Aww poor Bogey. so sorry youre going through this worry. I hope everything turns out okay, and it's itching serious, hope he's back home soon, and feeling better. Sending you and Bogey big hugs, lots of love, and prayers. Please keep us posted on how he's doing, and I hope to read he's back at home. Will check in later to see he's doing.
Sounds like an obstruction, I hope you have a good bully vet. They need to x-ray him, even though some things will not show up on a x-ray, but they might be able to see a shadow. Sending prayers his way and hoping for the best.
