Luckily no, this is a wart which is a benign skin growth. Many dogs get warts as they age and they are nothing to be overly concerned about unless they get very large or are in a location to be cut when dogs are getting groomed. If they enlarge then we recommend surgical removal. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for your dog.

    If your vet already examined this and determined it to be benign, then it is unlikely to be cancerous at this point, but that doesn't mean that it does not need to get surgically removed, especially if it is bothering him. One option is to have it removed and then sent to a pathologist for histopath so you can determine exactly what it is for sure.

    According to the pic, It looks like a possible skin tag (fibropapilloma) which harmless, some skin tags can grow a few centimeters but that's need to be confirmed by a vet on examination . that's especially important with any mass that is growing in size, appearance, or color. In addition if it is confirmed as a growing skin tag your vet may consider removal. The bottom line it will need to be checked by a vet.

    Warts are usually non cancerous and do not need to be touched or removed, unless they are bothering Fiffy, but in order to be sure it's indeed a wart and not something else, i would recommend to have it checked by your vet.
