Poor Freckle! Without seeing a photo or completing a physical exam, it’s hard to know why this is happening. Pets can get red marks on the skin due to flea bites, environmental allergy, food allergy, contact allergy or hyperthyroidism. Red marks could also indicate bruising which is much more serious and significant. Bruising indicates platelet abnormalities and this can be fatal without treatment. Since you are noticing the issue is so widespread, I recommend to have him examined by his veterinarian today ideally. It’s always best to play it safe. Best of luck and please feel free to post any additional questions.
