My dog's bug bites won't heal, she bites scabs, now has hard bumps.

This presentation could be due to a trauma or localized spot of skin infection (likely to be caused by bacteria). Ideally a check up, appropriate disinfection and possibly antibiotics (oral, topical or in a shampoo formulation) are needed to solve the problem. The area must be clipped more and disinfection may be started at home with very diluted hibiscrub or betadine or salted water baths (twice daily). Buster collar may be useful as well to avoid any licking (if any).

The most important thing in getting a lesion relating to self-inflicted harm to heal will be to prevent any continued harm from occurring. This will likely involve obtaining an e-collar from your local vet or pet store and fitting it on Sugar. You can also put something like a t-shirt on the area depending on where it is. Also, without seeing the lesion, I can not advise you on whether or not an infection may be occurring and if antibiotics might be required. The itchiness from the lesion is not likely to stop until the healing process has at least partially started. As such, the use of the collar I mentioned in the beginning with be of the most importance. Hope this helps!

This presentation could be due to a trauma or localized spot of skin infection (likely to be caused by bacteria or fungal). A check up, appropriate disinfection and possibly antibiotics or antifungal meds (oral, topical or in a shampoo formulation) are needed to solve the problem. Disinfection can possibly be started at home with very diluted hibiscrub or betadine or salted water baths. Buster collar is useful as well to avoid any scratching (as you have used).

While insect bites are possible, another common cause of lesions as we see here is a secondary bacterial infection of the skin resulting in papules, crusts, and pustules which can be very itchy. Oftentimes these dogs need a course of antibiotics and either a steroid or a drug called apoquel to get the inflammation/itch under control. Sometimes the itching may be controlled with an antihistamine such as diphenhydramine, hydroxyzine, or cetirizine under the direction of your veterinarian, but oftentimes initially a steroid or stronger medication is required.

Thanks for using Petco Pet Education Center, formerly Petcoach! This is possibly due to allergies. It really comes down to figuring out what is causing her allergies so that they can be treated or the specific allergen avoided. A secondary infection is likely and also needs to be addressed. There are many things that can cause allergies though in most cases they can be broken down into 3 big categories: flea, food and environmental allergies. Allergies are usually worked up in a stepwise fashion starting with flea allergies as this is the easiest and cheapest to take care of. If not on a flea preventative, then it would be a good idea to get started on one. If already on one then it would be a good idea to change to something else (there are many new products out in the market). If not improved in 1-3 months then it is time to move on and check for food allergies by switching to a novel diet (new protein and new carbohydrate). If that does not seem to be the issue then you are left out having to check for environmental allergies which require blood and/or skin tests. Allergies can be very frustrating to deal with at first but so rewarding at the end when we are able to treat them effectively!
