Last night my 3 year old female lab was normal as can be, then we noticed her hind leg had no feeling, and 20 minutes later the other leg went too. I took her to the vet and he's got her on steroids and an anti-inflammatory. He called this morning and the fever is gone but the paralysis remains. He thinks it's either a tick born illness such as lyme disease, which is treatable, or a spinal injury which would likely lead to me having to put her down. We're hoping for the tick born illness since the back injury likely wouldn't cause a fever. Anyway, I was wondering if any of you have run into this before. I know some of you have had a lot of dogs through the years. Hopefully someone can share a positive outcome from their own experience. Thanks.
