I have a dog getting trained currently and was contacted by the trainer for an update yesterday. She let me know training is on tract but advised me that the pup has what she believes is an interdigital cysts. I gave her approval to take the dog to the vet for me and get it looked at and for possible treatment. My question is has anyone felt with this problem before? What was the corse of action that was taken for the problem. I attached a pic of the "possible" cysts.
