My 1-month-old puppy is losing hair. Is this normal or a concern?

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!

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!

I am sorry to hear about Norik! We can see shedding at certain times of year, especially when the seasons are changing, however we would not expect a bald patch of skin as a result of this normal shedding. If Norik has a bald spot we would worry about things such as a hot spot forming (a bacterial infection of the skin), a fungal infection such as ringworm, ectoparasites, or other disorder. I would recommend Norik have an exam by his vet to check the patch of bald skin so we can figure out why he is losing this hair and treat appropriately!

Hello. Hair loss in a puppy can be a concern if it is excessive. The first thing we want to rule out is external parasites like fleas & mange mites ( Demodex & Sarcoptic ). Bacterial & yeast-based infections & allergies are also a possibility. You can bathe Blu in a flea shampoo to eliminate the possibility of fleas, but if she is intensely itchy & continues to lose hair, you will need to see your veterinarian for a diagnosis.

If, when the hair comes out there is no bald spot, then this is not concerning. If a bald spot remains, then you should have your puppy examined by a veterinarian, as it may have a mite or bacterial infection or a fungal infection.

Hair loss can be caused by a number of things. The most common one would be demodectic mange (caused by the Demodex mite). Other possible causes include fleas, lice, infections, ringworm, and allergies. I would recommend that you have Makivali examined by the vet to make a diagnosis and receive appropriate treatment.

Hi there! Thanks for using Petco Pet Education Center, formerly Petcoach! There is a variety of reasons that can explain alopecia or hair loss. The causes can easily be differentiated by the clinical signs associated with it and the physical exam findings. If Cookie is only showing some hair loss without scratching or overgrooming then it could conditions such as alopecia areata that can affect dogs and cats and usually resolves on its own. If there is evidence of scratching and you start noticing some redness or irritation associated with it, then other conditions such as allergies are possible. If you notice her overgrooming herself in that area then it could be something like psychogenic alopecia which is more of a behavioral issue. I think that since she is not having overt clinical signs and it is mostly hair loss, I think it is possibly transient and could resolve on its own. You can monitor this closely and if it does not resolve or it worsens then have her examined by your veterinarian. Good luck!
