Poor pup! If the wound isn't healing, it's likely that it is infected and will need prescription antibiotics to treat it effective. Because of this, I would recommend taking your dog to the vet tomorrow morning for an exam - he/she can take a look at the wound and determine what is needed to treat it. In the meantime, if you're able to gently clip the hair and matted discharge from over the wound, this should be fine to do. You can also gently clean the area with some warm water and antibacterial soap. I would not recommend using peroxide, as this may sting and often causes additional tissue damage and irritation which can make healing more difficult.

    If the wound appears to be healing, then you may not need to worry about it. However, without examining Marley, I can't tell you for sure if it is healing. You can take 3 pictures and attach them to a new Petco Pet Education Center, formerly Petcoach question and we may be able to help you more. For future reference, I routinely recommend the following steps to help a wound heal if you decide not to have it evaluated by a veterinarian: 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. 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 or dog booties or socks. 5. See a vet if your pet 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.

    Ouch! This looks like a fight wound or a wound from some other type of trauma. If he will let you I would try to clean with some mild soap and water. He is likely going To need some professional attention by a veterinarian. Your vet will be able to help shave the area, ensure none of the areas need stitches and prescribe some antibiotics and pain meds. I hope this helps.

    The wound may heal on its own, but since it is surrounded by hair, I would worry about it getting infected. And since we don't know what caused it, there is likely bacteria in the wound already. I would recommend having your veterinarian examine the wound and clean it. That will allow them to determine if it is likely to heal on its own or to determine if it need any additional treatment other than cleaning and possible antibiotics. Good luck! I hope that was helpful and answered your question. Thanks for using Petco Pet Education Center, formerly Petcoach.
