Okay, there's a few things that could be going on. This is a case where I would visit the vet, as potentially serious conditions could be to blame for this, and we don't want to overlook something like that. And something like an infection will only get worse the longer he goes without antibiotics.
Blood could be from a urinary tract or bladder infection. This typically comes with a few other symptoms as well, such as frequent urination, straining, painful urination, odd posture while standing, painful abdomen and other abnormalities along that line. Normal treatment is antibiotics.
Trauma to the penis or abdomen could also cause internal bleeding, which leads to bloody discharge, so that's a possibility if he had something traumatic like a fall or whatnot occur in the past few days.
Another possibility is something like prostate disease. This is not going to be a situation if he's neutered. But if he's intact, it's a possibility. It's more common in older dogs.
Here's a bit more on that:
Bladder stones also come to mind. Anything that seriously upsets the lining of the bladder can trigger bleeding. They can be dangerous too in that they can cause blockages in the urinary tract. So that's something you'll want to investigate as well. An exam can often detect these and there's other diagnostic methods that can lead to diagnosis as well. Some diseases, diets and medications make a pet more prone to this.

Tick-borne illnesses can also trigger blood in the urine. Does he spend a lot of time outside? Particularly in areas where there's tall grasses? That makes a dog more likely to get a tickborne illness, though even a normal walk in the park can lead to a tick bite as well.
I would be on the lookout for other signs of a tickborne illness like aches, poor appetite, fever, and general signs of illness.
And then there's the possibility of some type of tumor or growth. Some of benign, others malignant. And both can be seen in dogs of all ages. So if nothing else seems to be the case, this will likely be a route that will be investigated.
Also, here's a few things to monitor on your dog:
Temperature can be checked rectally with a bit of vaseline on the thermometer - this can give you an idea of general condition. It should be between 100.5-102.5. Anything below 100 or above 103 is a serious problem.
Checking the gums is an indicator of your dog's circulation. If there's internal bleeding, anemia, a disruption of normal blood flow, or serious illness, the gums will turn very pale, almost white in appearance. This means that the blood is not properly receiving oxygen or there's a loss of blood or red blood cells.
Normal gums will be bright pink to a pale pink. Abnormal gums are white with greyish, blue, or yellow.

I should note that I've seen perfectly healthy dogs with gums that are slightly paler than those pictured in the "normal gums" picture, but there's always a distinct pink tone.

The normal heart rate varies depending on the size and age of the dog. A puppy has a heart rate of about 180 beats per minute. And adult dog will have a rate between 60-160 beats per minute. Small toy breeds can have normal heart rates of 180 beats per minute. The rule is the younger the dog, the faster the heart rate (for puppies). And the smaller the dog, the faster the heart rate.
Normal pulse is between 60 and 120.
Also, you can check capillary refill time. If you apply firm pressure to the gums, the area should turn pale and then quickly return back to normal (you can try this on your own skin to see what I mean). If there's no difference, or if your dog's gums take a long time to return back to normal, there could be a problem. The gums should return to normal in no less than one second and no more than two 1/2 seconds.
I hope this gives you a bit more insight into your dog's illness! If you have any questions, just reply, okay?
I hope your dog is feeling better soon! Let me know how he does and don't hesitate to let me know if you have any additional questions!
