why when I want to see which CNAMES has a specific domain I can't see them using dig/nslookup? nslookup -type=any google.com

Are CNAMES protected against public petitions? Output from command:

;; Truncated, retrying in TCP mode.

CNAME records are public, you should be able to see them. If you're not seeing them it will most likely be the case that the domain has no CNAME records at all.

Try a couple different domains, especially subdomains as they usually contain CNAME records. e.g.

~ → nslookup -type=CNAME www.pinterest.com

Server:     2001:558:feed::1
Address:    2001:558:feed::1#53

Non-authoritative answer:
www.pinterest.com   canonical name = www-pinterest-com.gslb.pinterest.com.
