Introducing a new dog into your home can take up to six months before he adjusts. To feel comfortable knowing you, his new home and perhaps his new "friends".
That made me realize the same happened to me, and my children. With Olivia and me, we bonded right away, but with Max it actually took little more than six months.
Same with animals and families. That's why it is important not to compare or to remember the former dog "to much". It is easy, but dangerous!
It is an Amore to see every individual life as unique and special.
