We adopted a Covid shelter dog, she was traumatized our vet told us. She has chewed, blankets, towels, our clothes, 3 less expensive crate beds, etc. I bought one Gorilla bed and it passed the test ! Not one nibble. Oh, did I mention they thought she was 2 yrs old ? Well, she's grown and gained 10 lbs in 6 months !!!? This product truly does what they promise. Thank you.
