Indeed, studies show that the quality of mothering is not only important for the survival of the puppies during the first weeks of life, for the bonding process but recently it shows that it might have a long-lasting impact on the puppies’ future performance. However, how to define and measure maternal behavior? From the early studies to nowadays, the display of acts from the bitch right prior to parturition (preparation phase), and then continuously toward the puppies until weaning are the repertoire of actions that define maternal behavior. For the scientific community, maternal care is quantified as a principal component assessing attitudes that are easy to measure from the dam to the puppies such as: the time spent in contact, time and/or frequency of licking/grooming and time and position of nursing. Though, there is still a need to elucidate different aspects of maternal behavior in the dog, for example the effect of genetics, the impact of the emotional state of the bitch and the quality of maternal behavior, the role of hormones, the possibility to improve maternal behavior, there is some information to share. The idea is to give an overview of maternal behavior that permits veterinarians, breeders to identify and prevent problems to optimize the dog welfare.","PeriodicalId":153636,"journal":{"name":"Revista Brasileira de Reprodução Animal","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115857177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

What we currently know is minimal compared to the large number of species that remain unstudied. In addition to the impressive diversity of natural mechanisms, other complexities limit the progress of wildlife reproductive science little interest in animal reproduction, difficult access to animals, lack of expertise, hard working conditions, and insufficient funding. Despite those challenges, some species are being saved from extinction with the help of a precise understanding of reproduction, development of assisted reproductive technologies, and creations of cryo-banks. Those advances originate from huge progresses in non-invasive measurements of steroid metabolites in urine or fecal samples to study and monitor reproductive functions and pregnancies. Progresses in cryobiology also have been impactful in animal conservation. Importantly, emerging technologies (transcriptomics, microfluidics) and additional research areas (reproductive aging, microbiomes) could lead to more successes and address current challenges in the reproduction of rare and endangered species. However, while some emerging approaches like stem cell technologies may sound promising, it is necessary to design holistic strategies considering all available tools to optimize investments, time, and efforts in conservation.","PeriodicalId":153636,"journal":{"name":"Revista Brasileira de Reprodução Animal","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128881062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
