My dog is licking her painful, crusty chest rash. What to do?

Updated On September 23rd, 2025

Pet's info: Dog | Maltese | Female | unspayed | 4 years and 1 month old | 4 lbs

Hi there! I'm really worried about my precious Bella. I've noticed that she's been licking her chest often and doesn't let me touch her chest which she didn't do earlier and it also seems that a gentle touch is hurting her and she jumps when touched. She does not have a bulge there but it hurts. Otherwise her behaviour is normal. I'm hoping that it's nothing serious. She just has skin rash just on her chest that looks like a red spot that changes into something crusty. What should I do?

Hi, I'm Dr. Johnson. Thanks for using Petco Pet Education Center, formerly Petcoach! Poor Bella! Based on your description I'm thinking Bella may have a hot spot (superficial skin infection) or either a yeast or bacterial skin infection. It likely would be uncomfortable when touched. Maybe posting a picture may make it more clear. But I think seeing your Veterinarian. If it is a hot spot or skin infection then they would like prescribe antibiotics, topical and maybe steroids. I wish you and Bella and the best!

    Thank you. Much better photo's. : ) This looks bacterial in nature, due to the lack of hair loss in these areas and the yellow crusting and redness of the skin. Some pets get random skin infections due to a challenge to their immune system, and I suspect this may be the case here. A short course of antibiotics should be tried first before suspected a true skin allergy here, unless of course she is also itchy all over and licking her paws. A topical spray antibiotic can also be used (hot spot sprays over the counter can help), but an oral antibiotic should be used here. If she has a resistant bug that isn't responding to the first antibiotic your vet chooses, you should consider getting her skin cultured to find out what antibiotic will work for this. Best of luck with your pet Bella moving forward and I hope that her skin resolves soon. Take care!

    Poor little Bella! It looks like she could have a rash, and it could be caused by allergies or a skin infection. I definitely think she should see the vet tomorrow. Try giving her an oatmeal bath tonight to see if that helps her, and put an Ecollar on her to keep her from licking it. I will put a link below on how to make one at home. I hope this helps! http://dogsaholic.com/care/homemade-dog-cone.html

    Oh dear, poor Bella! These skin lesions could be a sign of a bacterial skin infection (most commonly from underlying allergies and still possible even though pus is not seen), viral papillomas, benign or malignant masses, among other issues. Until you can get to the vet, keep an e-collar (cone) on Bella unless you are directly watching her because licking and scratching will only exacerbate these lesions. You can also try bathing her in a medicated shampoo (here is one example: http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=27980 ) to try to decrease her itching. Since she also has lesions on her lips, be sure that she is eating out of stainless steel bowls rather than plastic or ceramic since it is less porous and less likely to harbor bacteria that could contribute to acne around the lips. Also be sure that she is receiving a high quality flea preventative, such as Nexgard, Bravecto, or K9 Advantix II regularly to assure that a flea issue is not contributing to these lesions. I hope this helps and that Bella feels better soon!
