I just noticed this growth on my dog's paw recently... I had the vet take a look at it and after just a quick glance, he said it was a wart of some sort. He didn't biopsy it or anything.. Just quickly looked at it, said it was a wart, and then moved on to something else.. However, it doesn't look like any "wart" I've ever seen nor does it look like the pictures of warts I googled. It's about the size of a pea and has the same consistency as his paw pad (squishy but firm at the same time..not like jelly squish and not firm like a hard callous). It feels like a paw pad would feel underneath the rough surface. Also, it seems to be painful if I squeeze it even just a little based on his reaction of pulling his paw away & then licking it.
I'm really worried it might be something bad... Like malignant, bad.
