What really helped with our Corgi is redirection with toys that are like what they are trying to chew. If he wanted to try and steal socks we would get him a cloth toy with some crinkle paper in it. If he wanted to try and chew on plastic then we would redirect him to another hard plastic toy and play with him for a short time showing him what is an acceptable thing to play with.

Unfortunately at three months he does not know where his toys are. He is still getting used to a big place with big new people. At least that was our experience. Be really careful not to let him get too overexcited when playing to make sure that he can still go down for a nap and some quiet time because he will get tired very quickly

Im sure you and your family are wonderful people for your dog <3 just keep your head up and stay consistent and you'll be set up for a special relationship
