Hi Zina,
It's best you take him to the vet to be thoroughly checked out. It could be a prostate infection, or some other inflammation/infection going on which needs treatment right away
i am concern i have a year old half chuahua half terrer who was ejaculated and had blood in his semen what do i do please help
Oh the poor dog! He's got to really be hurting. Please post back and let us know what the vet has to say. I hope it's an infection that can be easily treated. :-)
Sounds like a prostate infection. Let his vet know, as you are obviously going to do. Antibiotics should help. He might need to be neutered, though.
