How long does it take to recognize the owner if you buy an adult dog? It can take several weeks for an adult dog to recognize his owner, depending on the dog's personality and your educational method. Most importantly, you need patience, love and perseverance to help your dog build healthy connections and trust.

If the owner takes good care of the dog and is willing to spend a certain amount of time with him every day, he can basically recognize the owner within one and a half months as soon as possible.

However, if the owner usually has too little companionship with the dog, or the dog has deep feelings for the former owner, it will take as soon as 2 to 3 months to re-recognize the owner. Some more loyal dog breeds may take longer, such as Tibetan mastiffs, pit bulls, etc.

Compared with adult dogs, puppies will recognize their owners for a shorter time. The best age for dogs to recognize their owners is generally between 2 and 3 months old, which is also the time for most people to pick up new dogs home.

However, dogs usually show strong behavior of recognizing their masters only around 6 months old, such as actively exposing their belly to seek caress, or waiting at the door for get off work every day, and frequently wagging their tails when they see their masters. These are manifestations of dogs trusting their masters and can be used as a basis for dogs to recognize their masters.
