My dog has a dark red patch on each side of its belly—looks like internal bleeding but acts normal
Expert Answer
If dark red patches appear on a dog’s belly, it may be one of the following. 1. Skin inflammation: the patch may be caused by skin inflammation from allergy, infection, over-scratching, or other skin issues; if there are no skin-disease symptoms, try a gentle skin-care product or local anti-inflammatory.
2. Skin bruising or vessel dilation: the patch may result from trauma or bumping causing tissue bruising and vessel dilation, due to poor local circulation or vessel rupture; if the dog’s spirits are normal with no other symptoms, it may be temporary dilation—observe for a while, and if it does not worsen, usually no special treatment is needed.
3. Other health issues: the dark red patch could also be other skin problems such as hematoma or tumor rupture; if the dog later shows abnormal symptoms, further examination and diagnosis are needed to find the cause and apply proper treatment.
