You are doing a good job - we know you love and care for your baby.
I think you should contact the University of Tenn - they are an excellent teaching vet school with high technology.
Here are some other things:
Maybe look into a Raw food diet. I say this, because a raw food diet produce very, very little waste (poop) - maybe 1 time a day (or 2) and very very small. (Nature's Variety is a good brand)
Also, maybe ask your Vet about getting him to write you an Rx for Lactulose. You can get this filled at Walmart or Costco (bigger bottle for cheap). Anyway, they give lactulose to dogs with liver issues. The reason why is, Lactulose binds to toxins (those meds he is taking and poop toxins) in the body and rids them thru elimination. And the waste produced from Lactulose is like soft ice cream - so that may be very helpful to your baby. And the lactulose is not harmful for him....
Please keep us posted and let us know if there is anything at all we can do to help you get to the bottom of this
