Prayers needed for our sweet pup

Starting Sunday afternoon, our sweet Abby began to show some signs of distress.  By Monday morning we decided to take her to the vet.  It turns out that Beagles are prone to disk issues.  We received an anti-inflammatory and some pain med, and were told to keep her down for two weeks.  Andrew explained that the situation could become serious, but the vet felt it had been caught early enough and she would be fine.  She clearly felt better yesterday morning, and attempted to scratch.  Something happened that caused her to yelp, and she disintegrated throughout the day.  Andrew took her in this morning, and honestly, it could be better.  It could be worse, but it could be better.  She was given a cortisone shot, and sent home with some prednisone.  They hadn't done this initially because of side effects, and she just wasn't as serious Monday.  If she isn't better by Friday, she is in serious trouble.  We would appreciate some prayers for our sweet girl.  She has been the best dog ever.  She doesn't jump on people and she doesn't lick people.  She doesn't bark, and she loves, and loves unconditionally.  She snuggles with us and is so good with our cats...even helping our fat cat clean himself.  We've had her less than two years and that just isn't long enough.  I know that there are far greater problems out there, but if anyone has a prayer or two to spare we would appreciate it!
