Does maulnutrition in dogs cause hair loss?

My family and I just got a dog not even a week ago. He was definitely not fed much because you could see his bones. He also has a lot of hair loss throughout his body. Is this because his prior owners did not give him the nitrition he needed to survive?Does maulnutrition in dogs cause hair loss?
yes, that could be a reason, another reason is because he is full of fleasDoes maulnutrition in dogs cause hair loss?
Yes, this could be one possibility but, it could also be external or internal parasites. Or it could a different kind of medical issue.
You might want to take the dog to a vet. It could have mange or a flea allergy also.
In my opinion it's 98% chances due to malnutition. My aunt had 2 dogs that she adopted cause they were abused by the previous owners and once they stated having a proper diet and a daily walk in the beach, they stopped losing hair after a few weeks.





If that does not work, I would def go to the vet.


Hope it helps!
Yes, it definitely can.
Poor nutrition certainly can cause hair loss. However, you really should schedule him with the vet ASAP to get him checked out and make sure that there isn't another reason for the hair loss as well. Parasites (mange mites and fleas particularly) can cause hair loss. Ringworm, a fungal infection that is contagious to humans, can also cause hair loss. If he is an adult dog the hair loss could also be caused by a number of diseases that aren't contagious.
