This is probably caused by an allergic reaction. first of all make sure you de-flea Zeus regularly every month with a high quality spot on (ex. Advantage) as fleas are by far the most common reason for these reactions. If the fleas are not the problem, it could be an allergic reaction to food or an environmental factor. this is more complicated to treat and will sometimes require medications such as Steroids, anti histamines or Apoquel in order to stop the allergy.

Hi and thanks for posting on Petco Pet Education Center, formerly Petcoach!

Bumps that appear suddenly under the skin sound a lot like hives which is an indication of an allergic reaction. There may be other causes as well such as a bacterial infection. I would recommend Ty see a veterinarian right away. If they are hives, Ty will need a steroid and antihistamine injection or other medications as necessary.

What causes red bumps, runny nose, and itchy face on my dog?

It could be that Zeeke is having an allergic reaction, and he's pawing at his face to try to scratch it. I would take him into a vet now for an exam. If he is having an allergic reaction, it could progress to breathing difficulties, and that becomes a medical emergency. The vet can determine if he is having an allergic reaction, and can treat with anti-histamines or steroids.

Why does my dog have bumps and scabs on his skin after playing?

With the description you provided it sounds like Zeus may have a skin infection. A skin infection can be caused by a few different things. Zeus may have allergies. I would recommend bringing him to your veterinarian to have them evaluate Zeus. He most likely will need antibiotics and potentially a shampoo. If your veterinarian suspects allergies they can discuss different medication options for him. Thank you for using Petco Pet Education Center, formerly Petcoach.
