We rescued our guy Rocky at 4 months (5 months now) and we have gotten many questions if he is a CC. He is a little over 30lbs now but has some big paws! His face looks so lab/maybe part pit to me but also can see cane corso; just not sure if he is over 50%\ full CC.

He is also having tummy issues and had a prolapsed rectum coloplexy before we got him due to puppy diarrhea and is having it again. I know many are allergic or sensitive to chicken and he is on bil jac large breed puppy formula. He has been waking up throughout the night to poop and it smells foul and is straight liquid w/ mucus— maybe a parasite??

Any advice overall? Thank you!!
