Paw licking

[SWHouston]

Jessica covered it all, but, I'm inclined to think it's a foreign object/sticker.
Some of our guys grow an abundance of Hair in the "palm" of their Paws. Not sure about the term, but the depressed area between their Toes and Heel. I've found numerous objects pushed up into that area (stick/rock/stickers) where I had to trim the excessive Hair out to find it.

Try a closer inspection and or trim in that area.

Allergies do indeed cause dogs to lick their feet, but *typically* they'll lick more than one... usually both front paws or all four paws. When a dog is only licking one paw it is usually indicative of an isolated incident, such as foreign body or injury.

How is she?
