Help! Has anyone ever seen their boy have blood like this come from their penis? I don't think it's in his urine as that is clear as a bell....and he had urine testing done last month that came up great. Is he either biting at himself/biting his penis once unsheathed, has hair ring, a UTI, passing a stone or worse? I'm unsure since I never catch him during the act. He has been hormonal the last week....he gets that way roughly four times per year. Little to no eating or drinking, marathon running, shedding, and new fur growth. But in 4 years he's never done this quite as bad. this started this past January...did it twice, was medicated for uti, and it stopped. But now this has happened 4 times in 2 days. Thanks!
