Of course we can’t see the Angels. Because they are supernatural beings. But the Prophet (ﷺ) informs us that there is something that makes angels reluctant to enter our house.
A hadith from Ibn ‘Umar (may Allah blesses him), he says:
وعد رسول الله صلى الله عليه وسلم جبريل أن يأتيه فراث عليه حتى اشتد على رسول الله صلى الله عليه وسلم، فخرج فلقيه جبريل فشكا إليه، فقال: إنا لا ندخل بيتًا فيه كلب ولا صورة
Jibril (Gabriel) promised to visit the Messenger of Allah (ﷺ) but delayed and this grieved him very much. When he came out of his house, Jibril met him. The Messenger of Allah (ﷺ) asked him about the reason of delay, and he replied, “We do not enter a house in which there is a dog or a portrait” [Saheeh al-Bukhari].
“The portrait” here means the picture of living beings, such as picture of human of animal.
Yes, sculpture of living beings, the picture of them, and dogs can discourage Angels from entering your home.
The scholars say, that if Angles reluctant to enter our house then there will be lack of love and happiness. Filled with contention and hatred. Wal ‘iyyadhu billah.
