Dog has become possessive of her bed?

Answer 1

The dog has probably buried something in it's bed and doesn't want you to find it. My dog does that quite often.

Answer 2

It’s important to establish boundaries with your dog and reinforce positive behaviors. You can try redirecting her attention with toys or treats when she shows possessive behavior, and consistently practice commands like “leave it” or “drop it.” You may also want to consult a professional dog trainer for further guidance.
