umm yes, dogs can too get hemmoriods though it's extrememly rare...it's usually something else.  For those that say they can't, research it on the web.  You need to take your dog to the Vet.  IF it is a hemmoriod, they can sometimes just tell you to use the same cream that you would use on yourself.  Hemmoriods in dogs are NOT life threatening (I've seen some people say they are and they are incorrect), though if left untreated for a long period of time it can lead to cancer.
