Hi everyone. I am new to this forum. I am a third year university student studying applied zoology and wondered if a few of you may be able to help me. I have an assignment on morphology and I have decided to base it on back lengths in relation to coat sizing. I came up with this because I really struggle to find coats to fit my JRT, according to the sizes on the coats she should be a small but a small absolutely drowns her. I can't be the only person with this problem? If anyone is will to help I would be so great fun it will only take minutes. I will post instructions below with an image that can act as a guide. Thank you so much in advance. Using a tape measure, measure the length of your dogs back from the nape of the neck to the base of the tail in cm's. Please respond to this thread with measurement, age and gender. Thanks so much for helping me compete my study.
