Sorry I misunderstood the therapy you are interested in. I'll be really blunt about this as I feel you would be with me if the situation were reversed. Bacca's liver shunt needs either surgery or management with diet, antibiotics and lactulose to"flush" the ammonia from his intestines BEFORE it goes to his brain. As you know all too well, his clumsiness and walking into things is because of the toxic amounts of ammonia in his brain. The lactulose that I keep talking about should help keep the ammonia from becoming "toxic" and move it through out quickly in the feces. The antibiotic will help to keep the bacteria that cause the ammonia under control and the low protein diet you already know about. (Very simplified lay person breakdown of a complex condition) Dr. Shelli has mentioned that sometimes the damage from this is permanent and could be life ending. This can't wait, please start it now. She also mentioned that he should probably be admitted to the vet. hospital for treatment especially if you are already using this protocol. I really believe that you could give him some quality time if you act quickly. I know he may look ok but this is deceiving -his falling around and walking into things would not be improved by hydro therapy but by an inexpensive combination of diet, antibiotic, and lactulose. Please call your vet and please forgive me for being so blunt but it is because I care that I would even post at all...
