My two years old cairn terrier has lost is undercoat. Is it normal and will it grow again. He is health and has no skin problem . Thank you
Welcome! My name is***** am a UC Davis graduate, and currently, a Medical Director of a veterinary hospital.
I am sorry to hear about this concern.
Well, I would say there is absolutely no reason for the coat not to come back. Many pets will have substantial changes in their coat as they age and with seasonal changes.
Assuming, there are no other issues like underlying allergies, mange (demodex or scabies mites), or some endocrine condition (which would not be expected at this age), yes, the coat should return over time.
If you are observing any excessive licking or chewing of the legs or especially of the paws, that could suggest a underlying environmental or food allergy. So, keep that in mind.
Good Luck!
