My dog Buster is a Lab Terria mix. I took him to the beach one day. When we came home I gave him some pinnapple,strawberries and cantalope. He loves fruit,the next day he got bumps the size of quarters on his face,then on his ear and hind legs and toes.They started out as raise skin, then they dried up. The top layer of skin and fur came off. He now has raw skin ozzing water. I took him to a Vet., he said its not ring warm. He put him on antibiotic for seven days but still no change. I took him back to the Vet.but he is not sure what it is. He took a sample to send out to a lab and put him on a different antibiotic. PLEASE HELP!!!
