Why is my dog biting his tail raw despite cones and allergy shots?

There are a number of [bitter sprays]() and anti-chew sprays which can be applied directly to the pet to prevent [licking](https://www.petcoach.co/article/why-does-my-dog-keep-licking-himself), but these are seldom successful in compulsive issues. I would be concerned that there may be an underlying source of discomfort or anxiety causing him to do so much damage to himself. I strongly recommend you get a full physical check up including his anal glands, hips and spine. Consider complimentary therapies such as [acupuncture or chiropractic care](https://www.petcoach.co/article/7-natural-treatments-for-dog-anxiety) to treat pain or anxiety. A [certified veterinary behaviorist](https://www.dacvb.org/search/custom.asp?id=4709) may be required to address behavioral concerns once medical causes have been ruled out.

The spot on the tail looks like a hotspot right now. Hot spots can be common with food allergies and fleas (which you are already treating). The article below discusses treating hot spots. If Summer can still lick his tail, you may need a long e-collar. https://www.petcoach.co/article/hot-spots-acute-moist-dermatitis-in-dogs/

Poor Girl! Without seeing her in person, it is impossible for me to know what caused it. It could be fleas. Mange usually causes hairloss on other places like the feet and face. She likely has an infection from chewing. I would first put a cone collar on her to prevent the chewing. I would then start her on Benadryl twice a day to help decrease the itching. If it isn't improving, I would have your vet take a look. Your vet will likely want to put her on antibiotics and possibly stronger allergy meds to help it heal. I hope this helps! https://www.petcoach.co/canigive/dog/benadryl/

Allergies can be frustrating to diagnose since there are many potential allergens. They can include flea bites, environmental/inhaled allergens or food allergies or sensitivities. It can also be caused by behavioral issues, such as boredom or anxiety. Place an e-collar (cone) on Lou to prevent licking. Discuss allergy testing, food elimination trials and hydrolyzed diets with your veterinarian. A short course of steroids followed by antihistamines may help stop any itch and prevent it from returning. This may be a seasonal issue or it could be year round. You can also discuss anxiety medications and behavioral modification with your veterinarian. When you see Lou licking, distract him and offer a task, exercise or treat to redirect his attention. If he complies, praise and reward him. Be patient and be consistent. Limit his exposure to chemicals and cleaners to see if it makes a difference. Remove any candles or air fresheners from the home as well.

This is probably caused by an allergic reaction. first of all make sure you de-flea Fenton regularly every month with a high quality spot on (ex. Advantage) as fleas are by far the most common reason for these reactions. If the fleas are not the problem, it could be an allergic reaction to food or an environmental factor. this is more complicated to treat and will sometimes require medications such as Steroids, anti histamines or cyclosporin in order to stop the allergy.

Most likely the fur feels different due to his chewing on the area. Chewing in this area is most often related to an allergy and most often due to a flea allergy. Even if we don't see fleas crawling on the dog, a few bites can cause a severely itchy response that can last for weeks. I would recommend bringing Thor in for an exam to be sure that is what is causing his issue. The vet can prescribe effective flea prevention such as Nexgard, Comfortis, Bravecto, or Simparica (or another they may recommend) and may prescribe an antihistamine or other allergy medication. In the meantime you can put an e-collar on him to try to prevent him from biting at the area and causing further trauma. A colloidal oatmeal shampoo and creme rinse such as Epi-soothe can also be helpful to decrease itching, as can a fatty acid supplement which are available at your vet and at most pet stores.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. I would recommend having a veterinarian examine Barrett so that the most appropriate treatment recommendations can be made. It sounds as though he is dealing with severe allergies and needs relief. There are multiple medications that can help with allergies. You should also consider the below products to aid in relieving the discomfort associated with a potential allergy: 1. Douxo PS Calm shampoo (found online) 2. Welactin omega 3 fish oil capsules (found online or at your local Petco) 3. Pramosoothe spray (can be found online) I hope these help! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
