Q & A From the Breeding Survey – Kinked Tails causes of?

Some of our readers, who have completed our Breeding Survey, have posted questions which we will research and hope to answer. Thank you to those who have already completed the survey and shared questions with us!

One of the questions posted was:

“One puppy in each litter born with kinked tail; I would like to find out, if possible, if this is due to the womb environment or to a genetic factor.”

Puppy born with a kinked tail. Sometimes these involve only the very tip of the tail but can be even more obvious as shown in this photo.

An article we published in January answers that question and we believe you will find it helpful! Simply click on the following title to be taken to The Kinked Tail – More Than it Appears. 

Readers did you know you can search for information on Gordon Setter Expert by clicking the little magnifying glass on the top left hand bar of the site opening a search text field. Or you can search for articles by their general topic by clicking on any of the categories found on the sidebar columns. Scroll down the page once your category opens to find all articles currently published on that topic. Categories include topics like Breeding, Care (feeding, grooming etc.) Dog shows, Performance events, etc.

GORDON BREEDERS WE NEED YOU:  We have created a very quick online survey for Gordon Setter breeders that will help us learn what, if any, issues you may have encountered in producing quality litters. We are preparing for an upcoming seminar on reproduction and need your input in order to prepare topics that would be most relevant to you. Please take one minute to link to the survey only if you own a bitch or bitches you have bred or attempted to breed in the past 5 years. The survey is completely anonymous.

This link when clicked will take you directly to the survey’s 8 easy questions.


The Kinked Tail – More Than It Appears

It’s not life threatening, it only happens occasionally, it doesn’t make them sick and it can easily be remedied with a quick and relatively painless surgery while they’re still babies. Sounds pretty harmless, nothing to be worried about or to take too seriously…or is it?

Over the years I’ve been privy to a few conversations among Gordon Setter people about puppies born with a kink in their tail. I once heard someone say that the puppy’s tail was kinked because it was a huge litter and the puppy was crowded in the uterus, so the tail didn’t have room to grow properly….really? Another time I heard it said that the bitch was crazy wild while she was pregnant and her rough-housing probably broke the tail before the pup was born and the tail healed wrong…uhmmm no.

So, understanding that there may be folks who don’t understand this phenomenon I thought I’d put a little something out here as food for thought. The best article on the topic that I’ve found so far was written by Ms MA J.H.C. Brooijmans-SchallenbergThe Kink in the Tail“.   “If we wish our pedigree dogs to have good futures, we will need to step up and take our collective responsibility for it.”  OLYMPUS DIGITAL CAMERAI’d advise you to read the article in full, I am not an expert and cannot be responsible for fully explaining everything in as much detail. I will only attempt a brief summary to get you started.

The tail is an extension of the spinal column, which consists of vertebrae that are built differently depending on their function. Congenital aberrations of the tail shape can be found in many animals including the dog, and these generally cause no issue as long as the defect is only found on the tail. The warning is that breeding these affected dogs can result in offspring with serious defects in other parts of the body.

Starting with the fertilized egg three germ layers are formed, the most important layer, the Mesoderm is where the entire skeleton (excluding the crown of the skull), the heart, the blood vessels and the urogenital system are shaped. In the early stages of the embryonic development a great number of genetic factors pass on their information. Mutations occur often, and when they occur in the reproductive cells the changes are transferable to descendents.

As a result, there are many things (other than simply a kinked tail) that could be transferred to the offspring if Gordon Setters with kinked tails are used in breeding, and this is due to the formation of not only the skeleton, but also the heart, blood vessels and urogenital systems in the same layer, the Mesoderm. For example the offspring could have defects in the spinal column or any other part of the skeleton and jaw. Perhaps the defect could be an aortic atrium septum (undersized septum in the heart) or aortic stenosis (aorta too narrow in places), or the embryonic blood vessels fail to disappear after birth. Another defect could occur involving urethra running from kidney to bladder that is not implanted in the bladder past the sphincter. Females with this abnormality often display incontinent behavior. Males have two sphincters so this defect could be present but not evident. This is a very short list of the many abnormalities that can occur.

The Gordon Setter Health Survey conducted in 2004 for the Gordon Setter Club of America Inc. reported that 6.06% of the total population survey reported Kinked Tails under Musculoskeletal health problems. Certainly not a huge portion of the population but it does indicate to us as breeders that this occurs in the Gordon Setter. As breeders, I hope I’ve helped you gain a better understanding of what could be at play and the risk. I do hope our readers  and others who may be much more expert on this topic than I, will share your thoughts, additions or additional information in the comment section below!
