This cant be it

My baby is sick.

He has been diagnosed with Cushings Disease for around 8 months now. His heaviest weight was around 120lbs 

Hes was huge and swollen. 

Hungry and thirsty all the time with no desire to get up and move at all.

His pills for Cushings regulated him out and he seemed to be taking to them well. He got back down to his normal weight at around 85lbs. 

All of a sudden, within the last month, he has dropped so much weight it looks like it is hard for him to even hold himself up. 

55lbs is his current weight...and that was taken 3 weeks ago. I'm sure its lower now.

We took him to the vet and had his medication dosage checked.

His test came back a little high so we lowered the dosage. He has a UTI so that is being taken care of as well (cushings disease causes a lot of uti's), but the weight is still not under control. He no longer eats dog food...or any food if it were up to him. 

I have tried everything.

The roasted chicken from the grocery store, hot dogs, chicken livers, macaroni and cheese, spaghetti, rice, hamburgers...he wants nothing to do with any of it. 

It has resulted to me force feeding him, which I am sure he is not getting the amount that he actually needs to gain any amount of weight. 

I am also squirting water into his mouth with a syringe because he has had no interest in water too.   

I am desperate. 

I am hoping that this is just a bump in the road.
I'm talking to the Dr. tomorrow.
