Tips: Greetings and "Good"-Byes

Some dogs can become overwhelmed by our behaviors when they don't really understand why we act the way us humans do. It is natural for us to be excited to see our dogs when we come home and fawn over them, showering them with praise for something they have no idea about or scold them for something they have not recollection of doing wrong.
The long and short of it is, our brains have a different set up. We process our long term memory and bank information like what we did and why. Dogs just let that go and move on. It is not important to them, they will bank the important facts like who we are and how they don't like men in hats because that angry man in a hat from when they were little etc. They do not bank the incident with the trash bin being emptied or the couch cushion being chewed or the potty they had to release on the floor.
So when the human they love comes home and sees the mess or lack of mess what should we do? The best thing for the dog is to come in like we have no dog. Do not acknowledge them for a few minutes until their brain switches from greeting "establishing pack reconnect" to home mode. You see when a pack reunites information is gathered about others where abouts and the leader is reestablished or reaffirmed. We may let our pack sniff us but, not reach out to them to offer them leadership status. This would confuse them later when we expect to be leader.
This goes for leaving as well. Remember, you never want to let your dog go pee and then call them inside or bring them inside and leave. Would you hurry up and pee if this happened to you? Would you come when called? Probably not. It is simple to have this as part of your exit routine and then simply wait a couple minutes before leaving. When you leave make no fuss, don't say" good bye, you be good today and no chewing up the couch pillows" (picture what you expect to happen) When it is time to go, just walk out the door. If possible have an uneven routine such as, go out different doors, carry stuff to table and sit down then leave(mix it up)
This takes some getting used to but, when you remember it is for the good of your dog, the good of your relationship and the good of your house it is a little easier to do. A dog you don't have to worry about makes your day enjoyable. Once you are home and in "home mode" you can snuggle and fawn over your dog as much as you want and always on your terms. Separation anxiety can cause destruction of your home and its contents including bodily injury of your dog and wreak havoc on your relationship because of lack of trust. This is perpetuated by scolding the dog when you return. They see you coming home with scolding and worry about your return when you leave which makes them more anxious and there by more destructive.
Also helping with anxiety, don't leave food out all the time because pack leader is controlling the food supply. You may give your dog a food treat (like a kong) before you leave because you are presenting it to them.
Break the cycle and build an easier leadership role by implementing these simple steps to a better balanced dog.
