Are non-slip rubber bases durable, or do dogs chew them off?

This is the most common complaint across retailer-customer reviews regardless of brand. Even on otherwise well-reviewed stainless and slow-feeder bowls, owners report rubber rings loosening in the dishwasher or being chewed by puppies. Several r/dogs commenters suggest supplementing with Velcro or a silicone placemat if your dog actively pushes the bowl.
