Why does my dog have open wounds on her body with no obvious injury?

I would recommend that Chance have these wounds checked out by a veterinarian. They could be caused by hotspots, allergies, bacterial skin infections, fleas, mites, among a few others. Since they are spread out over the body, Chance would probably benefit from oral prescription antibiotics and anti-inflammatories, in addition to treating the originating cause.

Oh goodness. Those wounds look angry. I would highly encourage you to have her seen by a veterinarian. Bacterial or fungal infection is possible, but also immune mediated issues are possible as well. Best of luck and thank you for using Pet Coach.

A non-healing wound is often cancer. There are other possibilities: it could be a resistant bacterial infection. a foreign object in the skin (like a small piece of wood, grass or a bone fragment) that is causing it not to heal, it could be an auto-immune disease, etc. He needs to see a vet for an exam and some testing. There is no way we can give you a definitive diagnosis over the internet. The wound needs to be cultured an biopsied.

This could be more than one thing- ringworm, fungal infection, parasites, bacterial infection, allergies- if the wound does not seem to get better in the next couple weeks you should take her to the vet in order to get it checked and treated.

That's pretty severe for a pressure sore, and it looks like Stella sleeps on a comfortable bed. Pressure sores usually occur from a dog lying on a hard service. In addition, they don't show up like this all of a sudden, they get worse slowly over time. I'm concerned this could be from an injury. You need to have her seen by a vet in the morning to have this diagnosed and treated.

If it is the black dog with white legs with a large red lesion on his right rear leg, it looks like he has had a serious injury (not disease) where he either had a large laceration/cut and the skin edges are widely separated now or he had a large section of skin ripped away as can happen if he was perhaps hit by a car or had some other traumatic event. Under ideal circumstances, he would be sedated for the wound to be cleaned and flushed out and given an injection of a long acting antibiotic, pain meds and the lesion/leg would be bandaged for it to heal by second intention unless up close it looks like the skin edges can be debrided and sutured back together. I don’t see red skin all over though, if you have pictures showing the red skin better in other areas of the body other than the right rear leg that would help! Thank you!

Hello, it looks from the picture like an area of hair loss and inflammation of the skin, but not an actual open wound. I would be concerned that she either got a hot spot, or something spilled on her, or potentially being road rash. It could also be infection either with parasites, bacteria, or ringworm. I would have Masa evaluated by your veterinarian if it is not getting any better in a few days or if she is scratching a lot or if the area of hair loss is getting bigger. In the mean time, you can clean it with soap and warm water then make sure to dry it thoroughly. If She is scratching at the area, you can place a shirt over her to protect the area. Best of luck and hope this helps!
