My dog is obsessed with me, how can I get her to pay more attention to my husband who has always wanted a dog of his own?!?

Animals imprint on whomever shows them the most attention, especially the one who feeds them.

Dogs will choose who they prefer, nothing anyone can do to change that fact, just learn to deal with it the best that you can. This can apply even if both spouses provide equal attention, and basic care.

It's individual the same as no one can force you to like someone....

Does your husband walk the dog or do you?

For many dogs going on a walk is the highlight of their day. I got dogs pay more attention to me than their owners just because I walked them and their owners did not.
