Oh my goodness! You need to get him to the Vet!
Please, don't let him suffer any longer....Get him some help!! He is depending on YOU!!!! Call your Vet and make an appointment!!!
I absolutely agree with Janis. There is nothing much we can do, but maybe a lot a vet could do. I hope he will be okay.
I don't know how long this has been going on BUT I
can tell you without doubt..IF...
as you say ".He also has a smelly greenish-
yellow liquid coming from his private area. He has
problems pooping, and what does come out is
runny and dark. What should I do?"
Greenish-yellow liquid sound like a possible
serious infection-runny,dark poo could be
old blood...LEAVE THIS SITE AND TAKE
HIM TO YOUR VET RIGHT NOW!!!
Please come back and let us know how
he is doing?
