I have a 6 & 1/2 month old Golden Doodle. He humps a pillow or his dog bed occasionally. My vet assured me its not sexual & he seemed to do it when he was bored. So today he started humping a pillow & I noticed he would stop to lick himself so I looked at him and he had a full erection (hot dog sized) sticking out & I couldnt believe it. Also it was dripping clear liquid. It went back in whithin a couple min. Naturally I googled it because I have never had a male dog but had heard this may happen. He never marks his territory& never lifts his leg to pee so I was not expecting this so soon. I read that he may need more exercise. After his pillow session he slept & I took him for a half mile walk in the cold nite air. He walks a half mile in the morning regularly but at night its usually a short walk. Any advice here?? Im booking him into the vet to b fixed but not for a month. Is this a constant thing that will happen?? If i walk him a mile to a mile and a half split between day & night should this help?? Thanks for your help.
