Laurië ripped to pieces 4 beds in her first two years
And pulling the stuffing out of soft toys is one of her favourite things in the world.
They usually grow out of destroying our things. That's why it is good to puppysafe the house and not have any shoes, decorative pillows, rugs etc around the first year at least. Because when they don't have the opportunity to make a habit out of destroying things in their "teens", they generally leave our things alone as adults.
But if they love destroying stuffed animals, my experience is that they will keep doing that. I only buy the cheap rats from ikea for Laurië, they last longer than other soft toys for some reason and it's not a big deal when she destroys them. She currently has two ikea mice, both without stuffing
For her bed I had to put it away if she was very hyper, it was when she got overly excited that she chewed her bed. I also made sure to stop her if she chewed on it and gave her a chew toy instead. Eventually she left it alone. So I always recommend people buy a cheap first bed until they know what type of puppy they have.
She is 10 years old now and she stopped destroying things 8 years ago. But if we have company and she gets very hyper she will sometimes try and chew her blankets, never our things though. So if I see her getting the Zoomies and start pulling her blankets out of her bed I usually put them away until she calms down
Cardoard boxes are the best things ever! She loves shredding them! I usually let her, they take less space in the recycling bins as confetti anyway.
