 months after the first month (T2)
13 months - From 1 month after enrollment to the end of treatment at 12 months after the first month
Secondary Outcomes (2)
Anxiety and depressive symptoms
13 months - From 1 month after enrollment to the end of treatment at 12 months after the first month
Pain catastrophizing
13 months - From 1 month after enrollment to the end of treatment at 12 months after the first month
Study Arms (2)
Behavioral: Dog Assisted Therapy (DAT - "Between Paws and Affections")
EXPERIMENTALIntervention group that will receive a total of 10 group sessions at the Psychiatry Day Hospital of ULS Alto Ave, organized into 4 weekly structured sessions (combining psychoeducation on fibromyalgia and chronic pain, functional training and self care, lifestyle counseling and guided relaxation, all mediated by trained therapy dogs and a professional dog handler), followed by 6 monthly guided relaxation "booster" sessions with the dogs.
Behavioral: Psychoeducation and Relaxation without Dogs (Control)
ACTIVE COMPARATORNew active control group that will receive the same 10-session program, with structure, duration, and content identical to the DAT arm (4 weekly structured psychoeducation and functional/self-care sessions plus 6 monthly guided relaxation "booster" sessions), but delivered entirely without dogs.
