What's wrong with my stray puppy's healing sore and hair loss?

i am sorry to hear about your dog! It is very difficult to evaluate the skin by a photograph but it appears there is a defect/wound in the skin here? I would be concerned that this was an abscess that ruptures, a wound that isn't healing and is infected, or we could have something like a cuterebra (a fly larvae that lives in a hole in the skin- look closely and see if you see a tiny creature moving inside the hole!). I would recommend a visit to your vet- the area may need to be flushed/cleaned and have antibiotics prescribed. In the meantime, I would put an e-collar on your dog or a t-shirt if it would be covered by this to prevent your dog from licking/aggravating the skin. You can also clean the area with a mild soap or Hibiclens (available at the drug store) and apply an antibiotic ointment like polysporin to the area until your vet can see him.

I am sorry to hear about Mickey! A photo of the area would help us better answer your question. Some sores can develop from things like a small wound or insect bite but others can be from bacterial or fungal infection or more. You can clean the area with mild soap or Hibiclens (available at most pet stores) and apply a topical antibiotic ointment. If your dog is licking at the area he may need an e-collar (the lampshade shaped collars) to stop this until it heals. If the area is worsening or not starting to improve within a few days a visit to the vet is recommended.

Hi. This appears to be a hot spot on him. This is basically an area of a moist dermatitis , or skin infection. They are usually secondary to allergies of some type. They are treated at the veterinarian by clipping the area, cleaning it with medicated cleaner, and then antibiotics and antiinflammtories. I'd call your veterinarian in the morning for an appointment

Thank you for submitting your question regarding the dog. Skin disease is frustrating as many conditions can appear similar. If the dog is very itchy, then I worry about fleas, mites or allergic skin disease causing the issue. If this is not the case, then a hormonal issue such as a thyroid or an adrenal gland disorder can cause the skin to look like your picture. Unfortunately, you will need to see a veterinarian to know for sure. Good luck!

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!

It could be caused by an infection, ringworm, flea allergy, or mites. She really should be examined by a vet to determine the cause and best way to treat. Your vet can do a skin scrape or culture to help diagnose and then prescribe medications to clear it up. She may need an antibiotic, anti-histamine, or corticosteroid to help treat.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor baby! It could be a burn from heating pad or lamp. Or it could be a hot spot from excessive moisture from the mother licking the puppy or lying in urine. Hot spots can crop up quite quickly. Since the puppy is so young it should ideally be seen by a Vet. the fur should be shaved to evaluate the area. If it is a hot spots can heal very quickly. I hope this helps and I wish you all the very best!
