My dog has a new rash under his arm. Could it be Lyme disease?

Keep the area clean and dry. If he is licking, place an e-collar (cone) on him. Make sure he isn't dragging or scooting because his anal glands are full. The doxycycline, although effective against the Lyme organism, may not be the best choice to treat a bacterial skin infection. Discuss systemic and topical treatment as well as any underlying causes (fleas, mites, allergies, etc.) with your veterinarian.

Hi, it seems like the rash is quite severe and definitely will cause pain. In general, rashes in this area are indicative of underlying allergies and most likely will reoccur. My point of view is to have June seen by a vet so she can receive prompt treatment that will relief pain and inflammation and to make a long term plan. The vet will also go through options that might be used at home once the inflammation is under control. Hope this helps !

Ticks can transmit disease such as lyme disease. This can cause a rash or bruising, lameness and tremors, and generalized not feeling well--often non specific signs. I would take her to the vet to have a test ran for tick borne disease and have a CBC performed to make sure there is no signs of a decreased counts that can cause bruising. It could be inflammation from the collar but I would not risk that chance without testings due to the extreme side effects of tick borne disease.

This may be local irritation or infection. If Kiely is licking at it, place an e-collar (cone) on her. Keep the area clean and dry. This may be enough to allow for healing. If the rash worsens or spreads though, she will need to be examined by your veterinarian. Antibiotics, anti-inflammatory and/or antihistamines may be indicated depending on the diagnosis.

Poor Riddick! Unfortunately, this looks like it is infected. You can try some benadryl and neosporin twice a day. See link below for benadryl dosing. I would not let him lick it. You can put a cone collar on him to prevent this. If he licks it, it will never heal. If you aren't seeing much improvement, I would have your vet take a look at him. Your vet will be able to start him on oral antibiotics and stronger allergy meds like steroids if needed. I hope this helps! https://www.petcoach.co/canigive/dog/benadryl

Hello, sorry to hear about Lenny. This could indeed be associated with his allergies and has not developed a local skin infection. This means that Lenny may require topical and/or oral antibiotics to treat the rash. Lenny should be evaluated by his veterinarian if this rash is not improving on its own or if its getting worse so that he can have medications. Hope this helps and best of luck.

Hello and thank you for your question. From the pictiures and your description of the lesion, I am more concerned for ringworm. Ringworm is a skin parasite that is transferable between animals and people and usually manifests as a distinct ‘target’ or ‘bullseye’ skin lesion. To address your concern for Lyme disease (a tick borne blood disease), in dogs, the signs typically include lethargy and lameness. There may be an associated skin lesion due to a tick bite, however that lesion with out the tick usually goes undetected. Lyme disease can easily be detected by a simple blood test preformed by your veterinarian. While not an emergency, Lewis should definitely see his veterinarian as soon as possible for diagnostics and treatment. Until Lewis can be seen by his veterinarian, I strongly advise that you or anyone else in the house hold not touch the lesion and continue to exercise proper hygiene. If you or anyone in the household has a similar lesion, they should be seen by their physician. Hopefully this information helps. Best of luck!
