My TJ has IBD. He was really bad when he was a baby, and after tons and tons of stuff, Tylan Powder is what finally helped him. He is almost 5 y/o now and he was like 99% good until June when he "caught a bug" and he had squirting poops with mucus for 2 weeks. The Metro helped him that time (didn't when he was a pup). But now since June, I can't get him to have steady good poops. It would be good for a few days and then he would have HUGE poops encased in a thick mucus like condom (sorry, that is exactly what it looked like). Anyway, I am adding a little pumpkin to his morning and evening meals, and it seems to help, but I resolved that if the mucus come back, he'll have to go back to the Tylan....
I hope you can get some relief soon for little Lola...
P.S. When Roxy turned 3 she developed allergies too
