Kiya got this red bump on her nose for the last 2-3 weeks. It does not seem to be bothering her as she is not itching it, but it is red now and was once going down to neutral color, but now its back to red. We took her to the vet and the vet said that it kind of looks like a small tumor, but he did not want to do biopsy as it would leave a scar on her nose, and recommended to bring her back if it keeps growing. It does not seem to growing after a week, but it's not going away either.
We were feeding her for a about a month from a plastic food container as she was on a blended diet, then once we noticed the red bump we switched to metal bowl as we saw another resource online talking about a similar nose bump due to plastic dermatitis dogs can get on their nose from eating out of plastic bowls. She has been eating from a metal bowl for a week now and the bump does not seem to be getting smaller or growing. It is still red. Any ideas other than second vet opinion?
