Why is my dog's paw very swollen, red between toes, and limping?
Ouch! Chopper's paw looks quite inflamed and uncomfortable! Some of the more common causes of swelling between the toes are related to contact allergies, ingrown or infected hair follicles, or immune system disorders. Peroxide can be beneficial to clean out an open wound once, but can actually delay tissue healing if it is used repeatedly. In the future, I would avoid using peroxide. Due to this degree of swelling and discomfort, Chopper should be examined by his vet. I didn't see any pustules in the photos, but his vet will need to closely look for these during exam, as they can indicate the presence of infection. Chopper may also need oral or topical anti-inflammatory medications or anti-itch medications to allow his foot to heal. Repeated licking is only irritating his skin further and could lead to a skin infection (if it isn't already present). Try to put an e-collar (cone) on Chopper until you can take him to the vet to prevent further skin damage. I hope that he's on the mend soon!
