When you arrive at the veterinarian’s office, be sure to tell your vet about any and all symptoms. They will want to know when you first noticed the skin abnormalities, if your dog has been displaying any of the typical signs of a skin issue, if you have tried to treat it with anything over the counter, if you have fed him anything new lately, if he has had any changes in his routine or home that could cause stress, if he recently injured himself, or anything else that may be helpful to know about his situation.
As part of their diagnostic process, your veterinarian will need to rule out other possible causes that may be causing the skin issue. While the location of the skin issue will give the veterinarian much needed information about your companion’s condition, they will want to rule out possible causes that may be associated, as well.
Your veterinarian will then continue by performing a full physical exam on your dog. While it may be obvious where the lesion is and the signs it is causing your dog, they may want to do a full evaluation of your dog's entire body system to check for other areas of sensitivity that have not yet developed into a skin infection but are susceptible to it. They may also check for evidence of parasites during the exam to see if they are a contributing factor. As well as this, they'll want to assess for underlying health issues (such as endocrine disorders) which make infections more likely.
Your veterinarian may want to clean the affected area of skin to allow them a better look at the lesion. Clipping the area will remove excess fur from the region which will improve ventilation and allow for easier cleaning.
In addition to diagnosing and treating the skin disease and possible infection, you will also need to investigate the cause of the initial signs. During her examination, if your vet found evidence of fleas or other
ectoparasites, this would be treated. If it is in a location where there is a skin fold, she may take a skin swab sample to verify what type of bacteria or yeast is colonizing in the area. Further diagnostics may be recommended depending on the suspected cause of your dog’s condition.
