Why does my 3-month-old puppy have small bald patches on his fur?

Thanks for using Petco Pet Education Center, formerly Petcoach! Thanks for also adding photos. Since I can’t see Prince McArthur up close I can’t for sure but it is possible he has microscopic mites. These mites are not itchy and not contagious but can cause hair loss especially in young puppies. I recommend taking him to a vet so they can look with a microscope and get him treatment if necessary. Good luck and kisses to Prince McArthur!

Thanks for using Petco Pet Education Center, formerly Petcoach! There is a possibility Colt has a skin mite called demodex (mange). These mites are microscopic and don’t cause the pet to scratch. I recommend taking him to a vet where they can scrape his skin and look for the mite with a microscope. They can also look for a secondary bacterial infection from the mite. Once they have a diagnosis they can prescribe him the correct medications to treat his skin. Good luck and kisses to Colt!

It's tough to say exactly what's causing Pablo's patch of hair loss from a picture alone. I agree that I don't see any redness, scaling or signs of inflammation in the picture. Some possible causes can include scar tissue from an injury or burn, infectious conditions like mange or ringworm, a sebaceous (oil gland) cyst or histiocytoma. Pablo should be examined by his vet so that diagnostic testing can be performed. It's likely that your vet will need to take samples from this area to be evaluated under the microscope. Once the cause of this issue is diagnosed, then your vet will be able to determine the best course of treatment. This is certainly not an emergency, so if many of your local vets are currently closed or have less availability, it's not a big deal if you need to wait a few extra weeks. I hope this helps and that all goes well for Pablo!

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Sammy and for providing a picture, it's very helpful. In the picture, I swear I see some dry, flakey skin. I'm wondering if he has a skin infection causing the hair loss and flakey skin. Without seeing him in person, I can't make a definitive diagnosis. I would have him seen by a vet to have this diagnosed and treated. Give his vet a call to make him an appointment. I hope this helps!

Thanks for using Petco Pet Education Center, formerly Petcoach! I'm sorry to hear Zulu is having skin issues. Areas of hair loss can be due to a variety of causes, including skin parasites (mites or fleas), allergies, an infection (bacterial or fungal), or another underlying medical issue. If the spots are worsening or spreading, or if they are itchy/seem uncomfortable, I would recommend Zulu be evaluated by her regular veterinarian to determine the underlying cause for her hair loss, have any necessary testing done (skin scrape, culture) and start on any treatment (parasiticide, anti-itch medication, antibiotic) that she may need to resolve it. Good luck!

Hello there, Round, circular patches of hair loss are often indicative of a severe skin infection. Simon needs to see his veterinarian this week. They will recommend testing some of his skin to see if bacteria or fungus is causing these lesions to know which medications to use. They may also recommend medicated shampoos. There may be an underlying predisposing factor in this skin infection, such as an allergy to an animal protein in his diet or the environment. I hope this helps.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Lily Cruz! Is Lily scratching? I would have her seen by your Vet. The most common causes of excessive shedding and areas of balding are: demodex (non-contagious mite), ring worm and a skin infection. Demodex can be easily treated with one of the oral flea/tick preventatives (Nexgard, Simparica or Bravecto). Skin infections are treat with antibiotics or anti-fungals if it is yeast. Ring worm can be a bit more complicated. I do not think it is normal shedding because she shouldn't have areas that are thin or balding. I wish you the best!
