Wow, thanks so much everyone, this is a brilliant help.

Elbow dysplasia is something I've not seen too much of either. I have seen a luxation of the elbow joint in a labrador cross, but I don't think it's quite the same. Correct me if I'm wrong there.

I would also assume that hip and elbow conditions would go hand in hand, as if weight distribution is affecting the hind limbs then it seems likely that the forelimbs will be experiencing similar problems.

About 8.75% have Coloboma's which is a small pit or bulged in the eye and about 1.8% have Retinal Detachment.
I have read a little about CH, this is the condition, I think, where the tissues between the retina and sclera don't form properly? I've never come across CEA before though. I have seen two cases of colobomas before, one fairly serious and the other not quite so.

Karen, I'm so sorry to hear about Logan's hips, poor girl. This may sound silly, but what exactly about her gait did you notice? Not having come across the condition a lot and not having owned a dog before, I'm a little green when it comes to spotting these things.

Also the point about the length of sternum is very interesting, I'll have to research that a bit further. I'd only ever really thought about the cranium, spine and joints being the areas of skeletal disorders before.

Infection took her life in the form of Pyrometra. All we could try was antibiotics as she would not have been able to handle the other treatments. We didn't have her spayed due to the higher risk with that surgery.
Zara, if you're interested, just ask for more info and good luck.
Here's a link about SAS...

Thanks for the link, and I'm so sorry that sweet Mandy had this condition. This is also a condition I've remotely heard of but not really experienced. So the narrowing of the aorta (I think stenosis is to do with narrowing?) brings on the murmur? The only murmurs I have ever encountered were to do with leaky valves.

The conditions I've come across most often are in the short-nosed breeds; cleft palates, elongated soft palates and bronchial or tracheal collapse. I also recently witnessed a bulldog caesarian (I'm under the impression that a lot of bulldogs can no longer give birth naturlly due to the breed standards demand for such huge heads) and it was so disheartening when two puppies were born cleft and the breeder requested their destruction. Such a waste.

Does anyone have any further knowledge on these conditions?
