I would take Riley to your vet sooner rather than later. A lump on the testicle is not normal, especially if it's grown in size in a short amount of time. Given that he is a young dog, it may not be cancerous, but there are other conditions that would necessitate him being neutered for the sake of his health.

    Riley needs to be seen by a vet ASAP. A tumor in the testicle is not a good sign. The tumor may be releasing hormones causing the prostate to enlarge which is in turn pushing on the urethra causing the incontinence. Neutering may be curative so get him to your vet ASAP for an exam! Hope this helps. Best wishes to you and Riley!
