They do, of course, have a preference, BUT they can learn to love everybody! Do not despair. Be patient and build trust. Our CAG prefers me but my husband has a great relationship with him. The only difference is in the evening he likes to cuddle with me, and that is the only thing that cannot be changed. Brutus is affectionate with my husband all the rest of the time. That's pretty good, don't you think? Right now they are having one-on-one time in his office. Brutus loves us both, and you can develop the same situation too.
