I have a 7 year old miniature dachshund and he started acting wierd this morning out of nowhere. He's had a bulged disk before but it was 2 years ago and before I noticed he was acting off, I picked him up and he didn't yelp or whine or anything. He's being very sluggish but he's eating and drinking normally. He did INHALE his food this morning but his stomach isn't distended. I realize the logical answer would be a back problem but he isn't acting like he's in pain.
