I recently took my dog to the vet to get his injured leg treated. The vet done a check up to see if he was healthy and all, then when the vet got to the testicles she said that my dog might have testicular cancer because one testicle is bigger then the other. I was told that if i dont want the cancer to spread to the rest of the body then it would be best to de-sex him. I dont want to de-sex my dog unless i know for sure that he does in fact have testicular cancer. So, just wandering if anyone can confirm that my dog has testicular cancer or if there are any other symptoms of testicular cancer that i should check my dog for. Any help is greatly appreciated, thanks in advance.
