Hypothyroidism is pretty common in any hairy breed, the amount of hair grown puts a strain on the thyroid, EPI, is Exochrine Pancheatic insufficiency, according to the breed club, it's not a common recognised condition, but both my dogs are from completely different lines, breeders etc, and both have it, frankly as far as I'm concerned that speaks volumes. The neck thing is because of the people I got my girl from as a 2 yr old thought it was funny to rest their feet on her when she stood in front of them so she has been left with two slipped discs
The ruptured crutiate ligament in my boy that resulted in the TPLO op was because he's a mad lad, that hares about, and put his foot down a hole over stretched the ligament when he was in the dog park!!
However because I have insurance, both of my dogs live VERY healthy happy lifes, they take daily medication, and their conditions are kept completely under control thankfully. THat and having a vet that works with me, rather than simply for me makes the world of difference too
I can honestly say if you were to meet my dogs you wouldn't know there was anything wrong with them
