I have a 5 month old Boston Terrior and she has ear scabs and a big nose scab. Pet's info: Dog | Boston Terrier | Female | unspayed | 5 months and 8 days old | 9.6 lbs

I am sorry to hear about Myah! I would recommend bringing her into the vet for an examination with these skin lesions. We would be concerned about ectoparasites such as mange mites (not visible to the naked eye), fungal infection such as ringworm, bacterial infection, and more. They vet will examine the areas, may recommend testing such as fungal cultures or skin scrape and base treatment recommendations on these results.

It's probably an ear infection, often it cannot be seen from the outside. Ear infections are very common in dogs, it is usually caused by either yeast or bacterial disease. the treatment is usually simple and straightforward, you will have to take Pixie to the vet and get the ears checked, then a prescription ear drops will be prescribed according to the infectious agent.

I can't tell from the picture if there are legs or if they is just a scab? If there are legs then it is likely a tick. You cannot see ear mites with the naked eye and they are usually inside the ear canal. If it is just a scab then this is likely a localized infection. You can try putting some neosporin on it twice a day to see if it gets better. If it isn't improving, I would have your vet take a look at it to see if she needs any other meds to help it heal. I hope this helps ! You can give her benadryl if it seems itchy. See link below. https://www.petcoach.co/canigive/dog/benadryl/#!
