I would question chronic pancreatitis. The sludge in the gallbladder could also be a factor.
What sort of symptoms again is it that your boy has?
Lethargic, doesn't get excited, play or wag his tail. Panting at times. Just lays around.
He is hypo thyroid, allergies, pancreatic attack nov, sludge in gall bladder. His vet isn't concerned about the sludge but his allergist is? No mucacele in gall bladder. He is overweight from cortisone for his allergies (working on that) he is a rescue so he didn't come with much info at age 2.5 now he is 5 yrs. we've come a long way but for me not far enuf!
