Oh No!!!!
Not as Alpha!!!!!!!
Just as one step above Daisy!!!!
YOU are Alpha, you are the one that makes the decisions - YOU remove the support of the pack when he is being silly - YOU show him how to deal with the stresses in life in a different way - YOU give him no attention until he does it YOUR way!!!
You only allow him to have a subtle difference in status to Daisy, that is all he is trying for at the moment.
Every little thing I have suggested you do is designed to make him feel settled, take the worry out of Daisy's life and carefully and without conflict set YOU and your husband (what is his name? I feel awful saying, "The Husband!" all the time!") as the only people in the house who have half a chance of being clever enough to think of being the Alpha!

In wild canids it is a position that few even aspire to hold! If you have a dog like this then don't call me!!
Naturally ,though, when the dog sees an opening, a situation where, for a brief time he can lead the behaviour of the pack most will take the chance. They will then expect others to take control of feeding and normal life.

This is a system that works and that makes all members of the pack feel safe and secure.

The basic lessons that owners can come away with are these.......

You have to be the Alpha

All other humans in the home have to be above the dog...many people think that this means kids should train, hit, torment or show how good the dog is with kids by letting the kids play tug of war with the dog

You have to understand the things that motivate your dog, different dogs have a different wish list of things they want

I truly believe, even although it seems I am alone these days, that food rewards should be used as a last resort and for as short a period as possible.

Dogs DO NOT sleep with the Alpha people in the house! (Nine times out of ten you will start this because you have a love hound and never will it cause a problem....BUT!)

NEVER, NEVER, NEVER loose sight of the fact that your dog, however special, is a dog and needs dog rules and dog language and dog fairness and dog understanding to really thrive, be happy and enjoy life.
