PLEASE HELP BOBO...Hi all, Bobo's mom here...since Thursday Bobo has been yelping on/off. I'm not sure what is wrong. I took him to the vet and the vet didn't have much to say. Didn't offer x-rays or anything, just prescribed an anti-inflammatory medication.
So now it's Tuesday and he's still yelping here and there. He's hiding under tables and chairs so I can't get to him I'm guessing. He seems very skittish and afraid of everything (normally, Bobo is not like this...he stops on walks just to stare at the big trucks passing by). He won't play, at all. Won't sleep next to me...has been sleeping on the floor-- he eats still and is going to the bathroom but other than that, all he does is sleep. He seems so miserable.I'm still new to the whole dog world (have had Bobo since March 2008) so any advice, insight, or anything else is much appreciated.To add to this, I've been really sick too so Bobo & I look like 2 messy peas in a pod! Ugh!

Not looking well this morning
Poor guy
Thanks in advance for all your help guys!
EDIT: Bobo is about 2 yrs old (not sure since he was adopted from a shelter) and he is still running during our walks. He turns around when he yelps as if to see what's hurting him. I don't think he's losing his ability to see or walk...at least not at this age. He did yelp when trying to sit down once so I'm guessing he hurt his lower back near his bottom? I've checked all his paws and don't see anything. :-/
