My 7-month Bernedoodle has red skin under his chin. Is it allergies?

This is probably due to an allergy, although it could also be infection or mites. First of all, in order to rule out skin parasites, you will need to treat with a high quality flea treatment (advocate or advantage), then ask the vet to perform a skin scrape - this might reveal an infection or a mite infestation. If all of those came back negative, the next step is to treat the allergy symptomatically and try to discover the cause of the allergy. Three main type of allergies are usually affecting pets: food allergies, flea and parasite related ones and environmental type (allergens coming from trees, pollens, dust etc etc). Some medications can be given by the vet in order to repair any possible skin lesions (like steroids and antibiotics). Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

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 his 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 medications such as Apoquel or prednisone which may help with the itch. 

 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!

Thank you for submitting your question regarding Chloe. Yes, she should see her veterinarian. She may have an infection within the hair follicles of her chin. Sometimes this is due to the area being moist such as with a dog that drools a lot. Other times it is related to an allergy or an overgrowth of mites. Sometimes I do not find a definitive cause. An allergy will be more likey if she is itchy and has other skin lesions as well. She may require skin testing and will likely be sent home with antibiotics. I will usually prescribe medicated wipes as well. In the meantime, keep the area clean and dry. Try to discourage her from pawing at her face or rubbing her chin along the carpet. This will irritate the area further. I hope this information helps!

These look like acne type lesions to me and can occur in dogs secondary to allergies or contact hypersensitivity from things like plastic food bowls. A skin growth or insect bite might be another possibility. I'd recommend having your vet take a look in person to determine what these are - they might recommend taking a sample using a small needle to examine under the microscope.

Monte's red bumpy shin could be due to a bacterial infection similar to acne, parasites in the pores of the chin or an allergic reaction. Treatment is dependent on the cause and your veterinarian will likely get an idea of the exact cause after a physical exam. You can try adding in an omega 3 fatty acid supplement for dogs, this can help improve the skin health. You may also try changing his diet to something like Royal Canin or Nutro as they are aimed at skin health. This will helps with allergies and acne. Pets with acne also do best if the food/water dishes and toys are washed on a weekly basis. Also change the dishes to ceramic or stainless steel. Allergic reactions may require additional systemic medications or a diet change where as acne often responds to a medicated wipe. Parasites respond to an antiparasitic medication. Also protect the area from trauma by having Monte wear an elizabethan collar at all times. I hope this helps and best of luck.

Thank you for using Petco Pet Education Center, formerly Petcoach! Charlie is adorable! I can see the bumps on his chin - these may be caused by a skin infection, which can be very uncomfortable and itchy. I recommend having Charlie seen by a vet as soon as possible as Charlie may need antibiotics. In the meantime, you should try to keep the area clean and consider getting Charlie an E-collar or "cone" to keep him from scratching the area.

Unfortunately, without physically examining the area and potentially performing some diagnostics, I can't say for sure what sort of lesion that is. At first glance, it looks like something that could have been self-induced due to a primary issue causing itchiness. You should probably schedule a veterinary appointment and in the meantime get a cone to prevent your pup come itching the area further. If you do not believe your pup is itchy, then I would be more concerned about some sort of animal bite or bacterial infection. Hope this makes sense.
