Dogs innately want to protect you so they're going to bark when they hear an unusual sound…like a doorbell. When you yell at them they can interpret that as you barking along with them.
Jade Whitney is a Canine Behavior Specialist who says….
"They're going to bark to let you know someone is here it's their house… teach them a quiet command in a calm voice."
Two common training mistake are squirting them with a water bottle or making a scary sound (the pennies in a can method.)
"Squirting them is going to break down your relationship and make them bark more" says Whitney.
Dogs don't always see hugging as a form of affection. It can be misinterpreted as a sign of dominance.
If you are going to hug your dog make sure they are standing on their own so if they are uncomfortable they can move away.
Pet expert Robert Semrow says "here's the thing...animals smell...dogs can smell 1000 to 1 million times better than us humans… they want to smell the world that is how they're able to really live and enjoy"
Now that doesn't mean you should let them go wild and tag the neighborhood. Keep a loose leash until they get squirrely and then give the leash a little tug. If they don't stop - you need to stop. Teach them that you are the one in charge.
If your dog is sleeping don't wake him with loud noises. This can stress him out.
Great owners; Great dogs on the Lowdown.
