My young dog has a growth on his gum. Is it a canine papilloma?

I have noticed a papillomatous growth on my 11 month old dog's gum line, as pictured. My wife and I are physicians and believe it to likely be CPV, and plan to just observe it over the next week, but we were hoping for a vet opinion.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! I agree! The growth has the classic look and location for CPV. It is contagious and dogs get it from playing with other dogs at dog parks, doggie day care or from playing with their normal dog friends. The immune system does clear it eventually though it can take several months sometimes. I usually crush them with my fingers or a hemostat to speed up the process. There is limited evidence that a 10 day course of azithromycin also speeds up regression. He shouldn't play with other dogs until it is completely gone. I hope this helps and I wish Ollie the very best!
