My pug dog who is 5 years old, male, started peeing blood, but then it went away. Last night, he left his bed and when I woke up this a.m. it was like a blood bath down stairs. There were probably 10 -12 pee sites, and all had brown or red (blood) in them. Is this a bladder infection?

Take your dog to a vet FAST! If this were your mother, wouldn't you call an ambulance??

Yep, get him to a vet asap!

If it is a bladder infection it sounds like it's moved to the kidneys which would be very painful.

Take the dog to the vet ASAP. The blood in his urine could be a symptom of bladder stones, kidney stones, or a bacterial infection.

I am just going to echo everyone here, VET NOW!
