My dog keeps licking a wound between his toes. Is it a foxtail?

That red bump in between the toes is suspicious for a grassawn/foxtail. I suggest you have her examined by your vet (not an emergency). In the meantime, you can try soaking the foot in warm Epsom salt water (10 minutes 3 times per day) to hopefully draw out any foxtail that may be under the skin.

This is not a recurring injury. This looks like foxtail/grassawn lesion. There is likely a piece of grass up there that is causing a chronic infection. You need to get him to a vet for an exam and treatment. ( https://www.google.com/search?q=foxtail+dog+foot&oq=foxtail+dog+foot&aqs=chrome..69i57j0l4.5209j0j7&sourceid=chrome&ie=UTF-8 )

Yes, I would get a cone. Be sure that the cone extends past the end of his nose or he will still be able to lick. This could be a serious problem. Bumps between the toes can be anything from a cyst, to a tumor to an abscess. You can keep soaking it with Epsom salts. You can apply the aloe but it's not likely to help; Neosporin would be better. I suggest you don't wrap it. If you bandage it too tight or incorrectly then you can cause more damage. If after 4-5 days he is not better you need to get him to the vet for an exam.

These type of injuries are often due to a puncture between the toes. Sometimes the thing that punctures the toes stays under the skin. This commonly happens with thorns and grass awns. In both cases, an infection develops under the skin and will not heal until the source of infection is removed. Lioh's injury does appear to be infected from what I can see in the photos and it will be best to take him to the vet for treatment. For now, you can try doing a twice daily foot bath with Epsom salts to help decrease the swelling and help treat the infection. Just make sure that he doesn't drink the Epsom salt water, or it will make him sick. I hope that helps and Lioh gets better soon.

Yes usually there is an entry wound with something stuck in the paw. The picture looks like she has an infection between the toes. This is infected interdigital cysts. It can affect one paw or all four. Often they have some drainage and swelling. I recommend taking Willow to the veterinarian for an exam. They will look for a foreign body in the paw and if it's a paw infection they will prescribe antibiotics. You can soak the paw in warm epsoms salt solution for five to ten minutes. This will draw out the infection and increase the blood supply to speed healing. If Willow is licking this excessively please use a restraint collar so she can't lick the paw. These generally heal quickly with treatment. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Willow.

It's more likely to be either an allergy or a foreign body, if a foreign body (usually a grass seed) is suspected it will need to be removed surgically, if an allergy is suspected she will need allergy meds.

This is called pododermatitis. There are interdigital cysts between the toes that can get infected. I recommend soaking the feet in a warm epsoms salt twice daily to draw out the infection. Also use a cone to prevent Opie from licking his feet. If the sores are not drying up and healing then he should get a veterinary exam and mostly likely they will prescribe a course of antibiotics. Feet can take several weeks to fully heal. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Opie.
