I'm so so sorry to hear that... :(
Thankfully OP is in good health. I had a couple scares when he would eat a whole loaf of bread or a whole bag of chocolates but in the end he digested everything just fine. My mom would put liquids in his dry food and just feed him about anything, but he never had any problems other than some diarrhea here and there. I know I'm very lucky because many other Danes wouldn't be able to tolerate everything he ate just as well.
