Sit PrettySee the picture… this is what we’re talking about.  Teaching your dog to do this is all the rage in canine sporting groups, training groups, and trick groups.  People have been told that it’s a good exercise for building “the core”.  And while it might just get your dog to activate his or her abdominal muscles, it might also be doing damage as well. 


It has been 13 years since I first saw this exercise described and promoted, and at the time, my gut feeling was that I didn’t like it.  But I didn’t know why.  Over the last 13 years, I’ve come across research that has helped to reinforce why it might not be the best exercise.  It’s taken me this long to think about it, compile some evidence to support my thoughts, and because I was asked to write out my rationale by a colleague, only now am I speaking out in a very public forum.


I do not recommend ‘Sit Pretty’ as an exercise.  Here’s why:


1. It’s not functional.  When is this skill needed in a dog?  Does is translate to any other functional movement?  Do we actually know that it builds core muscles?

Answers:  Never.  No.  No.

So, those who are promoting and loving this exercise are doing so based on hearsay or just because they’ve seen others doing it and are looking for something to add to their dog’s training regimen or trick roster.


2. What happens to the facet joints during ‘sit pretty’?  The facet joints are the joints of the spine that control movement.  With the exception of the first two vertebras, each other vertebra is joined to the vertebra above or below it (or ahead or behind, in the case of 4-legged creatures) by a set of facet joints as well as the disc.  The facet joints transfer load, allow for movement, and also block undesirable movement (1,3). 

Firstly, let’s realize that the facet joints in the dog’s back are designed to transfer forces from limbs to the body / spine with the dog in ‘normal dog positions’ (sitting, standing, lying down, and moving directionally).  When a dog is in a ‘sit pretty’ position, there are 180 Newtons of force going through the facet joints (2). Compare that to normal walking (approximately 107 Newtons) or standing (approximately 26 Newtons).  Walking upstairs comes close at 170 Newtons, but standing erect on two-legs exerts the greatest amount of force through the facet joints.  Surely there’s no benefit to that!


3. The consequence of making facets do what they’re not intended to do.1 It has been reported that when a dog has more extension forces on their back that their bodies will adapt by smoothing out the joint surfaces that are being bashed together.  In quadrupeds, it’s the facet joints that get smoothed out and enlarged, allowing more slip and slide of the joints in extension.  This protects the back from painful bashing… but it also serves to de-stabilize the spine.  Essentially, the joints are no longer blocking movement, they are now allowing more movement as an adaptation of what is being asked of the body.  It might sound like a good short term solution.  However, when this occurs it also means the more stresses and forces go through structures that shouldn’t be stressed further (i.e. the disc, or the muscles, or small local ligaments), and when this happens, the body needs to come up with another way to stabilize the area.  How the body does this is by adding bone to try and stabilize (otherwise known as spondylosis).  Spondylosis is when a bridge of bone is formed between each vertebra on the underside of the vertebra.  While I tell people not get freaked out about the presence of spondylosis (i.e. their dog is not crippled or paralyzed by its presence) it does mean that there is an area of the back that has become overly stiff, and subsequently, a different area of the back is likely becoming too flexible to compensate.  And neither is ‘great’!


4. The iliolumbar ligament (3). Who?  Maybe you’ve never heard of it.  Your dog hasn’t… because he/she doesn’t have one!  The iliolumbar ligament is found in people.  It’s a strong ligament that helps to stabilize the lumbosacral junction6 (basically the junction between the low back and the pelvis / tail bone).  It is a ligament that is likely found in people and not in 4-legged animals because as 2-legged creatures we need more stabilizing mechanisms to help us stay upright!  It is thought that the muscle Quadratus Lumborum is what helps stabilize the spine of quadrupeds in the absence of the iliolumbar ligament (5). But this is a pretty thin, small muscle in dogs, so it’s not likely to be providing the same stability that a strong ligament can!


