Thank you for submitting your question regarding Murphy. Allergies are common causes of skin disease this time of year. Humans inhale environmental allergens such as grasses, weeds, pollens and molds. This results in watery eyes and a runny nose. Dogs can experience this, but they walk through and lay in the grass. Therefore, red and possibly itchy skin tends to occur on the belly and paws. Dog can also develop red spots from insect bites. Rarely a bleeding disorder can occur. In this case, small area of bruising are seen on the dog. I recommend that he sees a veterinarian. He will be examined and detailed questions asked regarding his lifestyle and diet. Testing may be recommended. Based on these results treatment can be started if necessary. If he is acting ill or the spots look like bruising (your pictures are a but blurry), then he needs to see an emergency veterinarian today. I hope this information helps!
