Is it safe to use a human lidocaine patch on my dog's leaking wound?

I would not apply neosporin as if licked it can cause digestive upset for Archie. I would however, still clean it up with the saline solution, and monitor the site for any swelling, open wounds, etc. You can also use a warm compress a few times a day to help reduce any swelling as needed. If the area remains red even after care, continues to swell, or is painful or oozing debris, then scheduling a recheck with your vet is best.

It is not a good idea to put hydrocortisone on a cut as it will HINDER healing and help bacteria infect the cut. Please wipe that off again. There is also no need for lidocaine (a local anesthetic). Unless the skin is cut all the way through (as I have described in your first question), you do not have to put anything on the cut, just let it scab over and heal by itself.

Ouch! In some cases where wounds are on areas that can't be closed by suturing or are constantly being agitated, keeping the wound covered to prevent increasing infection/debris from entering the wound may be needed. I've seen success with using manuka honey for treating large infected wounds and increasing healing, (usually with bandage changes every 12-24 hours) as well as using hydrocolloid bandages that protect the area by acting as a sort of skin barrier, allowing the wound to breathe but continue to heal/allow for new tissue growth underneath without allowing debris into it. There is also progress being made with using fish-skin bandages to create another fake skin barrier and allow healing underneath. If you're not currently, I'd recommend speaking with a veterinary dermatologist who can better instruct you in these procedures and monitor progress over time.

Oh no, poor Cat! You may need to be a shirt on him to keep the dog from licking at the wound. Cats will fit into baby shirts, and you can find a cheap from an op shop. Usually an infant size 3-6 months will fit a cat. You can clean the wound with warm water and antiseptic soap, but I don't recommend putting any ointments on it. Although quite safe on superficial wounds, cats groom and ingest most of the topical ointment you apply and therefore should be used only under direct veterinary supervision and if there are no other appropriate options. Many human ointments contain multiple other ingredients which are not necessarily safe to be swallowed. Keep an eye on the wound, and if it becomes red, swollen, warm to the touch, or has pus, it's infected and cat will need to see the vet for antibiotics.

First, consider seeking veterinary care since wounds can often be deeper than they appear and can get easily infected. 1. Clip the hair away from the wound using buzzing-type clippers, not scissors or a razor. This is so you can monitor the wound and keep the hair out of the way to help with healing and keeping it clean. 2. Disinfect the wound once with peroxide or a first aid chlorhexidine wound soap. Do not continue to use peroxide, or alcohol, as this will delay healing. 3. Apply an antibacterial ointment, such as Neosporin, twice daily. If needed to clean the wound, use a warm wet wash cloth to gently wipe away and dried fluid. 4. Prevent all licking or scratching of the wound by using an e-collar. Licking will delay healing and spread bacteria into the wound 5. See a vet if Leo experiences prolonged lethargy, decreased appetite, vomiting, diarrhea, or a rectal temperature over 102.5, or if there is creamy discharge or discharge with a foul odor, or there is swelling around the wound.

In these cases the most appropriate disinfection depends upon the location of the wound. Generally speaking disinfection may be started at home with very diluted hibiscrub or betadine or salted water baths. Buster collar may be useful as well to avoid any licking/scratching. Please give us more informations about the wound and possibly attach a pic on another question on the forum so we can give more specific advices.
