My guy was abused the first 8 weeks of his life until we got him.
I think he is scared for life.. He does however play and give us kisses with his bad breath
But its easy to see that Max went tru sh*t his first weeks here on planet earth. He is now almost 1 year old.. Still looking like he is being scolded or pushing when we pick him up or ask him to sit..
He does get better as the days/weeks/months passes by but Im not sure he will be healed 100%
I think your guy is bit the same as Max in that way.. Just love him & show that love to him so he feels and hears it.. Eventually he will change more and more..
Just think about how lucky he is.. Now he is finally with a family that truely does appreciate him!! Nothing is more important!!
