Hello everyone - im new here, from Iceland - so i hope my english is readable I have a 9 months old boxer boy named Mökkur. Right before christmas he beginned to be sick. He had a hard time to move, got heat and just wanted to lay down (very unlike himself). I went to the vet and got some painkilllers - she checked him out and took a blood test and everything seemed fine. The next days he got really worse and could not move and whined when he tried to move or when i touched him (i was dying of concerne)- i went again to the vet and the she took another blodd test, rubbed him and took a x-ray of him all. And again - everything seemed fine! Although... there was one thing she saw on the x-ray - a little bruise on the rear spine (she was not sure). He had more painkillers and i gave him morphine through an arterial line. He got even worse. Two days later, we tried steroids and finally something worked! I was so glad too see my boy in no pain. He was on steroids for 2 weeks - 3 days after he stopped using them he beginned to have the same symptoms again - losing power and could not walk - whined when he got up/down the couch. So now he is on the second steroid dose - he has one week left. And i have a appointment with the vet after 2 days and i want her to just find out what is wrong with him. X-rays shows nothing :/ He´s is in so much pain when he is not on steroids. And these steroids are not good for him in long term use, i know what they can do to dogs. Could this be Spondylosis, Intervertebral Disc Disease, slipped disc, Wobble, some nerve disease ... or something else? Pleas can someone tell me anything about this.... Thank you!
