My dog's staple came out after skin tag removal. Should I worry?

Thanks for using Petco Pet Education Center, formerly Petcoach! The area will still continue to heal without the staple. Monitor daily for redness, swelling, discharge, or heat. If you notice that, return to the vet for further evaluation. Kisses to Lucky!

Peroxide can hinder healing and there are enough staples out that I would be concerned the skin is going to reopen/tear from movement. I would try to get her into your vet or an ER vet ASAP to have a few extra staples/surgical glue put in to prevent the remainder from pulling apart. In the meantime, you can keep the area clean and debris-free with a clean washcloth and limit ALL activity (leashed walks outside to go potty, kennel rest, etc) to minimize pulling apart the skin as it heals.

I can't see your previous questions, but if a staple was pulled, either of your options is possible, however the swelling may have been caused by the movement due to irritation of the tissues as well as part of the healing process. If the staple is very badly torn, or the suture site is opening, having your vet look at it and repair it as needed is best. If your pup is very upset with having the cone on, many pet stores carry "donut" collars that are like little rings that go around, as well as soft-sided cones. These can be a lot easier for a pet to handle and prevents them from bumping into walls, etc while still preventing them from getting to sutures/staples.

Since the incision is not open, as long as your pet is feeling okay (no fever, lethargy, etc).. it is okay to wait until the morning. At that time, contact the surgeon and schedule a recheck as they will definitely want to see the incision. It does look like there is some infection starting and that will need to be treated with antibiotics. If you have an Elizabethan collar or "cone" to put on her until you get to the vet, that would be a great idea. The area is probably tender and itchy and she may want to lick it, which may cause more damage.

The incision is not yet healed and they likely cannot come out until at least day #10. I do however recommend to have Shiro examined by the veterinarian since they are looking red. Make sure Shiro wears the elizabethan collar at all times. I hope this helps and please feel free to post any additional questions.

I would get him in sooner than Friday to have that seen. The fluid can be drained with a needle so that the swelling can go down without compromising the suture line. I worry that if it continues to swell, the skin could slough and leave him with a large open wound. Call your vet tomorrow and find out if he can be seen.

You can keep staples in for as long as needed, as long as they are not causing any irritation / other problems. I would agree with the vet and keep those in a little while longer. I would not place another staple in that area though. The incision appears to be intact still based on the picture. However, if the picture does not show how open it is, then I would have the vet take a look at this and make that decision on whether or not another staple should be placed.
