My puppy has a puss-filled bump on its tummy. What should I do?
Hi there! I'm so sorry to read about Choco's troubles. It looks like he has a pustule. This is basically a pimple-like lesion caused very often by a staph infection. Sometimes the lesions are singular, or sometimes they can spread and get worse.
If I have dog come in to see me with pustules, I will often prescribe a medicated shampoo to help clean the skin and also moisturize it. Dry skin can cause a break in the skin barrier and allow bacteria to congregate. I also will often times prescribe a course of oral antibiotics, to insure that the infection doesn't spread, and goes away quickly.
I would monitor the lesion, and make an appointment to see Choco's veterinarian. They can evaluate Choco's skin and make sure there is nothing else going on, and see if the infection is severe enough for topical and oral medications.
I hope you find this answer helpful! Best of luck!
