My dog has a target mark. Is it Lyme? Do I need an emergency vet?

I agree that these have a "bullseye" look to them, however we don't typically see bullseye lesions in dogs with tick disease, as they do in people (with Lyme disease). Often insect bites can leave this type of lesion, and I'd be wondering whether this was itchy or not, as it could be a mosquito bite or spider bite. Other things to consider would be ringworm and a bacterial skin infection (pyoderma). If Pepe is feeling well that makes me less concerned for tick disease, however based on your zip code Lyme is always a concern, so I would be inclined to get him tested for tick disease as you have found them on him recently.

That looks like a skin lesion to me, which could be from a tick bite. It could also be a ringworm lesion. Without seeing Dozer in person, I can't say for certain what is causing this mark. I recommend giving his vet a call today to make an appointment for him. The vet can diagnose what is causing the mark, and can prescribe a treatment for it. Best of luck.

Themise kesion are very suspicious of where a ticj may have been attached due to the inflammation and swelling and the target lesions. Lyme disease is transmitted by 1 type of Tick but there are other Tick disease caused by different types id ticks. With that degree of inflammation I would have your vet check those area and do lab work. It will check for Tick borne diseases and check for any changes in the blood from the illness if positive.

Keep the area clean and dry. You can use a diluted Betadine or chlorhexidine (Hibiclens) solution to clean the area daily. Tick bites frequently result in a red, raised area (tick bite granuloma) after the tick drops off or is removed. The good news is that they resolve on their own within a few weeks. Resume Iggy's tick prevention and perform tick checks after being outdoors. You can have him tested for tick borne diseases in 6-8 weeks. https://www.petcoach.co/article/how-to-check-your-pet-for-fleas-and-ticks/ https://www.petcoach.co/article/what-to-do-if-you-spot-a-tick-on-your-pet-or-in-your-home/

Thank you for sending the pictures! From what I can see, it looks like this lesion is only affecting the outermost skin layers, with the underlying tissue layers remaining intact. It's certainly possible that this lesion is from a traumatic injury, like the rubber bullet you'd mentioned, but it's equally possible that this is an infectious condition, like mange or ringworm. Since there is a good bit of skin damage that's bloody, it stands to reason that this type of lesion could become infected rather quickly, particularly if Crimson is licking at it at all. Even though we're now several days past the initial injury, I still recommend taking Crimson to her vet for an in person exam to thoroughly assess this lesion. Your vet may need to do some diagnostic testing to rule out infectious issues. Depending on their exam findings, your vet may need to prescribe oral antibiotics and/or anti-inflammatory medications to aid in the healing process. Until your vet visit, be sure to prevent Crimson from licking at this lesion at all by putting an e-collar (cone) on her. I hope that she's on the mend soon!

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Duke. This could be ringworm or a sign of lyme disease, but yes it could also be a black fly bite. Black fly bites do not need any treatment. I honestly cannot make a diagnosis from a picture (and neither can a vet student), so I would have him seen by a vet. The vet can diagnose what is causing it and what treatment, if any, is needed. I hope this helps!

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.
