You are, more or less, the dog's dad...you SHOULD be the alpha male in the house...and since you've presumably raised the dog from a pup...and are responsible for his housing, care, and feeding, that makes you the dad.
Personally, I don't consider myself to be the "dad" of our dogs...I had NO part in their conception. (no one saw a thing...you can't prove ANYTHING!) BUT, I am still the male parental unit...sort of.
My cat, however, I raised her from a pup. She was about 2 days old when we got her. Her biological mom was a feral cat who was killed by a car. Our daughter brought this little gray mouse-looking creature into the house...where, of course, my wife said, "We are keeping this tiny little thing and will TRY to keep her alive."
I ended up being the only one who actually cared for the kitten...bottle fed her, bathed her, etc...so I am the only "mom" she's ever known...and that's how she acts...like I am her mom. She follows me everywhere...sleeps so that she can either see me, or (preferably) have at least one paw touching me. She turned 17 people years old last Labor Day.
Clearest example of over parenting. You coddle your cat, so it expects to be coddled. Our cat already has a flat in Manhatten, a Porsche, and a 6-figure income on Wallstreet. And she's only 4 years old.
