My dog's stitches are out. Is a smelly wound infected? How to ease pain?

This appears to be an infected wound. It looks like it has been caused by some sort of penetrating object. The antibiotics should start to kick in and sort the infection. You can clean the outside with warm water that has been boiled. If it is not improving go back to the vet in case there is a foreign body inside it.

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.

It looks like there is infection. Astro should be evaluated by a vet as soon as possible. He likely needs oral antibiotics since infection stalls the healing process. The vet will also clean the area to assess the health of the skin. Sometimes the stitches need to be removed and the wound can be healed "open," meaning that the stitches are not replaced and scar tissue fills in the defect. On a foot, this is often accomplished by bandaging with frequent bandage changes, and possibly topical medications, as well.

It’s difficult to say if this wound is infected based on a picture alone. I think it looks concerning but it would be a bit unusual for it to become infected so quickly. I think you can wait to recheck with your vet but if there is a different smell and the incision now seems open you should definitely see them today.

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. It is very hard to say if the wound is infected or not without examining your dog in full. In general, infected wounds are discharging, smelly, hot and painful to touch. Many dogs with infected wounds are generally unwell. A visit at your local vets is recommended to assess the wound and decide on the best treatment for Oreo. I suspect he may be prescribed an antibiotic cream or ointment to speed up healing.

The wound probably got infected, this is not uncommon but it needs to be treated. you will need to take Scruffy to your vet today in order to get it checked, yor vet will clean the wound and prescribe a course of antibiotics.

That looks like it's healing pretty well at this stage. Keep an eye on it for any redness, bleeding, seeping, swelling or her feeling sick or lethargic. Keep her confined, going outside only on a leash and only long enough to go potty for another week or so until she heals completely.
