公部門一直扮演掌管棄犬問題處理的角色，業務包含捕捉、收容、安樂死、認、領養等等，然而公部門一些不當處理棄犬的手段，也引起民眾與動物保護團體的關心甚至抗議；近年來非營利性的動物保護團體蓬勃發展，其擔任教育民眾愛護動物與政府積極協商的角色，展現出的企圖心與活動力一再凸顯出貢獻與重要性。隨著時代變遷及價值觀的轉變，各動物保護團體的發展方向、專業能力、重點工作、政策監督與義工訓練也隨之有了轉變，使得民間團體與政府的對話空間、承辦計畫往來逐漸熱絡頻繁。據此本研究之目的有四：一、瞭解公、私部門處理棄犬問題的差異性；二、分析公私協力互動模式；三、公私部門同質性組織互動關係；四、理論與實務之印證。 本研究採取的研究方法為文獻分析法、參與觀察及深度訪談法。首先文獻分析法乃經由公私協力相關理論、國內外碩士論文與期刊、官方與民間網站、報紙蒐集分析、相關法律條文等回顧，對於理論與個案做一綜合性分析。其次參與觀察法乃研究者選擇參與中央與地方政府舉辦之座談會、擔任民間動物保護團體之義工、棄犬相關之公聽會、研習會、教育訓練營等活動，透過個人參與之觀察以利對個案重大議題之瞭解。最後深度訪談法方面係以半結構型的訪談類型為研究標準，根據文獻分析與參與觀察而設計出三個脈絡：一、源頭管製法律面；二、棄犬捕捉執行面；三、收容管理面，以聚集利害關係人關切之焦點。 本研究分析從源頭管製法律、棄犬執行以及收容管理等三大脈絡作為主要架構，配合訪談綱要的提問以及多數受訪者提出相關策略議題構築成的對話空間，延展出十三項策略，並適時列舉受訪者的關鍵論點以說明其態度與立場，並進階探索受訪者的動機與背景或爭議內容的呈現。最後呈現公私協力的模式與結果，並萃取各策略所支持的個案研究之概念化成果。
The public sector always plays dealing with stray dogs'' problems roles whose affairs including catching, sheltering, euthanasia, claiming etc., and then whose action has been taken care even remonstrated by animal welfare organizations. On the other side, non profit animal organizations having show attempt, activities and always emphasizing their contribution and significance have developed in recent years which play roles in educating citizens and negotiating with government. As times goes by , values have also been changed. Each animal welfare organization has changed its developed direction, specialized field, main mission, policy monitoring, and volunteer training. Whose make NPOs and government's dialogs together and handle plans more common. According to this, I have four proposes: first, to realize the difference between public and private sectors in dealing the strays' problems. Second, to analysis the public and private sectors interaction models. Third, to understand the public and private sectors interaction by each other. Fourth, to examine the theories and the case study. The research has been adopted by literature review, participant observation and in-depth interview. In literature review, I have selected about public-private partnership theories, theses and journals internally and overseas, official and civil websites, newspapers review, law review to integrate the theories and the case. In participant observation, realizing the case study, I have joined some symposiums held by the center and local governments and taken on some animal protection organizations' volunteer, joined public hearings, rap sessions etc. In-depth interview, I used semi-structured interview. According to the first two research methods, I gathering the foci of the stakeholders' concern have designed three skeletons: the source regulation laws, the stray dogs catching enforcement, and the sheltering management. With the three skeletons of above, after interviewing, I have tried to expand thirteen strategies and lined some interview's crucial arguments timely to explain their attitudes and standpoints, even explored interview's motivation, backgroud, and presented their disputes. At last appearing the conclusion of public-private partnership, I have extracted the conceptualized effects in case study been supported by each strategy.
