Infection?

My dog got razor burn after being at the groomer, he then kept rubbing along the carpet and created carpet burn, I have been cleaning with diluted betadine & using wound gard spray and putting him in a diaper for as long as he will stay in them to stop him rubbing/licking it more.. does this need antibiotics or will it heal if I keep doing this?

Hello and thank you for this interesting question.  It is not always necessary to shave a dogs' testicles, especially if it gives rise to soreness.  Other causes of scrotal inflammation connected to rubbing may include fleas, mites or nicks in that area, or pain eg in the event of lumps or acute injury such as testicular torsion; be especially aware of the latter as it can be quickly fatal.  Furthermore, prostate disease and sometimes bladder infection can present in this way.  Assuming the cause to be as you described, even this must be extremely sore and soreness leads to further licking, creating a vicious cycle; pain killers might be necessary (one appropriate to that patient; please note that some common human pain killers can be fatal in other species).  Therefore, in balance, we feel that you do need to see a vet, perhaps relatively soon as this condition must involve some degree of distress. Antibiotics, however, may not be necessary.

Because some more severe conditions can present like this and because your dog does sound to be painful in a very sensitive area, please call your vet and ask to be triaged as to when an appointment is necessary.
