Good grief! That is expensive!!

Poor Brodie, I'm sorry that he is still having problems. I hope the vet will be able to find something (and it not have to end with surgery).

Did the vet ever have you try Pepcid? Just curious since I know T&P's Mom used to give that to Tubby and I've read where other people here have used it. If it's not a blockage and it's an upset stomach maybe it would help. Don't know if it would do any good if it's really food allergies. Worth asking your vet though.
