Why is my dog scratching with a bald spot on leg and bumps on ears?

This looks like an area of skin infection. The smaller two bumps are pustules and the larger area is a pustule that has ruptured. Sometimes, if confined to a small area, these can be treated with topical antibacterial medication. If, however, it is more widespread your dog may need oral antibiotics. I hope this helps. If you have any other questions please let us know!

Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. Based on what you are describing, and the pictures, I suspect that Willow may have an infection with ectoparasites, such as mites or fleas, that are causing her to be itchy. Your veterinarian can perform a skin scrape and evaluate the cells under a microscope to look for evidence of infectious agents. Please ensure that Willow is on a monthly topical flea and tick preventative that you purchase from your veterinarian; NOT one that can be purchased from a pet or grocery store, as these are not regulated and can be very toxic to pets. Willow could also have allergic skin disease, secondary to food or environmental agents. You can talk to your veterinarian about trying a diet trial to determine if Willow's itchy skin resolves on a particular novel protein diet. The thickened ears can be due to chronic ear infections, so your veterinarian will be able to examine the waxy debris under a microscope and prescribe the appropriate medication based on whether they see bacteria and/or yeast in Willow's ears. I hope this is helpful!

This redness indicates inflammation and is usually itchy. This is often due to one of two conditions. 1) Allergies - this can happen suddenly and is usually due to an environmental (i.e pollen) cause. https://www.petcoach.co/article/how-to-tell-if-your-pet-has-allergies/ 2) External parasites - fleas, lice and mites can all cause intense itching. It's good to check her for fleas and get treatment if needed. This pattern is more suspicious of mange, which is a mite infestation. A veterinarian can check for these mites and prescribe treatment. One thing you can do for itchy skin, is give a bath with cool water using an oatmeal or aloe shampoo. You can get these shampoos at the pet store. Below is a link with more helpful advice for relieving the itch. https://www.petcoach.co/article/4-great-strategies-for-relieving-your-dog-s-allergies/ I hope this helps you to identify the problem. If not, then it would be worth taking her to the vet. We can usually discover the cause quickly and provide the best treatment.

On the leg she has a hot spot, this is usually caused by skin allergies and aggravated by licking. i can't really see anything abnormal on the ear but it could be related to the same problem. your vet can provide treatment for this condition.

Poor girl. This looks like classic allergic dermatitis which is likely due to an adverse reaction to something in her environment. She now has an odor due to a secondary bacterial or yeast infection. She will need to see your vet to have the skin tested to determine the kind of infection, then started on medication to clear this up. She will also need allergy medication to help calm down the itchiness and redness. Two viable options for most dogs with skin allergies are either oral Apoqeul or injectable Cytopoint. There is also allergy testing available through your vet, if you are interested in getting allergy shots formulated for Maggie. Here is more information on skin allergies in pets--> https://veterinarypartner.vin.com/default.aspx?pid=19239&id=4951973 Until you can get Maggie in to be seen by your vet, you can try an over the counter pet formulated spray to help alleviate the itching. A "hot spot" spray or one that contains hydrocortisone would be most suitable for this. I hope that Maggie's skin improves soon! Best of luck and take care. : )

I looks like a hot spot. I suggest you use apply hydrocortisone spray or hydrocortisone cream to the affected area 2 times per day. If after a week or so it is not looking better then he should see your vet. ( https://www.petcoach.co/dog/condition/hot-spots/ )

It looks like Lila may have what is called a hotspot (localized area of infection). When they lick the area they can make it extremely worse very fast. I recommend taking Lila to a veterinarian to get the area clipped up, cleaned up and have antibiotics +/- topical medication. I recommend in the mean time going to a pet store and getting an Elizabethan collar for her so she stops bothering the area. This does not look like mange. I hope see feels better soon and thank you for using Petco Pet Education Center, formerly Petcoach!
