It'll take a while for the meds to do their work. There is nothing that we can determine is the cause. The outcome is a bacterial infection and the cause is from abrasion. The abrasion is the curious part. Its only on the left legs and at the 'elbow' joints. Only Bubba has this, his sisters are fine. These dogs are exceptionally clean and spend a lot of time grooming themselves. And they really enjoy their winter snow baths.. I just didn't want this to get worse and because these breakouts are on the joints and fairly swollen, the last thing I want is some permanent damaged. Bubba is very valuable to us as I'm sure many of you can relate.
