I purchased AirTag cases in August for our two dogs. One tag didn't last a week before tearing. After a brief lecture from the CaseMate rep. about their responsibility to replace a tag only one time, Case-Mate replaced torn tag. Now the replacement tag has also torn. Both of the dogs have the same brand & size collar so the collar isn't the issue. Fortunately one side of the tag held up so we did not lose the AirTag itself. The tag on the 9 year old has held up fine, but the tag on the 2 year old has ripped both times. It seems that these tags are not durable enough to withstand the activity of a young dog. I have not yet reached out to Case-Mate about the damage to the replacement tag. However even if they make an exception to their policy of single replacement, I'd say they are not worth the trouble.
