My dog has an open wound. Should I use coconut oil or bitter apple?

No, I would not recommend doing that on ether a wound or a hotspot, it is not effective and will likely make things worse.

Thanks for using Petco Pet Education Center, formerly Petcoach! I am afraid that this is an open wound and will require further local therapy with debridement, cleaning, stitches, antibiotics and pain control medications. I recommend that you have Coco evaluated by a veterinarian as soon as possible for further assessment and treatment as these wounds are painful and can get infected easily. Good luck!

Moonlight is such a handsome dog!! From your pictures I suspect that Moonlight has what is known as a hotspot, or moist dermatitis. You need to take him to your regular vet to have the area looked at to be sure. Your vet will likely want to shave the fur from the area and clean it thoroughly. Some hotspots respond well to topical treatment, others require systemic medications such as antibiotics and steroids. These areas of dermatitis/infection can get larger very very quickly, and can be very irritating and painful. They often are associated with some type of allergy, so your vet may need to discuss allergy testing/treatment/food trials with you as well. I hope you are able to get Moonlighy feeling better very soon!

He needs to be taken to the vet as it looks infected, he will need a course of antibiotics, i don't think this will require stitching but a bandage with a local cream may also be needed to help it heal faster.

A picture of Vinnie's wound or more or of a description of its size and location would be helpful in giving you advice. If it is a small wound on the skin (less than a centimeter in size) you could try gently cleaning the area with hydrogen peroxide and applying a triple antibiotic ointment to help it heal. However, if Vinnie's wound is larger or not healing within a few days I'd recommend he see a veterinarian for evaluation. If the wound is large enough he may need antibiotics or even stitches to help it heal. Thanks for using Petco Pet Education Center, formerly Petcoach!

Wow, that looks quite deep, and Roxy needs to see a vet sooner rather than later. Gently clean the area with warm water and antiseptic soap. Keep it clean and dry, and prevent her from licking it with an Ecollar. Get her into a vet as soon as you can. Best of luck.

If your vet can't get Blueberry in sooner, you need to consider going to an emergency vet. I would not allow him to lick the area and it should not be covered. He likely need oral antibiotics and may need it surgically addressed.
