Can someone tell me how to stop a dog from laying in our flower bed?

She obviously likes the feel of the cool soil. Training is your best option and I would provide her with another space, if at all possible, so she doesn't smush all your flowers. I would also discuss with your son and see what he can do to help. They are great dogs, she just needs to learn her boundaries.

Take a stick about 8" or 9" long and push one end straight down in the ground about halfway so the other end sticks out of the ground about 4". Put in some more sticks spaced a few inches away from each other until the area you want to protect is filled with sticks poking out of the ground.

You don't need a stick with a pointed spike on the top that could cause an injury, you just want to make it impossible for the dog to find a nice smooth spot to lay on.

My shepherd used to dig and lay in the garden too we solved it my making a bunch of "shake can" (empty soda cans with 6-8 pennies in it). We started by shaking the can at her when she got near the garden after she got the idea that the can made a bad noise. We just strung up a string with the shake cans hanging 6 inches apart as she would try to go in garden on her own can made noise after 3 days she stopped trying Good luck

sprinkle pepper in area where she lies

Our neighbor's dog would come dig up my flower bed and lay in it. Solved that, by putting field stones/bricks under my mulch in different areas that he dug up, and then I plant my flowers around that stones/bricks. No one knows stones and bricks are under the mulch, but me and that pesky dog!

We had a small (100 lb) black lab who enjoyed the cool spots where we were trying to landscape. We stuck pokey sticks in the flowers, about 4" apart. Then our local landscapers made plant suggestions that we interspersed among our pretty flowers so he had the cool spots he enjoyed so much on plants that his delicate size didn't smoosh. There are creeping thymes, sedums are readily available, you just have to keep him off long enough to get rooted. This was after the chewing and digging phases.

But our babies give us back more more than we give them. He really seemed to get the idea quickly when we moved his resting spots. Our big issue causing us to rethink the flowers was his choice spot next to the gate in the back yard. I don't care how miserable I made that spot he was going to use it. The stupid humans here finally realized he could lie in this one spot and see most of the front yard. So we moved the flowers over about 3' away from that corner. Put a peony on the outside of the fence and a climbing rose on the fence. We put some grass right into that corner and then the flowers along the fence.

Some times you have to notice why they've chosen a particular spot and decorate around it. After we started paying attention life was better. Still had to use pokey sticks in some flowers but rarely as he got older. Also, let me mention again he was black. So he needed shady places.

Great Pyrs have enough fur coat for 2-3 dogs. They may be white but they definitely appreciate shady spots. Remember they were bred as guard dogs so they need cool spots where they can see out over their territory. Good luck.

THANKS TO EVERYONE FOR THEIR HELP.

I DO HAVE ONE MORE QUESTION .

DOES ANYONE KNOW IF YOU CAN CUT A GREAT PYRENES' COAT, FOR THE SUMMER. SHE IS ALREADY GETTING REALLY HOT & I'M AFRAID WHEN THE HUMIDITY GOES UP,( INDIANA), SHE WILL GET HEAT STROKE.
