Hi, First of all I apologize for my bad English. Pet forums are not enough in my country I am an 8 month old Golden Retriever Owner. One week ago, a neutering surgery was performed. About 2 days later, I noticed a lump(?) while dressing. I asked the vet and he said he would come in 2 days because he was out of town. I went out to research on the internet because I was impatient. Could this be a hernia or cancer? I'm so sorry for my bad English. I am waiting for your help, thanks for answers.
