Hi Omayra
A 5 month old puppy chewing carpets can be anything from normal puppy behavior (most common reason) to something nutrient related to a behavioral issue and so on. I would not rush into a nutrient deficiency diagnosis so quickly!
Before anyone can suggest any supplements for your puppy can you please tell us his current diet including treats please be as specific as you can.
What is his day like? Yard, Walks, Toys, People always around? How much time does he spend alone? Does he sleep and spend any other time in a crate?
Can you please also tell us what brand/type of shampoo and conditioner that you use and how often you bathe him.
And can you please tell us any medicine he is currently taking, including flea control. How much and how often and his vaccine history.
And last but not least has he had any blood, urine or fecal tests run and were there any abnormal or out of range results.
Is there anything you would like to add that will help us to know him better?
I don’t mean to pry but you must take into consideration the WHOLE dog to start figuring things out. Looking at a symptom or a behavior without knowing more about a dog usually results in treating a symptom instead of curing the cause of the symptom by returning the dog to complete and overall optimum health. This may not always be possible but starting with the whole dog is the way to go!!!
Keep Up The Good Work!!!
