After a dog enters a new family, it will take 4-6 months to recognize its second owner. As long as the new owner and family treat the dog sincerely, after a period of time, the dog will accept the new owner from the bottom of his heart and integrate well into the new family environment. Dogs have very high IQs, and they can distinguish between likes and dislikes, so as long as they are good to the dog, they will trust and obey the new owner.
Some dogs will recognize their new owners, but they require a lot of care and love from the new owners. If a dog is abandoned by its first owner, the new owner needs to be patient enough and give the dog enough trust. During the maintenance period, you must take good care of the dog and take the dog out for activities regularly. Play with the dog every day and spend more time with the dog. The dog's emotions will change, and the dog will slowly accept its new owner in the future.
Different dog breeds have different loyalties. Dogs such as Tibetan Mastiff, German Shepherd and Caucasus will only recognize one owner in their lifetime. A dog's dependence on its owner mostly depends on the owner's dedication to the dog. The more care the owner gives to the dog, the more sense of security the dog will have, and the shorter the time it will take for the dog to recognize its second owner. The more attached a dog is to its previous owner, the longer it will take to accept a second owner.
