My dog has black spots on her belly. Are they allergies or infection?

My dog has black spots on her belly that seem to start getting better then get worse again. Could this just be allergies or flea dust or more like a yeast infection? It doesn’t really seem to bother her.

This looks like a mild bacterial skin infection. Dogs can get this from laying on damp ground. Often it will go away on its own. You can bathe the area with antibacterial shampoo once or twice weekly to help it heal more quickly. Since she’s not bothered by it I’m not overly concerned. Should it worsen please take her in for an exam. She may need oral antibiotics if is gets bad. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Marley.

Ouch! It's hard to tell how much is irritation and how much is the spot, but it's good that you have the vet visit scheduled already. Until then, I would just keep an eye on the spot and monitor for any changes such as size or shape differences, if it's oozing debris, hot to the touch, painful, etc. I would also keep the area as clean and dry as possible. Finally, it is best to place an Elizabethan (cone) collar on Coco or shirt over the area so that she can't lick and scratch at it. This will help reduce irritation and itchiness and can help prevent secondary infections from taking hold.

You could bathe him with a medicated dog shampoo and see if the spot is just a scab that will come off. If it is attached then you should just leave it alone and have your vet examine him to determine if treatment is needed.

Skin pigmentation can indicate irritation. You can try washing the area daily with soap and rinsing well. You can also add an omega 3 fatty for dogs to Ella’s diet and this may help after a few weeks. If it gets worse, have Ella seen by her veterinarian. I hope this is helpful and please feel free to post any additional questions.
