I am a newbie. Had my 5 year old rescue 9 months now. First year is real hard was he suffered an impaction. He is presently force fed critical care omnivore and yes he saw the vet 4 times. He is on antibiotics cause the vet said his bowels might be enflamed"enteritis". Since the first day he was on antibiotics he is sportin a black beard 24/7 am I doing something wrong? I should also note his face just started to shed. I know force feeding is stressfull but We have been force feeding him for a while now cause of his impaction. Just concerned about his black beard.
