I understand this thing is best presented to a veterinarian but as usual my dog (chocolate labrador, 6 years old) develops issues when it's weekend over here and his veterinarian isn't available.
I noticed yesterday during a walk (but perhaps it's already going on for several days) that my dog paces a bit strangely and at one point he lifted his front left leg as if something got stuck in his paw. I checked it out but instead of some thorn or other sharp bits what I saw is this growth extending the edge of one of his paw pads:
As you can see, its surface kind of resembles the surface of the normal part. Also, I can't really see how overgrown has the part deeper around the pad gotten (that is, whether it's mostly dry "skin" on the surface or rather swelling that continues throughout the entire mass of the finger).
Also of interest is the fact that just a few weeks ago on the same leg but on the uppermost pad (the "heel") my dog had a growth that looked a bit different, more like a reddish swelling that produced discharges. It's mostly gone now and the vet back when he looked at it said it's just some sort of inflammation and gave my dog a topical medicine.
Does this look like a known condition and is it likely just a benign manifestation of some trauma from walking outside?
Thank you in advance.
EDIT: Here is a newer photo after wiping his paw. The normal area remains dark but the growth shows pink mass underneath the darker crust that slightly scraped off.
