Poor Ceaser! Rashes on the belly and along the genitals can be due to a number of reasons, including allergies to food or environment, yeast infections, fungal infections or bacterial infections. Fleas and ticks can also cause itching and irritation, thought it is usually not concentrated to just one area. Having your vet take a look is best, and your vet can provide treatment such as a daily allergy medication or other medications to resolve the issue. It is best to make sure Ceaser doesn't lick or chew at the area until you can get to the vet, which can make things worse by getting bacteria into and under the skin. An Elizabethan (cone) collar or old T-shirt can be used.
