Dog has deep gash. What to put on it? Does she need stitches?

It doesn't appear deep. If there is no active bleeding, clean it up with a diluted Betadine or chlorhexidine (Hibiclens) solution. I see you have a triple antibiotic ointment. You can dab a bit on the area. Place an e-collar (cone) on her to prevent pawing or rubbing. Monitor for lethargy, fever, bleeding, swelling, discharge or loss of appetite. These are symptoms that should be addressed by your veterinarian.

Poor Faith! Depending on how recently this happened and how clean the wound is now, it's very possible that it would be a good idea to stitch this. At the very least, it's deep enough that it looks like it will need antibiotics to prevent infection. I would recommend taking Faith to the vet today to have this checked, if you can. He/she can trim the hair away from the area and flush out the wound, and will determine if it needs to be sutured or not based on how things look at that time. Your vet can also prescribe antibiotics and pain medication if needed.

That appears deep enough and long enough it will require stitches to heal quicker and antibiotics so it will not get infected since the source is unknown. It is best to have it evaluated this evening if possible, but if not, then keep Neosporin on it and discourage her from scratching it and visit a vet in the morning.

It's a bit difficult to tell from these pictures, but it does appear deep and wide enough that it will need stitches. It's best to take him to a vet soon, because the wound will heal better the sooner it is cleaned and stitched. For now, you can flush the wound using a syringe or other dispensing device with warm water for five minutes. This may not be easy, because dogs tend to hate water getting near their face. I recommend having someone help you with holding Wish to make sure the wound gets flushed well. Infection is the biggest concern with these wounds; so after flushing, it's best to apply an antibacterial cream to the wound. Your vet will be able to advise further treatment after evaluating it. I hope that helps and Wish gets better soon.

Ideally, if the wound is fresh or recent, it should be cleaned, flushed and sutured by your veterinarian. Place an e-collar (cone) on Annie to prevent licking. She may need antibiotics and pain management which you will need to obtain from your vet.

I would make sure she isn't licking it and not being too active. I would keep her confined to a crate or small bathroom and only take her out on a leash for short walks to go to the bathroom. You can put a cone collar on her to prevent the licking. From the picture, they do look a litte red but otherwise it looks good. You can put a little neosporin or bacitracin on the area as long as it doesn't attract her attention to it. If she is leaving it alone, then the ointment will likely make her lick it and that isn't ideal. I hope this helps. If you are still unsure by how it looks, I would have your vet take a peek at it when you are able.

That is a very large wound and it needs stitches. I strongly recommend you find a vet to see him as soon as you can. The longer you wait the more difficult it will be to close with stitches. In the meantime just keep the wound clean and dry. I would love to recommend a product for you to use but you did not provide your correct location so I'm afraid there is not much I can recommend at this time. If you would like to post again with your correct location we may be able to help you more.