5. More missing ligaments!  An interesting study was conducted looking at the ligaments of quadrupeds (i.e. dogs / horses / rodents), bipeds (humans), and pseudobipeds (birds) (4). The researchers found that a set of ligaments (to the side of the vertebra in the thoracic spine) were absent in any of the quadrupeds they studied.  They speculated that these additional ligaments were a development subsequent to the mechanical challenges unique to having an erect spine.  They also discussed how developmental scoliosis was not a typical problem in quadrupeds, but is a more common occurrence in humans and birds. 


Essentially, being upright is associated with high facet joint forces, a higher incidence of scoliosis, and the need for additional ligaments. Dogs are not designed for time spent in an erect posture. (Nor are goats, horses, or pigs… in case you were wondering!)  All in all, I can find no redeeming qualities in the Sit Pretty exercise.  As such, my professional recommendation is to just stop it, and your dog will be better off for it!

Why do people want to love this exercise so much?  The article above has created quite a firestorm!  I posted it on my clinic’s blog page and it was re-shared on a big Facebook group for people interested in conditioning their dogs (Canine Conditioning and Body Work – private group, but anyone can ask to join).  I’m surprised I’ve not gotten death threats from it!  There are people saying that my opinion isn’t researched or validated, saying that their dog does it and doesn’t have back problems, saying that they were told it was the best exercise for their dog’s ‘core’ and if they trained it, it would add 2 years to their life (no joke, someone told me that they were told that in a seminar!), saying that my opinion has no credibility, saying that I am an ‘old fashioned vet’ (Really?  When did I become old or a vet?), saying that because I have this opinion, I must not be in favour of any dog-sports or exercise of any kind, saying that I should have published a research paper if I wanted to express this opinion, and a whole host of other nastier, evil comments.  And despite all of the negative comments, I’ve also had hundreds of comments, e-mails, and messages saying ‘Thank you for writing this Laurie, I always felt uncomfortable with this exercise.’


So, I thought, if you want flat out un-researched OPINION and CONJECTURE, I might as well continue this article then! 

Part 2, why I hate the Sit Pretty (and Stand from Sit Pretty) exercise.  

Here goes!

A. There is not one shred of evidence out there that validates Sit Pretty as an exercise that works the core.    Sitting and standing erect have not helped humans develop a strong core, why would we think it would do so in dogs?  PLANK!  Now there’s an exercise that works the core… but that’s for another blog.  Now, if your knees aren’t total garbage, I want you to try this yourself.  Squat down, feet hip distance apart, and “make sure your back is straight upright”.  Firstly, your tendency is to lean forwards, why?  Because in order to be balanced, you want your body weight to be distributed over your base of support (i.e. between your feet).  But when you straighten your back (you are using your spinal extensor muscles).  Try to get really straight and tall, you’ll be inclined to throw your arms out in front of you (again to shift your body weight forwards so it’s over your feet (and not behind your feet/heels). The other thing that happens is that you hyperextend in your lumbar spine to throw your weight forwards slightly (in order to get your back straight).  And the lumbosacral junction in dogs in particular is very prone to lumbosacral injury.  It doesn’t do well with repeated hyperextension.  When I try it, I feel my back hyperextending as my weight shifts backwards, and I have to try to correct to bring my weight forwards again (and maybe my abdominal flicker on to help me go forwards, along with the waving of my arms)… but it starts to get very uncomfortable on my back after a while.  Maybe you won’t see the repercussions of this exercise now, but maybe when your dog is 10 – 14 years, you will!  Or not!  But then again, there was a time when smoking was considered harmless too!  My Dad was a chain smoker for almost all of his life, he’s still alive at 75, so it must not have harmed him, and should be okay for anyone else wanting to take up the habit. Margarine used to be considered healthier than butter… Helmets were only introduced into hockey in 1974… and I remember riding in the backseat of the car without a seat belt growing up.  Maybe we should have fought harder against changing ways back then too?  (Please, oh please, note the sarcasm here!)  


