Yes sadly my now 4 yo dog had hip displaxia from birth
She always walked funny (back end swinging, twisting legs inwards as she walked, bunny hopping) but being a novice owner I didn't realise. She had surgery for luxatting patella at 10 months but the vet didn't pull her hips up. It wasn't until I saw a physio when she started limping again at 18 months that the bad hips were bought to my attention, they are what caused the LP. She has bilateral hip displaxia and I was told she would be lucky to make 5 years, she seems to be going strong though so I don't think her time is anywhere near up, she is a tuff little bugger. I actually think dogs who are born with HD do better because they live with the pain their whole life they adjust to it better, dogs who develop it later in life probably find it harder to adjust to the constant pain.
There is so much you can do for a HD dog now without even considering surgery. Ie: lots of supplements, physio, chiro, hydrotherapy they can still live a long and happy life. My girl certainly doesn't act like she has bad hips, even on bad days.
Even better for young dogs they have early surgery that can actually reduce the severity of HD. Hopefully Zora doesn't have HD but if she does at least you know nice and early.
How did the radiographs go??
