What's this spot on my dog's belly? Bite, tick, or ringworm?

This lesion could indicate a local bacteria infection, possibly ringworm, an insect bite, or just an area of rotation of unknown cause. You could continue to monitor if you feel comfortable and if it does not go away within a few days I would reconsider seeing your veterinarian to ensure it's nothing contagious like ringworm. However if it starts to grow, bleed, become raised, or seems painful it should be seen sooner. In the meantime you could consider cleaning it with a very mild soap and warm water and keeping it clean and dry during the day. As there is a possibility it could be ringworm wash your hands thoroughly after handling the site.

The most common reason that we see red circular rashes in dogs are actually bacterial skin infection. Tick bites rarely cause red circular rashes in dogs (it's more common in people). Ringworm certainly can cause a circular rash, but they often aren't red in dogs. I would recommend having your vet examine Chance and determine what they think is going on. They may be able to tell by looking at it, or they may need to do some special skin tests like skin scrapings or skin cytology in order to determine the best treatment for Chance. I hope that was helpful. Thanks for using Petco Pet Education Center, formerly Petcoach.

It looks like she has a pyoderma which is a skin infection. She should be examined and treated by your vet as she may need an antibiotic to treat the condition. In the meantime, you could bathe her with a medicated shampoo, like Douxo Chlorhexidine shampoo.

Skin lesions like Coco has can be caused by bacterial, parasitic or fungal infection, dietary or environmental allergies or sensitivities, immune system disorders, an insect bite like you mentioned, or a combination of the above. I recommend making an appointment to have Coco seen by your veterinarian to help determine the cause of the lesion you’ve noticed and to make sure it is treated appropriately. The vet will likely want to look at a sample from the area under the microscope to determine if there is an infection and to figure out what medication is appropriate for treatment. In the meantime, you can bathe Coco in hypoallergenic shampoo for dogs to clean the area, but this will likely not resolve the lesion.I recommend getting Coco on parasite prevention year round.

That spot on Buddy could be several things including allergies, skin mites, ringworm (which humans can get) or a bacterial infection. You can try adding in an omega 3 fatty acid supplement for dogs, this can help improve the skin health. You may also try changing his diet to something like Royal Canin or Nutro as they are aimed at skin health. You can wash the lesion with soap once a day and rinse well (don't wash his whole body, just the spot). Protect the area from licking or scratching. If it doesn't start looking better within about a week or if they get worse, have him examined by the veterinarian who may prescribe medications. Best of luck and please feel free to post any additional questions.

There is no way to diagnose this via a photo, I am afraid. Only a hands-on exam in combination with a brush sample or a swab can help identify whether this is a fungal or bacterial lesion or a sting or bite. I would observe it over the weekend, and should it increase in size, start to ooze or change in appearance other than fade, you should have a veterinarian examine this lesion. there is no one treatment for all these causes. Do not put any ointment on it , just observe it.

It’s hard to say from the photo. That could be an area where a tick bit Winston. It could also be some sort of puncture wound, spider bite or potentially a ringworm lesion. From the photo, the area looks swollen. Because of this I recommend to have him examined by the veterinarian with in the next 24 hours. A swollen tick bite or puncture wound could indicate the onset of an infection. There could also be a tick head or foreign object trapped in the skin. Ringworm generally does not swell but a deeper infection could. Make sure Winston does not lick the area and have him wear an Elizabethan collar. I hope this helps and best of luck. Please feel free to post any additional questions.
