@LarryZek It sounds like it could be obstruction. Get him to a vet with an x-ray /ultrasound machine ASAP!
You're in Brooklyn. If you're around Bayridge or Bensonhurst I'd take him to Richmond Valley Animal Hospital on Arthur Kill Rd. in Staten Island. They're
great with bulldogs and understand all their "unique" issues. I've seen Dr. Christopher Powell there and he's pretty good.
Another option is the AMC (Animal Medical Center) on E 62nd st. in the city off of York Ave. We just had Blue there yesterday for an obstruction and they got the squeaker out via an endoscopy.
This is something you need to take very seriously as the symptoms you're describing point to an obstruction.