B. How is Sit Pretty a conditioning exercise?  What are you conditioning for?  The SAID principle of conditioning says that “when stressors are imparted on the body, whether biomechanical or neurological, there will be a Specific Adaptation to Imposed Demands (SAID).  For example, by only doing pull-ups on the same regular pull-up bar, your body becomes adapted to this specific physical demand, but not necessarily adapted to other climbing patterns or environments.” ( We also know that being able to do hundreds of sit ups as a person, does not mean you have good core stability when it comes to functional activities and movements.  So, what is it you might want to accomplish with Sit Pretty?  What does it lead to?  How is it a functional exercise, and what does it actually improve in a performance dog?  Will it help a dog to jump over a jump or for a police dog to scale a wall?  When choosing a starting position from which to explode forwards or upwards, I would argue that no dog goes into a ‘sit pretty’ and then explodes out of it.  They will lean their weight onto their rear limbs, but their body is never vertical before they burst (nor should it be)!  So, I’m going to say, it’s nothing more than a trick.  It’s not a true conditioning exercise.


C. When a dog stands up on both rear legs (i.e. looking over the fence or ‘dancing’), then yes, there is an increased loading on the facet joints as discussed in the first section of this blog, and yes, it’s only slightly more than climbing stairs.  However, as I discussed in point A, the load in sit pretty may alter the extension forces on the spine, and while my upcoming viewpoint has not been researched by science, I HYPOTHESIZE that the joint forces for sit pretty are even higher than in standing erect.  When standing erect, a dog can move his/her hind legs backwards and balance the bodyweight more directly over the feet (i.e. the base of support for the dog).  This is going to enable the task to be done more successfully and with better balance.  And often you will see dogs offer this over a ‘proper’ Sit Pretty, I think that means something.  As well, when people say, meerkats, gophers, and rats do this, and so does my little dog, I think you’ll see that they are actually standing on the rear legs, not ‘sitting pretty’ (unless they were taught it and rewarded for doing it at some point in time).


D. Facets and ligaments, why am I focusing there? I have focused my discussion on these factors because this is where there is evidence, and as a professional, I should be using the best available evidence to back up my clinical impressions and decision making.  There are likely forces on the discs that are unnatural with Sit Pretty as well.    Over extending in the lumbosacral junction is a real problem in working dogs of all types. Agreed.  But if this exercise doesn’t help that, and possible adds to it, they why be so adamant about doing it?  And yes, muscles are so important for stability, not just ligaments, but to dismiss the importance of the absence of two spinal ligamentous structures in quadrupeds as compared to bipeds is simply burying one’s head in the sand.


E. Squats from a Sit Pretty… I dislike this even more!  When it comes to this exercise, I think it’s the stifle joints that are being put at risk.  A dog’s stifle joint has more of a slope to the tibial plateau, and this in part is one of the proposed THEORIES as to why dogs tend to develop cruciate DISEASE (not just traumatic tears, but degeneration of the ligament over time, leading to a failure of the ligament with a somewhat innocuous movement one day).  So, if a stifle is not a ‘knee’, then why make a stifle flex and extend while taking full body weight in an unnatural position?  And yes, we could discuss the mechanics of the back getting in and out of the sit pretty, but I think the biomechanics at the stifle makes a stronger argument here.  HOWEVER, if you want to put the dog’s front feet up on a stool, step, ball, platform, etc. so that he/she is leaning forwards and ask for a stand, and then back down into a sit, that is a much more natural movement for the stifle (like climbing stairs or a hill or preparing for a jump) and is therefore a functional exercise.  (And yes, is should be about function!)


Beyond these points, I’d like to add that when we are choosing to do or not to do something (exercise, therapy, technique, etc.), we try to be as ‘evidence informed’ as possible.  If we were waiting for research to tell us what to do, well then nobody would be conditioning dogs at all… since there’s no evidence to back that up! However, when trying to decide what to do (in whatever situation) you use the ‘best available research’ to make an ‘informed decision’.  And that’s what I’ve done in presenting my argument.  I only ask that people take the time to stop and think about the arguments presenting without getting immediately defensive (and nasty).  One of my Facebook friends had summed it up with “When we know better, we do better!”  


Be sure to address the letter bombs directly to me, I’d hate for one of my staff members to be blown up for no good reason!   

Cheers, Laurie
