My dog has hard lumps under her healed bite wounds. Should I worry?

I can't really see the pink area you are referring to in your picture, but I agree that the laceration appears to be healed. I am wondering if the pink area is simply an area of new scar tissue. Occasionally there will be granulation tissue that inhibits full skin healing, but this is usually red tissue that bleeds. If the wound is not completely healed a surgical procedure may be necessary. She is probably due for vaccines at some point in the near future; you may want to have your veterinarian examine the area the next time she goes in for vaccine boosters.

I would recommend that you have Haider re-examined by the vet to determine what is going on. These could be bite wounds or could be decaying tissue due to an underlying infection. The vet may need to change up Haider's medications based on what they find.

Scar tissue can be a factor due to inflammation from healing if the injury deeper affected the muscles. You can apply ice to help with swelling until you can have your vet recheck the area to be sure. Some times further antibiotics and pain meds are needed, sometimes it is healed enough it just needs time

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Bo! I swelling below the wound can be from inflamed and thickened tissues, from the bandage being too tight, from fluid build up under the skin (seroma) or infection (abscess). Ideally Bo should be seen by your Vet. If you can't do that then warm compress the area twice daily and if it doesn't resolve in a few days have him seen. I wish Bo the best!

What you are describing sounds like scar tissue, but I would have to see it to be sure. Scars will not grow hair, but tend to get smaller and less visible with time. Puppies will heal better than adult dogs, so the scar should be much less obvious within a couple of months. Unfortunately, there is nothing you can do to encourage hair growth in this area if it is a scar. It's also possible that the lump is due to a deep infection. If the lump grows, appears red, or starts to ooze fluid, then it's best to take her to the vet for an exam. I hope that helps and all is well with your pup.

It's likely to be infected, i would recommend to take him back to your vet in order to get it checked, maybe he needs an antibiotic course and maybe the scab needs to be debrided, it really depends how bad it is.

It could be a localized reaction to the injections. If they are not bothering him I would just leave them alone for now. Just monitor them closely and if they continue to enlarge, burst open or start to bother him then you need to call your vet.
