Dog face sore bleeding after pulling off a scab, what should I do?

If it was just a scab and there is no active bleeding your pet should be fine. No worries. If it looks a bit irritated you can always put a thin layer of neosporin on it until it heals completely. A new scab should form soon if it was ripped too early.

It looks like what we call a hot spot or moist dermatitis. These looks really painful. I would have him seen. He will most likely need some antibiotics and some topical medication to help dry this up. They can also give you something for the itching or pain relief. These usually heal pretty quickly once they stop messing with them.

You can put an antibacterial cream on it 2-3 times a day for a few days and just monitor it, if it seems to be getting worse - take Ace to your vet in order to get it checked and treated as it may be a fungal or parasite related lesion as well.

Because it is localized to the one spot than you can alternate neosporin with cortisone cream to help keep it clean and take away some of the itching. It does not appear scarred so hair should regrow when it heals. If it doesn't improve in the next day or so your vet can prescribe oral medication to help with the itching and infection

Place an e-collar (cone) on him to prevent further licking or chewing. This may be enough to allow for healing. Keep the area clean and dry. If it doesn't heal or if it grows or spreads, have Barnaby physically examined by your veterinarian. He may need antibiotics or further diagnostics, such as a fine needle aspirate or biopsy, if it is a lump or mass.

Thanks for using Petco Pet Education Center, formerly Petcoach! This may be due to a focal infection or mild ulceration from a mild traumatic injury. I recommend that you continue to monitor Patriot for now. It looks like it is already healing nicely. If it continues to heal then there is no reason to have him evaluated by a veterinarian. If no improvement is noted in the next week or it worsens, have him evaluated by your veterinarian for further assessment. There is a good chance that he will be just fine. Good luck and have a good night!

If you can rest her and keep the area clean, then the neosporin is a good option to see if it will scab over or dry up. If it continues to bleed or gets larger then you have to make a visit to the vet.
