My gerbil has a brown sore on its nose and greasy fur. What's wrong?

Thank you for using Petco Pet Education Center, formerly Petcoach! I can see the hairloss you are referring to. This would commonly be caused by overgrooming by a cagemate, but since Jim lives alone, he could be overgrooming himself due to boredom. He may also have mites, a skin infection, or an autoimmune condition. I would recommend having your vet take a small samples of skin from the area and sending it off as a biopsy to definitively determine what is going on.

That could be just an injury but it could also be the start of a tumor. Gerbils kept in a wire cage will often spend hours chewing on the cage bars, and this will rub off fur and irritate the nose. The simplest solution to do is keep your gerbil in an aquarium with glass sides. Glad you changed the bowl. I hope you got one that is ceramic or glass - that way she can't chew it. Do you have chew blocks for her? http://www.oxbowanimalhealth.com/our-products/hay/harvest-stacks-western-timothy-with-carrots https://www.petco.com/shop/en/petcostore/product/you-and-me-wood-chew-sticks-for-small-animals She may need a better diet. I don't know what you are feeding her but I suggest you use a premium diet like Oxbow. This may curb her chewing on other things. https://www.petsmart.com/small-pet/food-treats-and-hay/food/oxbow-essentials-healthy-handfuls-hamster-and-gerbil-food-5173696.html I, of course, would recommend you take Yuki to a vet for an exam. If you don't want to do that just yet I suggest you just monitor the nose for now. Do not apply anything to the nose topically because Yuki will just lick it off and ingesting those topical medications would not be good for her. Hope this helps. Best wishes!

Thanks for reaching out about Ghost and including a photo. By the looks of the picture, a fungal dermatitis (ringworm) should be considered. This is contagious to other rodents and possibly humans. A veterinary visit is recommended to assess and provide a diagnostic/treatment plan. AS this is close to the eye, systemic anti-fungal medications are preferred as opposed to topicals that might get into the eye. Good luck.

It's possible there could be an injury to the nose or some dried-on discharge. I would use a clean washcloth to gently remove the debris and see if it returns. If it does return or Stuart shows any additional signs of illness, scheduling a vet checkup to rule out issues such as an injury or respiratory issue is best.

This is likely just a pigment change and no big deal but of course, without seeing it I cannot say for sure. If any of the areas look like growths, scabs, scales, flakey or in any way abnormal besides the color change, then I would have your vet take a look. Your vet will be able to ensure there isn't any type of bacterial or fungal infection that needs to be addressed. Keep a close eye on her.

Hi, and thanks for your question. 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 eventually be started at home with very diluted hibiscrub or betadine or salted water baths. Hope this answer was helpful, but 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 reaching out about Snuggle. Dried crust around the nostrils is often an indication of the upper respiratory/sinus infection. Could also be inflammatory, dental problems and others. Bald spots behind the ears are usually normal as long as the skin is not crusty. A veterinary visit is recommended to assess and provide a diagnostic/treatment plan. Just because one has a runny nose and the other fine, does not mean not a concern. Good luck.
