Poor Austin! He could have an infection there, he may have been injured, there could be a foreign body, or he could have allergies. Ultimately he will need to see a vet for it, as he sounds pretty uncomfortable, so I'd take him into the vet in the morning. Tonight, you can try an Epsom salt bath for his paw to see if that helps temporarily. I'd also put an Ecollar on him to keep him from licking it more. You can make one at home, and I will put a link below on how to do it. Best of luck. http://dogsaholic.com/care/homemade-dog-cone.html

    This could be due to an allergic reaction, even though infections are possible as well. It would be certainly ideal to have him checked as the allergy could spread and to treat appropriately as well in order to stop the itch completely. A buster collar will be useful as well to avoid any further licking.

    You should have Chico evaluated by a vet. Allergies commonly cause itchy feet, and some dogs will lick the itch so much they get a secondary infection that causes more itching and pain and the cycle progresses to the point you are at now. He likely needs anti-inflammatory and pain medications, as well as appropriate medications to treat the infection present and address the underlying allergy.

    This may be a symptom of allergies. The excess licking may cause a secondary bacterial or fungal (yeast) infection. Use an e-collar (cone) to prevent licking. Foot soaks in a diluted Betadine or chlorhexidine (Hibiclens) solution may resolve minor infection. Dry the paws thoroughly afterwards. You may need to have Sheru physically examined by your veterinarian to diagnose allergies. This can be frustrating though because allergies have multiple causes. Discuss allergy testing, hydrolyzed diets, food elimination trials and antihistamine use with the veterinarian.
