Old English Beagle

Why my dog has developed a toe further?
My 2 year old dog and a half (half beagle, half Bulldog English) has, over the last 2 months, grew additional "toe" on its front paws. at the base, it is pink and fleshy, but you get to the point, it is more polish, as, and is rough not smooth. It seems to be bothering him, and I intend to take the vet, but nobody knows what it is? Or how does it work? It's really weird. I've had since he was 6 weeks and was in great health otherwise … Thank you!
I do not know what it is, but its probably not a question toes if it was u did noticed. The only way an animal can have an extra toe if she was born with it or if it has a kind of bacteria or disease. My kitten is born with 8 toes on the front and 12 rear. (Unfortunately he died two months later due to)
