Oh the poor pup! *sending healing vibes to Pixley (LOVE the name)* My boy had a partial blockage that was caused by rawhide (needless to say, he does not get rawhides any more!). He's fine now. As soon as he "went out" so-to-speak and passed part of the blockage, he made huge strides in recovery. But he scared me! Its very common and can be caused by almost anything - stuffing from animals, rawhides, even socks... Hope Pixley's feeling better soon!
