Q. My 7 year old male neutered jack Russell is restless, keeps pacing, breathing hard (panting ) and has vomited twice . He just had a bowel movement.
A. It sounds like he is painful for some reason, either an injury, ingesting something he shouldn't have, which has resulted in some adverse reaction or a gastrointestinal obstruction, he could be having an allergic reaction, there are a number of possibilities. I recommend getting him seen by your vet as soon as possible for an exam, labwork and possibly x-rays to determine the cause for his discomfort and get him started on treatment.
