Of course they could, in reality be blue or gold or even black, like 'that dress'? Do they look the same colour in all lighting? how about outside in daylight?

Ha ha! They are definitely yellow (and more yellow in reality than they appear in the photograph.

Enamel looks normal. No radiographs - not had GA.

It's not actually my case, and I've only seen the dog briefly to take the photos, but I get the impression that it's lifespan sadly may be limited as the owners have declined surgical treatment, although I have seen some do surprisingly well with medical management in the past. I will try to post updates when I can find out more.

A good thought but in the photo they look too smooth and shiny.

Idiosyncratic discolouration of the enamel? I had a friend at school whose two front teeth were that colour. No idea why but it did give endless scope for juvenile nicknames...

It will be interesting to see if the adult dentition is the same colour - is the dog likely to live long?

I don't know where the puppy was bred, but if from a west Wales puppy farm, there's a lot of illegal (Irish) antibiotics floating around, or the bitch may have been given a shot (or several) of oxytet originally dispensed for cattle or sheep.

Puppy was bred by current owner. I haven't met the owners but from what I can gather it seems unlikely that they would be the type to give illegal antibiotics, but you never know....

Can anyone think of any explanation other than tetracyclines?

I have now received a copy of the notes from the previous vets. There is no record of tetracylines being dispensed for either mum or pups. Mum had a short course of synulox starting 3 days post-whelping. The only other recent medications recorded are frontline combo and milbemax, both dispensed (though not clear whether or not administered) around 2 weeks prior to whelping.

It really is quite dramatic in reality, the picture doesn't give a true representation of the colour.

I have now discovered that the pup came to us as a second opinion, and we do not appear to have any previous notes yet (I am chasing that one up). Neither pup nor dam have received tetracyclines from us, but I don't know about elsewhere yet. I am also trying to find out if any of the other puppies in the litter are similarly affected.

He has been scanned today and an extra-hepatic shunt is suspected, but his owners have declined surgery. I suspect I may never get to the bottom of this one, but I will post further if I can get any more information.

Another vote for tetracyclines, but don't tell the owner that. Knowing how crazy some designer dogs are bred to be, you may have breeders demanding "the tablets to give the puppies those pretty teeth"

Maybe the picture doesn't do it justice but they don't look particularly yellow to me just a natural variation as no teeth are perfectly white. But if they are then I'd join the tetracycline crew.

[quote user="Evelyn Barbour-Hill"]my guess is that the dam had a course of tetracycline. [/quote]

I always thought it could happen before permanent teeth erupted ie in puppies [and children]?? ie post partum?

[or in deciduous teeth prepartum]??

All I can find relating to bilirubin refers to human children, and it seems the staining is a horrible green, and only on part of the tooth. For what that's worth. Dogs might be different.

The discoloration in your picture is so beautifully even and bright yellow (it's quite attractive!), my guess is that the dam had a course of tetracycline. But I don't know.

PS It would be cool to find out if they fluoresce in ultra-violet light.

I doubt it's bilirubin as the dentine and enamel in those teeth started forming prenataly. Any chance the dam was given tetracyclines while pregnant? Otherwise no idea, but they sure are yellow!

Tetracyclines?
