Abstract Objective The first aim was to describe the incidence and severity of surgical complications following peripheral lymphadenectomy in dogs. second compare three techniques: unassisted lymphadenectomy, intraoperative guidance by methylene blue dye alone (MB) or a combination γ‐probe MB (γ‐MB). third assess whether number, palpability, site lymph nodes (LNs) influenced complications. Study design Retrospective multicenter study. Sample population Lymphadenectomies ( n = 201) from 163 client‐owned tumor‐bearing Methods Medical records dogs undergoing both preoperative sentinel LN (SLN) mapping excision SLNs between December 2020 April 2023 were reviewed. Signalment, assistance technique, number LNs, time, postoperative treatments, site, timing observed collected. Results Seventy‐two (36%) lymphadenectomies performed without assistance, 24% with 40% γ‐MB. overall 7.5%, which 80% mild. most frequent complication seroma (2.5%). None variables considered logistic regression model, including guidance, rate p .255). Using decision tree statistical mandibular retropharyngeal affected when surgery lasted more than 21.5 min. Conclusion Lymphadenectomy LNs associated low mild complications, regardless assistance. Mandibular lasting min may result Clinical significance superficial is safe procedure that easy perform cases, even
