Over the last two days I have noticed Gillie has a lump by his willie. It is about 1cm in diameter, soft, doesn't hurt when I feel it and it seems to be loose beneath the skin. If it were on me I'd be tempted to give it a jolly good squeeze as it feels like a large spot or a boil but obviously being where it is I don't think he would appreciate it! How long would you leave a lump like this before getting a vet to look at it? I don't want to be a paranoid owner but then I don't want to ignore something I should be getting treated.
