Get some cheap (very cheap... we are frugal here.. LOL) House Brand
Neosporin from Fred's or your dollar store and applty it to the
affected area. Sounds like what the vet calls "hot spots" to me.
The tiny.... very tiny tube of name brand Panalog (Pan-uh-log) that
the vet will try and sell you will set you back about $15 PLUS OV
(office visit).
