Profile of Dogs’ Breeders and Their Considerations on Female Reproduction, Maternal Care and the Peripartum Stress—An International Survey
Round 1
Reviewer 1 Report
This MS is to understand the factors considered important in relation to reproduction, maternal behaviour, and the peripartum stress in bitches and demographics of breeders from different countries. The objectives are within the scope of the journal. However, various issues should be fixed:
1-First, the title needs to be modified. Please modify. "the peripartum stress" would be better in the title.
2-Introduction section is very long and not relevant to the main objectives of the study. The authors should present the rationale of the study (why the authors did this study?)
3-Statistical analyses need to be described in details (type of statistical assay, parameters such as nonparametric tests ;chi square, .....). In addition, the significance should be indicated in the figures.
4-Different parameters in the investigation should be indicated as an illustrating chart in the material and methods section.
5-Environmental factors and effect of seasonality were not indicated in this study. The authors should highlight these factors. Otherwise, it should be indicated in the limitations section.

Dear Reviewer,
Thank you for the time and effort to review our article. We appreciate your comments and suggestions. We believe that your feedback improved our manuscript. We have incorporated most of the suggestions and only one request was not addressed as described below.
1-First, the title needs to be modified. Please modify. "the peripartum stress" would be better in the title. Done
2-Introduction section is very long and not relevant to the main objectives of the study. The authors should present the rationale of the study (why the authors did this study?) The suggestion was addressed and the introduction was rephrased to better adapt to the objectives of the study.
3-Statistical analyses need to be described in details (type of statistical assay, parameters such as nonparametric tests ;chi square, .....). In addition, the significance should be indicated in the figures. The suggestions were also addressed, however for the p values in the figures; it would not be relevant since the comparison amongst countries was always done two by two.
4-Different parameters in the investigation should be indicated as an illustrating chart in the material and methods section. Done
5-Environmental factors and effect of seasonality were not indicated in this study. The authors should highlight these factors. Otherwise, it should be indicated in the limitations section. Done

Reviewer 2 Report
Interesting article about dog breeders and the influence of the breeding facility on stress and maternal care. It also describes trends in current dog breeding.
I miss the row numbers in the manuscript. It would be much easier to point the exact part of the article.
Page 3, 2nd paragraph- there is a duplication in the sentence after citation 24 "... the shortage of puppies in the UK due to shortage of puppies..."
In figure 1 and 2, page 6 and 7, there are switched captions of the graph axes.
Part 3 Results: as a part of the Results, there is a chapter "4. Management, signs of stress and .....". It should follow the numbering of chapters so it should be "3.4." and the following chapter "4.1 Signs of stress.." should be "3.4.1". Same with the chapter 4.2, it should be "3.4.2". Discussion should be 4, not 5. etc.
I suggest to check the formatting of the text and unify all the fonts etc.
Authors summarize the limitations of this study by themselves very well. I think that it perfectly points out the need of further research in this field to obtain valuable data that could be applied worldwide. At the same time, it also stresses the importance of smaller studies on local scale to find out differences between breeding practices in different countries.

Reviewer 3 Report
This study describes the usual behaviour and breeding methods of dog breeders, throughout an international survey. The manuscript is interesting and innovative and has a good study design. It might be interesting for the reader, therefore, in my opinion, it needs only minor revisions. English language is good and easily readable, but a check is needed in order to find and correct some errors.
It was difficult to review this manuscript because of the lack of line numbering. I try to list my revisions dividing them in sections and when the section was too long in paragraphs, according to the divisions made by the authors in the manuscript.

- Please delete (puppies)
Paragraph 2
- “This overrepresentation of large kennels in these two countries is most likely to be totally random and could be explained by the simple fact that owners of large kennels took the time to answer the survey more than those from other countries. Nevertheless, in Brazil, there is still no federal law that prohibits or regulates the sale of pets in pet shops, nor the commercial breeding of pets what could favor the presence of large kennels. Specific government laws were introduced in the last couple of years in the other represented countries and perhaps a tight control could affect the size of dog breeding facilities. Con-tradictorily, although in recent years there was an attempt to control puppy farms; dog breeding in the USA was qualified in 2017 as a big business with little governmental oversight [49] and no dog breeders described in this study the activity as their main source of income. In terms of breeds, the representation of dog groups in in our sample was in accordance with the popularity of different breeds worldwide.” This part seems to be not really clear, please could the authors try to clearly explain why this finding of this overrepresentation of large kennels in these two countries could be totally random?
Paragraph 3
- “breeders of Portugal declared lower levels of interaction compared to USA/Canada (p=0.0299), Germany (p=0.0019), the UK (p=0.0028) and Poland (p=0.0251) and from breeders of Australia in contrast to Germany (p=0.0091) and the UK (p=0.0144).” please rephrase
Paragraph 4
- “Portugal (use of a teaser male)”, use of teaser male was the most common technique used in Portugal?
- “(p=0.008)” please delete if already mentioned in the result section. Please check it throughout the discussion section.
- “Although vaginal electrical impedance has been the subject of different studies to evaluate its efficacy in predicting breeding time, this method was barely listed by breeders.” Please add citations to this sentence.
Paragraph 5
- “However, it was applied indirectly when breeders cited the measurement of temperature of the bitch at the end of pregnancy since this corresponds with the drop of progesterone.” Please explain what is the thought of the authors about he use of rectal temperature instead of serum progesterone, taking into account the sensibility and specificity of these two different parameters.
Paragraph 6
- “is reviewed” please modify in “has been reviewed”
Paragraph 7
- Lines 3-4: please rephrase this sentence.
Paragraph 9
- “breeders (all countries together)” please modify in “all the interviewed breeders”
Limitations
- “savvy” is too informal, please change with a synonym
- “Therefore, we strongly believe the results..” please modify in “Therefore, we strongly believe that the results..”
- “Key Opinion Leaders”, why the authors used capital letters?
- “specific breed”: this may influence for example answers about the prediction of parturition day and pregnancy monitoring if the breed is a brachycephalic one and if it requires a planned C-section. If possible, consider also this point.
Conclusion
- “around whelping time (prior and after)” please consider to modify in “in the peripartum period”
- “the more it will” please modify in “the more this will”
- “and therefore animal welfare” please modify in “and therefore on animal welfare”

Reviewer 4 Report
The paper presents the results of a survey intended to study the demographics of dog breeders and to seize their perception and practices about reproduction, maternal behavior and management of the dam-during the peripartum period.
The data presented are numerous, some of which are not very interesting (for example the specific techniques used to estimate breeding). It would have been useful to know the cultural level of the breeders and if they have taken courses in dog biology, ethology and genetics. Unfortunately, cases of "genetic maltreatment" with the birth of animals carrying hereditary defects are more and more frequent.
It would also have been useful to try to understand if altered behavior at delivery or the stress signs are related to the breeding methods.
Overall, the paper is interesting for the large number of data it proposes, even if a more critical approach would have been appreciated.
I believe it can be accepted for publication

Dear Reviewer,
Thank you for the time and effort to review our article. We appreciate your valuable comments. Indeed, some important issues were not addressed in the survey. We were conscious of this constraint but the survey used was initially run in France and we wanted to have the possibility to compare the results. We reduced the introduction and added some more critical discussion over some points. We hope these modifications improved the current version, in order to have a better chance to publish the article. Once again, thank you for your time and comments.
