Hi guys,

A few week ago I noticed my dog (miniature dachshund - 8 years old) was licking his front paw but didn’t think much of it. Last night he was vigorously licking the same paw and upon inspection, I found he had a small raised but hard slightly brown sore (picture 1).   
He doesn’t react when I touch it and only seems to lick this paw after a short 5 minute walk outside.

Called the vet and booked an appointment for end of this week.

I went to work today and left him in his room, nothing to jump on/off, just his bed on the floor with a few comfy blankets he likes to dig into.  
But when I got home tonight, he’s been vigorously licking his back left paw and iv now noticed a fresh red, slightly white core soft sore (picture 2).

I can’t see anything in the room which would cause this and iv spoken to the vet and sent pictures but they’ve told me to book in a visit, which I won’t be able to get along to for another 2 days.

Would anyone know what the first sore could be? Even a wart or something similar, and what the second, more recent sore could be or even how it could have been caused? He still walks fine but tonight he’s had a very slightly limp to his back left paw where that recent sore has popped up.

Cheers guys.
