My name is Rebecca Sumner and I am undertaking my PhD in veterinary medicine and science at the University of Nottingham. This study expands my current research into male fertility and is part of Nottingham’s breeder research programme. 

Current research suggests that factors in the environment negatively affect reproductive health and fertility in the male dog, particularly when the pup is developing in the mothers’ womb and for a short period after birth. This survey is designed to investigate how the environment might influence pups both before and after birth, with particular emphasis on the mother and male pup. We are particularly interested in looking for evidence of an increase or decrease in the number of pups with one or both testicles retained (Cryptorchid dogs).

There are 2 short sections to this survey. Section A investigates the general environment of the breeding bitches; Section B focuses on the pregnant bitch and subsequent litters. The information provided by you in this questionnaire will be used for research purposes only. All responses are kept strictly anonymous and individual responses are non identifiable. 

I would like to thank you for your time taking part in this study, by providing this data you are helping us to better understand and improve canine fertility. 

The questionnaire should not take more than 10 minutes to complete, subject to the number of litters you have information for.

If you have any questions about any aspect of this study, please do not hesitate to contact me via

Once again thank you for your time. 

Yours faithfully,
