Recently, I had a client who brought his dog in for skin problem. Bleeding was noted on the belly one day ago. Otherwise, there were no other complaints.
On closer examination, it was more severe than a superficial skin issue. The patient had a blood clotting disorder, leading to the ease of skin bruising and bleeding. Compared to the regular skin disease, this problem is uncommon.
I would like to advise pet owners to bring their pets to the vet as soon as possible, if lesions like those seen in the picture were observed. Look out for skin bruising or bleeding and petechiation on the gums if the skin problem that your pet is exhibiting is similar to the one in the picture.
